According to the technical literature, so far no comprehensive study has been performed on MSW dryers considering with the actual components of the waste and the moisture content above 40%. Here a comprehensive study for wet MSW dryers consists of three different parts is performed. In the first part, a semi-theoretical mathematical model is developed to calculate the drying rate (internal) of wet MSW. For this purpose, with the laboratory results in the technical literature and Statistica software, a suitable mathematical model for drying MSW is validated and determined. Then, the external drying rate is determined according to the type of dryer selected and after its validation; it is compared with the internal drying rate. In the second and third parts, after validation of EES developed code, energy and exergy analysis are reviewed and finally parametric study is performed to investigate the effects of different parameters on energy and exergy efficiencies of unsorted wet MSW drying process. The results show that the best model for drying the unsorted MSW is the logarithmic model with a corresponding R^2 of 0.999. The internal and external evaporation rates are 0.157 and 0.165 kg/s and it is seen these two rates are well matched together and differ by only 5%. The energy efficiency and exergy efficiency of the dryer are 13.92% and 2.91%, respectively. According to the parametric study, the inlet air temperature and the temperature of inlet MSW have the greatest effect on energy efficiency, respectively. Inlet air conditions such as absolute humidity of inlet air and atmosphere pressure have the greatest effect on the exergy efficiency of MSW drying.","PeriodicalId":14572,"journal":{"name":"Iranian Journal of Chemistry & Chemical Engineering-international English Edition","volume":"38 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2021-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81127996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A new method was proposed to analyze the effect of nitrogen deposition on Soil emission during freeze-thaw cultivation.On this basis, the contents of soil temperature, moisture, inorganic nitrogen and soluble carbon were determined. Three freeze-thaw models of nitrogen deposition levels were established. The influence of nitrogen deposition on Soil emission and the effect of nitrogen deposition on emission in alpine wetland were studied by multivariate variance analysis. The effect of nitrogen deposition on emission of alpine wetland was studied. The results showed that different soil temperature and moisture content had great influence on the seasonal variation of soil flux, which was generally consistent with the single peak of soil temperature, but highly consistent with the variation of soil moisture content in different growth periods. Nitrogen treatment changed the DOC content of soil organic matter. DOC content in mineral layer and organic layer increased significantly in low and medium nitrogen treatments. The emission of soil in freezing period is lower than that in normal temperature period, and that in multiple freezing period is less than that in one freezing period. The emission rate of soil under freeze-thaw condition is the smallest, and the emission rate of soil after thaw is the largest. Appropriate nitrogen deposition can promote soil emission, while high nitrogen deposition can inhibit emission.","PeriodicalId":14572,"journal":{"name":"Iranian Journal of Chemistry & Chemical Engineering-international English Edition","volume":"38 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2021-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87448530","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This rise in demand is connected to the growing environmental concerns over the extensive use of synthetic and non-biodegradable plastic packaging and the dumping of plastics waste in landfills. Biodegradable bioplastics are polymers that are mineralized into carbon dioxide, methane, water, inorganic compounds, or biomass by specific microorganisms by enzymatic action. As a result, they could be a viable and environmentally friendly alternative to petrochemical plastics. Bioplastic delivers precisely as per demand exhibiting several advantages: lower carbon footprint, energy efficiency, non-hazardous, stable, cost-efficient and eco-friendly. Herein, a major focus is given on the discussion of the bioplastics production from various sources, their type and the role of additives to strengthen their chemical and physical properties. This review article goal to provide information about the bioplastic synthesis concerning the recycling of bioplastics, thermoplastic biocomposites and their blends with a special focus on mechanical recycling of bio-based materials.

The effect of pH, adsorbent dosage (dose), initial MB dye concentration (C0) contact time (tc) and temperature (T) on the removal percentage (Ad%) of MB dye onto NiO-SiO2NPs was studied and the optimum value of each factor was determined (pH=7, dose=0.1g, C0=30 mg/L, tc=15 min and T=298.0 K).

Kinetics experiments were performed to investigate the adsorption kinetics, the pseudo-second-order kinetics coincided quite with the kinetic results. The thermodynamic behavior of the adsorption process was studied by considering the effect of temperature on the adsorption capacity, where the results showed that the process is spontaneous (∆G, Ad 0<0) at used temperature range and exothermic (∆H, Ad 0<0) with ∆S, Ad 0<0.

SiO2, Al2O3, ZnO and MnO were utilized to compose with green synthesized TiO2 nanoparticles for this purpose. The samples were recognized by XRD, FT-IR, DLS and SEM. Also, the cytotoxicity and antibacterial activity were assessed. DFT computation was performed to identify the connected energy and band gap energy of nanocomposites by B3LYP/Lan2DZ quantum approach. TiO2/Al2O3 showed a lower size and the lowest agglomeration than synthesized TiO2 and other nanocomposites. Furthermore, all samples indicated strong antibacterial activity against investigated bacteria due to cell death caused by membrane permeability increase and bacterial wall integrity disruption. Nanostructures has cytotoxicity with low level on A172 cells. The only exception is TiO2/ZnO which indicated a potent index of cytotoxicity on the cancerous cell lines as demonstrated by low IC50 value of 50 ppm.

A complementary approach which is a combination of model free isoconversional methods and model fitting methods was carried out to achieve more accurate results for the kinetic parameters. Moreover, Arrhenius parameters were determined by non-isoconversional Kissinger’s method. The values of the self-accelerating decomposition temperature (TSADT)and the critical ignition temperature (Tb) were also calculated. The results indicated that PBXW-108, a plastic bonded explosive, in comparison to H6 and A4 has the highest pre-exponential factor and activation energy of decomposition. Moreover, TSADT and Tb of PBXW-108 are higher than those of A4 and H6. Therefore, PBXW-108 can be introduced as a safer alternative to traditional A4 and H6 explosives.
