Biodiesel and the blends were tested in 4-cylinders, 4-strokes and direct injection diesel engine to investigate the emissions and performance at engine speeds of 600-3000 rpm under idle and full load. The result was compared to the data of petroleum diesel. The experimental data showed that the emissions of biodiesel and blends were much lower than B100. In comparison, the emission of biodiesel was more than 50% lower than B100. The average reductions were 76.19% for smoke opacity; and 97.62, 90.36 and 98.69% for brake specific emission factors of BS-HC, BS- CO and BS-SO , respectively. The engine 2 performances were also observed. Results showed that when WCOME were used both BHP and BMEP showed slight reductions about 8.63% compared to diesel. However, higher fuel consumption, had been indicated by the BSFC. The BSFCs of B100 were recorded to be 9.45% higher than biodiesel.

Three samples were taken per week in three months by Bailenger method with concentration-flotation on 33 percent zinc sulphate was applied. Slide was prepared and observed under a microscope. Cyst count was done by Mac Master Slide. The average parasites in influent and effluent samples of Imam Hospital was 8.53 and 13.83 per liter, respectively. The Nematode larva with the highest number of 4.78 per liter from the influent and Oocyst with 7.81 per liter of the effluent of the system were determined. Similarly, in Boali Hospital the Nematode larva in influent and Oocyst in effluent were 9.06 and 10.97 per liter, respectively. Nematode larva with 5.97 and of Entamoeba histolytica with 4.12 ranked the highest number.

Hence, most countries have begun to realize that the need for sustainability in energy production and consumption is significantly vital. Therefore, tracking the progress of sustainability is essential. The aim of this paper is to present a set of indicators for Iran, based on the Helio International Sustainable Energy Watch (SEW) indicators, that shows how to track progress toward sustainability in the energy sector. Due to SEW framework, Iran is the closest to sustainability target based on indicators for access to electricity. Iran performs worst on the indicators for CO emissions and energy intensity. Iranian's private sectors had already signed 2 contracts to build plants (more than 600 MW) based on biomass systems and newly developed wind energy (500 MW). Based on Iran Renewable Energy Organization (SUNA) remarks the private sector has submitted a proposal for generating 3000 MW. The objective of present work is to highlight fundamental challenges about the development of renewable energy and policy framework requirements for achievements of sustainable energy in Iran.","PeriodicalId":14591,"journal":{"name":"iranica journal of energy and environment","volume":"104 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75908352","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}

Organic matter solubilization of alkaline and acid pretreatments were increased up to 28 and 15.7% of initial soluble COD in POME, respectively. That corresponds to carbohydrate solubilization of 41 and 32% of initial soluble carbohydrate in POME, respectively. A maximum hydrogen production yield of 4.6 l H /l-POME was achieved 2 from POME pretreated with 1.5% w/v NaOH, which was 3-fold greater than raw POME and 1-fold greater than POME pretreated with 1.5% w/v HCl. Optimum conditions for biohydrogen production from alkaline pretreated POME using Thermoanaerobacterium-rich sludge was found at initial pH 5.5 and temperature of 60°C, which gives a maximum hydrogen production yield of 5.2 l H /l-POME and increased 51% as compared to raw POME. 2 The biogas was mainly composed of hydrogen and carbon dioxide with the percentage of hydrogen ranging from 55-60% of biogas and free of methane. During the conversion of alkaline pretreated POME into hydrogen, the acetic and butyric acids were main by-products in the metabolism. The results showed that alkaline pretreatment is an effective pretreatment methods for enhancing the hydrogen production yield from POME. The use of Thermoanaerobacterium-rich sludge is promising for future engineering practice of biohydrogen production from alkaline pretreated POME.","PeriodicalId":14591,"journal":{"name":"iranica journal of energy and environment","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84952915","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}
