Continuous biodiesel production in a ?xed bed reactor packed with anion-exchange resin as heterogeneous catalyst
关键字：D261 anion-exchange resin Biodiesel Continuous transesteri?cation Fixed bed reactor Heterogeneous catalyst
A continuous biodiesel production from the transesteri?cation of soybean oil with methanol was inves-tigated in a ?xed bed reactor packed with D261 anion-exchange resin as a heterogeneous catalyst. Theconversion to biodiesel achieved 95.2% within a residence time 56 min under the conditions: reaction temperature of 323.15 K, n-hexane/soybean oil weight rate of 0.5, methanol/soybean oil molar ratio...

Biodiesel production from waste chicken fat with low free fatty acids by an integrated catalytic process of composite membrane and sodium methoxideq
关键字：Chicken oil Composite catalytic membrane Biodiesel Transesteri?cation Esteri?cation
An integrated process of catalytic composite membranes (CCMs) and sodium methoxide was developed to produce biodiesel from waste chicken fat. The free fatty acids (FFAs) in the chicken oil were converted to methyl esters by esteri?cation with methanol using a novel sulfonated polyethersulfone (SPES)/PES/non-woven fabric (NWF) CCMs in a ?ow-through catalytic membrane reactor. The CCM is that the N...

Selective production of poly(carbonate-co-ether) over cyclic carbonate for epichlorohydrin and CO2 copolymerization via heterogeneous catalysis of Zn-Co (III) double metal cyanide complex
Epichlorohydrin (ECH), as a cheap raw chemical material, is an ideal monomer for copolymerization with CO2 to produce biodegradable polycarbonates. This work describes the selective ECH-CO2 copolymerization via heterogeneous catalysis of nanolamellar zinc-cobalt double metal cyanide complex (Zn-Co (III) DMCC), affording a poly(carbonate-co-ether) with carbonate content up to 70.7%. Remarkably, t...
