Although pyrolysis of carbohydrate-rich biomass should theoretically yield large amounts sugar, the presence alkali and alkaline earth metals (AAEMs) in most prevents this from happening.
Commercialization of pyrolysis plastics in an inert atmosphere is challenging due to large thermal requirements. This study employs oxo-degradation and demonstrates how oxygen supplied at modest equivalence ratios can both accelerate depolymerization provide the enthalpy for without dramatically impacting desired product yields. The enthalpies high-density polyethylene (HDPE) polypropylene (PP) are measured be 2,300 ± 90 J g−-1 2,800 60 g−1, respectively. Using air as source a fluidized bed...
Abstract Industry statistics indicate that technology‐learning rates can dramatically reduce both feedstock and biofuel production costs. Both the Brazilian sugarcane ethanol United States corn industries exhibit drastic historical cost reductions be attributed to learning factors. Thus, purpose of this paper is estimate potential impact industry on emerging advanced in States. Results from study increasing biorefinery capital could significantly optimal size costs biorefineries. This...
The conversion of plastic wastes to monomeric olefins is an attractive means for achieving a circular economy. In our study, fluidized bed reactor converts post-consumer waste high-density polyethylene (HDPE) and polypropylene (PP) mostly condensed pyrolysis waxes some oils, preventing carbon loss gases. condensables were upgraded light (C2–C5) at yields greater than 76 wt % using the HZSM-5 zeolite catalyst post process that employed micropyrolyzer. These results comparable olefin monomer...
The development of catalytic transformations and processes is essential to utilize bio-oil lignin derivatives. Metal nanoparticles (M-NPs) stabilized in ionic liquids (ILs) are promising for the hydrotreatment because properties catalyst system can be customized by combining appropriate IL metal nanoparticles. Herein, we demonstrate an experimental approach stabilize lignin-derived phenolics isolated from with ruthenium NPs copolymer 1-ethyl-3-methylimidazolium acetate ([C2 C1 Im][OAc])....
