The rapid separation and efficient recycling of catalysts after a catalytic reaction are considered important requirements along with the high performances. In this view, although heterogeneous catalysis is generally less if compared to homogeneous type, it preferred since benefits from easy recovery catalyst. Recycling using traditional methods such as extraction, filtration, vacuum distillati...

This work presents the recovery of biosorption supports as an alternative source of benign production of heterogeneous catalysts for oxidation reactions in mild conditions. Cr-containing FAU zeolite, in sodium form (NaY) and in proton form (HY), was recovered from biosorption studies and reused as support for the preparation of heterogeneous catalysts by the flexible ligand method, using 1,3-di...

Deactivation of heterogeneous catalysts is a ubiquitous problem that causes loss of catalytic rate with time. This review on deactivation and regeneration of heterogeneous catalysts classifies deactivation by type (chemical, thermal, and mechanical) and by mechanism (poisoning, fouling, thermal degradation, vapor formation, vapor-solid and solid-solid reactions, and attrition/crushing). The key...

Abstract In the conventional lattice percolation models, bonds or sites are open at random, whereas in reality there is often interplay of and kinetics under consideration. An interesting practically important example hydrocarbon conversion occurring a reactor containing ∼</mm...
