“…The formation of higher alcohols can be explained by the chemical interaction involving the abstracted hydroxyl radicals from biomass with the long-chain HC radicals formed from the HDPE through chain end and β-scissions and intramolecular hydrogen transfer. The presence of catalysts or high temperatures usually favored these free radical mechanisms. , The synergistic interaction between the metals and N-doped RGrO improved dehydration reactions for the transformation of alcohols to olefins. , Thus, the catalytic copyrolysis process observed less alcohol content.…”

Herein, we report N-graphitic modified transition metal nanoparticles supported on graphene as an efficient catalytic material for the production of valuable aromatics and linear αolefins via copyrolysis of wheat straw (WS) biomass and postconsumer high-density polyethylene (HDPE) waste plastic. The catalytic materials comprise transition metals (Mn, Ni, and Zn) supported on N-doped reduced graphene oxide (N-RGrO), prepared by pyrolyzing an in situ generated metal: phenanthroline complex with exfoliated graphene oxide. The catalytic performance of these materials was evaluated in pyrolysis−gas chromatography−mass spectrometry (Py-GC/MS) analysis. The catalysts had different N configurations that acted as metal anchoring sites and enhanced the basicity of the support. The effects of catalysts on the copyrolysis products of WS and HDPE with various feed ratios (100:0, 75:25, 50:50, 25:75, 0:100) were investigated. The results showed that the catalysts decreased the amount of oxygenates and increased the yield of monocyclic aromatics (MAHs) and linear α-olefins.

The reaction kinetics of deoxydehydration + hydrogenation (DODH + HG; didehydroxylation) of erythritol to butanediols and n-butane over the ReO x -Pd/CeO2 catalyst was investigated. Competitive adsorption of polyols and catalyst deactivation during the DODH + HG reaction were necessary to be considered in the kinetics. The order of the adsorption strength on the catalyst surface was erythritol >1,2-butanediol > water >1,4-butanediol and monoalcohols. The deactivation during the reaction was investigated with two models: time-dependent and conversion-dependent ones. The conversion-dependent model better fitted both the activities of reused catalysts and the time-course data. The deactivated catalysts were characterized with TG-DTA and Raman spectroscopy. The weight loss and the temperature for the combustion of deposited organic species in TG-DTA did not correlate with the deactivation degree. On the other hand, a growing signal at around 910 cm–1 was observed in Raman spectroscopy in line with deactivation, which can be explained by the formation of aggregated ReO x species. The low activity of aggregated ReO x species was supported by DFT calculations showing that the activation energy of dimeric Re2O x H y /CeO2 catalyst species for the cleavage of two C–O bonds is higher than that of monomeric ReO x H y /CeO2 species.
