Insights into Ball Milling for the Production of Highly Active Zeolites for Catalytic Cracking of VGO

P. S. Kuznetsov, V. V. Malyavin, K. I. Dement’ev

This research systematically investigates the influence of high-energy ball-milling (BM) parameters on the acidic and textural properties of zeolite Y. Among the BM parameters, the milling time (MT) exerted a more significant influence on the zeolite degradation than milling speed (MS), primarily …

Selective Production of Light Olefins from Fischer–Tropsch Synthetic Oil by Catalytic Cracking

K. I. Dement’ev, Aleksandr D. Sagaradze, P. S. Kuznetsov, Т. А. Паланкоев et autres

Biomass is a potentially unlimited source of chemicals and energy for sustainable development. However, there are currently no effective methods to produce lower olefins from biomass-derived feedstock. The catalytic cracking of synthetic oil obtained from Fischer–Tropsch synthesis to produce light olefins was …
