Mechanistic Insight into Heteroatom Removal from Vacuum Gas Oil Blended with PMMA or PET Waste.

This work analyzes vacuum gas oil (VGO) and hydrocracking products of this feed blended with polymethylmethacrylate (PMMA) or polyethylene terephthalate (PET) to clarify the oxygen, nitrogen, and sulfur removal pathways in these complex mixtures. Hydrocracking reactions are conducted in a semi-batch reactor with a Pt-Pd/HY bifunctional catalyst at 400 °C and 80 bar for 300 min with 10 wt % waste plastic using 0.1 catalyst/feed weight ratio.

Leaching in Specific Facets of ZIF-67 and ZIF-L Zeolitic Imidazolate Frameworks During the CO Cycloaddition with Epichlorohydrin.

Zeolitic imidazolate frameworks (ZIFs) have been profusely used as catalysts for inserting CO into organic epoxides (i.e., epichlorohydrin) through cycloaddition.
