Chemoselective decarboxylation of ceiba oil to diesel-range alkanes over a red mud based catalyst under H₂-free conditions

Abstract

Concerns over global greenhouse gas emissions such as COx and NOx as well as the depletion of petroleum fossil resources have motivated humankind to seek an alternative energy source known as green diesel.

EVA/zinc oxide nanocomposites for active food packaging: selected physical, and microbial properties

“…The amorphous phase undergoes significant changes, showing that the zinc oxide causes crystal packing of the polymer chains, finally reducing the amorphous area. The change in nanoparticle content in the composite leads to higher copolymer crystallinity, which indicates an improvement in the structural organization of EVA after the oxide addition [31][32][33]. However, the oxide content higher than 3 wt% impairs the organization of the composite and causes the formation of zinc oxide peaks.…”

Efficient and Stable Rice Husk Bioderived Silica Supported Cu2S-FeS for One Pot Esterification and Transesterification of a Malaysian Palm Fatty Acid Distillate

“…The remaining powder was rinsed with an analytical grade of ethanol and acetone. Repetition of the above procedure was then performed with the remaining loading metal concentrations (2,5,8,10,12, and 15 wt.%).…”

“…However, owing to the costly and complex separation required, homogeneous acid catalysts are unsuitable for the upscaling of commercial biodiesel manufacturing [8]. A more appropriate option is a heterogeneous acid catalyst, which exhibits chemical stability, and can be recycled; reaction products are obtained which have a high standard of purity, lack toxicity and have negligible adverse environmental consequences [9][10][11][12]. Biodiesel is commonly a domestically produced, clean-burning, renewable substitute for petroleum diesel.…”
