The liquefaction of sugar cane bagasse in supercritical ethanol, with or without various proportions water as a proton donor, was conducted batch reactor to evaluate the optimal conditions for bio-oil production. following variables were studied: temperature, initial H2 pressure, and catalyst type (FeS, Fe2S3/AC, FeSO4). For noncatalytic using ∼100% (v/v) high oil yield 59.6% (daf) biomass conversion 89.8% obtained at 330 °C under pressure 4.93 MPa. catalytic presence FeSO4 same conditions,...
This work sought to improve the toughness and thermal stability of poly(lactic acid) (PLA) by incorporating poly(butylene succinate) (PBS) wood flour (WF). The PLA/PBS blends showed a PBS‐dose‐dependent increase in impact strength, elongation at break, degree crystallinity, compared PLA, but tensile Young's modulus, flexural strength were all decreased with increasing PBS content. Based on optimum 70/30 (w/w) blend was selected for preparing composites five loadings WF (5–30 phr). PLA/PBS/WF...
Abstract The grafting of the methyl methacrylate (MMA) monomer onto natural rubber using potassium persulfate as an initiator was carried out by emulsion polymerization. macroradicals reacted with MMA to form graft copolymers. morphology grafted (GNR) determined transmission electron microscopy and it confirmed that copolymerization a surface‐controlled process. effects concentration, reaction temperature, time on conversion efficiency were investigated. GNR solvent‐extraction technique....
Abstract Effects of cumene hydroperoxide (CHPO)/tetraethylene pentamine (TEPA), tert ‐butyl (TBHPO)/TEPA, and potassium persulfate (K 2 S O 8 )/sodium thiosulfate (Na 3 ) redox initiator on methyl methacrylate (MMA) grafted natural rubber by emulsion polymerization were investigated. The optimum reaction condition for each the grafting was studied. poly(methyl methacrylate) (PMMA) stays surface particles. CHPO dissolves very well in oil phase TBHPO moderately phase, K /Na initiation is...
Removal of organic sulfur compounds by using an adsorption process was carried out at ambient temperature and pressure. FAU zeolites, including NaY, HUSY cation-exchanged with metal ions such as Cu, Ni, Zn, La, have been applied adsorbents in the desulfurization model real transportation fuels. The results showed that type ion-exchanged, amount structure zeolite important roles removal each sulfur. LaNaY, LaHUSY, CuNaY possessed highest capacity toward thiophene (TH), benzothiophene (BT),...
