A comprehensive study of product distributions and coke deposition during catalytic cracking of vacuum gas oil over hierarchical zeolites
TL;DR: In this article , the authors used zeolites (Z) as catalysts in the cracking of a Colombian vacuum gas oil (VGO), with a focus on product distribution and coke deposition.
Journal ArticleDOI
Impact of the Non-Uniform Catalyst Particle Size on Product Selectivities in Consecutive Reactions
TL;DR: In this article , the analysis of consecutive irreversible reactions A→B→C in porous catalyst particles, where the simultaneous processes of diffusion and chemical reactions take place and both reactant and products are subjected to diffusion limitations, was performed for catalyst particles with non-uniform sizes.

Interpretation of Measurements in Experimental Catalysis
P.B. Weisz,C.D. Prater +1 more
TL;DR: In this article, the most frequent problem in the study of heterogeneous catalysis is the determination of a quantity called "catalyst activity", the experimental procedures, and methods of interpretation leading to a proper description of this quantity.

Reaction Rates and Selectivity in Catalyst Pores
TL;DR: In this paper, the physical picture of the pore structure, the mechanism of transport in catalyst pore, and physical factors determining reaction rates on porous catalysts are discussed, and a large number of interesting deductions are possible.
