Biofuels Production

Manufacturing of bioethylene via dehydration of bioethanol is an alternative to the fossil-based ethylene production and decreases the environmental consequences for this chemical commodity. A few industrial plants that utilize 1st generation bioethanol for the bioethylene production already exist, although not functioning without subsidiaries. However, there is still no process producing ethylene from 2nd generation bioethanol. This study is divided into two parts. Different ethanol and ethylene production methods, the process specifications and current technologies are briefly discussed in the first part. In the second part, a techno-economic analysis of a bioethylene plant was performed using Aspen plus and Aspen Process Economic Analyzer, where different qualities of ethanol were considered. The results show that impurities in the ethanol feed have no significant effect on the quality of the produced polymer-grade bioethylene. The capacity of the ethylene storage tank significantly affects the capital costs of the process.

Chemoselectivereduction of the C=Cbond in avariety of a,b-unsaturatedc arbonylc ompounds using supported palladium nanoparticles is reported.T hree differenth eterogeneous catalysts were compared using 1a tm of H 2 : 1) nano-Pd on am etal-organic framework (MOF:P d 0 -MIL-101-NH 2 (Cr)), 2) nano-Pd on as iliceous mesocellularf oam (MCF:P d 0 -AmP-MCF), and 3) commerciallya vailablep alladium on carbon( Pd/C). Initials tudies showed that the Pd@MOF and Pd@MCF nanocatalysts were superior in activity and selectivity compared to commercial Pd/C. Both Pd 0 -MIL-101-NH 2 (Cr) and Pd 0 -AmP-MCF werec apable of delivering the desired products in very short reaction times (10-90 min) with low loadings of Pd (0.5-1 mol %). Additionally, the two catalytic systems exhibited high recyclability and very low levels of metal leaching.
