Mulch films increase soil temperature, maintain moisture, improve water and fertilizer absorption, reduce weed growth. This work studied a mulching film made using polyvinyl alcohol (PVA) lignin extracted from empty fruit bunches (EFBs). The mulch were investigated for opaqueness, biodegradation, water-solubility, mechanical properties. Life cycle assessment (LCA) cost estimate analysis conducted. composite film-PVA solution was blended with 6% EFB in dimethyl sulfoxide (DMSO) five different...
The results of the interviews indicate that it was difficult for interviewed actors to explain how tasks and responsibilities differed between CAB; Regional Energy Agency; Cooperation Council; representatives these three bodies also experienced this difficulty. CAB’s leading role in energy strategy work accepted by other stakeholders; but only because regional currently lacked resources take on such work. In future; Councils will be main legitimate CAB competitors; willing over strategic
Catalytic behavior of La2O3 promoted SO42−/ZrO 2 (SZ) in the simultaneous esterification and transesterification palm oil with 10 wt% myristic acid was studied. (90 purity) derived from domestic monazite ore introduced into SZ by impregnation method. Effects loading reaction parameters on conversion were also investigated. The 20 wt%La2O3-SZ catalyst possessed dual strong basic sites which could efficiently promote both reactions. Using catalyst, initial rate reactions faster, equilibrium...
The wastewater of a petroleum processing facility was used to grow the oleaginous bacterium Rhodococcus opacus PD630 produce microbial oils. Undiluted supplemented with molasses (20 g/l) and ammonium chloride (1 provided maximum dry biomass concentration nearly 6 g/l in 96 h batch culture. lipid bacterial broth exceeded 3 content 52% by weight. Biomass oil production were further improved using 96-h fed-batch fermentation instead final 7.2 4 g/l. 54% yield on sugars 0.33 g/g. lipids similar...
Sugarcane trash (SCT) is a promising, underutilized raw material for producing value-added bio-based materials. Nanocrystalline cellulose (NCC) production conditions were obtained from the experiment. On other hand, bioethanol retrieved secondary data. This study compared environmental impact of SCT in NCC to that bioethanol. For production, was subjected organosolv pretreatment (140, 160, or 180 °C) mixed solvent system (methyl isobutyl ketone (MIBK), ethanol, and water), bleached, then...
Hydrogen has been recognized as an alternative energy carrier and one of the future fuels in global transition to clean energy. production with net-zero-carbon emissions developed because steam methane reforming, a conventional means hydrogen production, involves carbon dioxide emissions. This study carried out life cycle impact assessment compared outcomes two other zero-carbon emission technologies: proton exchange membrane electrolysis pyrolysis. Main inventory data collection was based...
Oil palm empty fruit bunch and trunk are classified as primary lignocellulosic residues from the oil industry. They considered to be promising feedstocks for bioconversion into value-added products such bioethanol. However,using these materials produce bioethanol remains a significant challenge small medium enterprises. Hence, techno-economic sensitivity analyses of plant simultaneously treating were performed in this study. The information based on preliminary experimental data batch...
Lignin was extracted from sugarcane bagasse using alkali treatment process. The antimicrobial activity of lignin (LNB) evaluated against two pathogenic bacteria, Sta phylococcus aureus and Escherichia coli by broth dilution method. MIC MBC values LNB are 10,000 μg/ml 20,000 μg/ml, respestively in both bacteria. composite film between polyvinyl alcohol (PVA) polyvinylpyrrolidone (PVP) blending with at five different amounts (1%, 3%, 5%, 10% 15%) were produced solvent casting. chemical...
Importance of the work:A new approach was investigated using acid oil from acidulation for its economic feasibility in biodiesel production.Objectives: To investigate esterification conditions production oil, and conduct process simulation cost investigation ASPEN software.Materials & Methods: Reaction time (1-6 h) methanol-to-oil molar ratio (20:1-30:1) were varied with a fixed 4% H 2 SO 4 catalyst at, 60 °C 500 revolutions per minute.Based on experimental data, optimized determined...
Abstract Trisodium phosphate (TSP) is a non‐toxic waste obtained from alkaline cracking as part of the processing monazite ore. After simple purification, TSP can be utilized in many applications; however, it used catalyst this study. It characterized using Thermogravimetric analysis , X‐ray diffraction analysis, Brunauer‐Emmett‐Teller, and Temperature‐programmed desorption carbon dioxide optimized transesterification reaction. recrystallization calcination at 350 °C for 0.5 h, form was...
