Current research has focused on equipment configuration and variables for higher yields of the oils; methods of upgrading the oils for compatibility with existing fuel infrastructure and engines, and various tests to characterize the products or test their applicability as fuels. This paper reviews the progress in experimental work around intermediate-fast pyrolysis (hot vapour residence~1-20s; moderate to high liquid yields) in the past twelve years. The review focuses on the experimental scope, equipment used, preparation of raw materials, experimental design and characterization of bio-oils. Experimental work covering actual applications of the oils are not covered in this review paper. The feedstocks mostly researched on in IFP were rice husks, followed by pinewood, Jatropha curcas cake and rapeseed respectively. Most IFP studies have been done on woody biomass (over 100 different feedstocks) due to their consistency, followed by agricultural residues then herbaceous energy crops. Lignocellulosics proved to be the veteran organic feedstocks (~95% of IFP) ahead of non-lignocellulosic biomass (~5%). The most applied technologies in recent years, were fluidized bed followed by the free fall reactors. For the experimental design, most papers reviewed used the simple single parameter method, while a few used the central composite rotatable design and full factorial design methods. The characterization tests mostly conducted on the oils were the pH, viscosity, Karl Fischer titration and calorific value.","PeriodicalId":6671,"journal":{"name":"2019 7th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"44 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84236593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Theoretical model was used to study the effects of the indium (In) incorporation and nitrogen (N) concentration in the GaInAsN material. In order to implement this idea, a simulation program was developed to determine the strain effect on the band energy by taking into consideration the influence of In < 25% and N < 4%. In this study we have used the Band Anti-Crossing (BAC) model. Indeed, the strain reduces the band gap energy, and the nitrogen incorporation splits the conduction band into two subbands E+ and E-. In the correct condition, we also treated the impact of indium and nitrogen concentrations on the absorption coefficient of the GaInAsN/GaAs structure. According to a particular sequence, the raise of these both materials concentrations In and N results in the increase of the absorption coefficient. This work allowed us to optimize the In and N concentrations to raise the efficiency η= 22%, with strain equal to 1.5% of the solar cell based on the GaInAsN/GaAs structure.","PeriodicalId":6671,"journal":{"name":"2019 7th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"37 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86922278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To maintain a comfort level of living under this arid climatic condition, Residential houses need to be equipped with necessary facilities and high-power home appliances such as Air-Conditioners, water heaters, refrigerators, pool pumps, laundries and so on. Also, electricity cost could be very different at peak time and non-peak time through the day. To achieve a better cost-efficient electricity consumption, optimization control of load consumption for local residential house is studied in this paper. Firstly, a dedicated house model with thermal dynamics under local conditions is developed in this paper. Based on this model, optimal cost-oriented load control and consumption management based on optimization tool is proposed. Also, by designing constraint criteria, the comfort level of housing indoor temperature is guaranteed and energy consumption upper boundary is restricted. Finally, the optimization control scheme is verified through a scenario under typical seasonal weather conditions. The results shows that the lowest cost of energy consumption can be achieved by the proposed optimization control of house load management.","PeriodicalId":6671,"journal":{"name":"2019 7th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"44 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89579485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Indeed, global warming is a reality and air pollution is worrying especially in large cities. In addition, the depletion of fossil resources is looming. Electric vehicles (EVs) are currently considered as the promising solution for reducing the dependence of transport on fossil fuels. Nevertheless, the overall adoption of these vehicles is disturbed by range limits of EVs. Therefore, it is necessary to predict the required power to drive and plan for charging whenever needed. The aim of this paper is to introduce a software tool permitting to predict and estimate energy consumption for any desired road. The software tool is based on mathematical model of the EV, which relates the energy to different factors such as the velocity, the acceleration and the road slope. In other side, this paper presents a comparative study between the highways and the trunk roads. The road chosen is Marrakech to Casablanca based on two different driving cycles, each one corresponding to a specific road. This method can be used for any EV, which the characteristics are known. Using the proposed model, the results show that EVs are more efficient in trunk roads than highways taking into account the energy recovery during the frequent braking.","PeriodicalId":6671,"journal":{"name":"2019 7th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"46 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90449193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of these parameters is the temperature distribution inside the digester. It was noticed that when no form of stirring takes place inside the digester, a temperature gradient forms due to the natural convection phenomenon. The presence of this gradient is undesirable in most anaerobic digestion applications, since it would cause the anaerobic bacteria to suffer from upsetting temperature changes, triggering a noticeable slowdown and even a failure of the process. As stirring would fix this temperature gradient issue, an alternative low-cost solution is investigated in this study. This potential solution manifests in changing the placement of the solid waste layer inside the liquid recirculation digester to allow it to always be at an optimal temperature. Experiments and simulations have been conducted to better understand the thermal behavior of the digester, then a model was developed and validated to numerically simulate the observed phenomena. It was concluded that the occurrence of this gradient is independent of the contents of the digester, while in the same time it was established that the optimal location for the solid waste layer is between the heating elements.","PeriodicalId":6671,"journal":{"name":"2019 7th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"228 2","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91479510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
