Producing triacetylglycerol with glycerol by two steps: Esterification and ac…
Abstract. A two-step method is proposed to obtain high selectivity and high conversion rate for producing additive triacetylglycerol of biofuel from its byproduct glycerol. The esterification of glycerol with acetic acid was carried out over resin and zeolites. Amberlyst-35 was found to be an excellent catalyst. The reaction conditions were optimized by testing catalysts, temperatures, feed…

CO2 Reforming of CH4 on Ni(111): A Density Functional Theory Calculation
CO2 reforming of CH4 on Ni(111) was investigated by using density functional theory. On the basis of thermodynamic analyses, the first step is CH4 sequential dissociation into surface CH (CH4 f CH3 f CH2 f CH) and hydrogen, and CO2 dissociation into surface CO and O (CO2 f CO + O). The second step is CH oxygenation into CHO (CH + O f CHO), which is more favored than dissociation into C and h…
