Study on acid-base coupled catalytic pyrolysis of heavy crude oil to light olefins and aromatics by Py-GC/MS and fixed bed reactor

Noah Niwamanya et al.

Summary: Direct catalytic cracking of heavy crude oil is a cost-effective method for producing raw materials for the petrochemical industry. This study investigated the effects of calcium aluminate base catalysts and ZSM-5 acid zeolites on heavy crude oil conversion using the Py-GC/MS technique. The results showed that ZSM-5 with a Si/Al ratio of 40 had the highest selectivity for light olefins and BTX, while calcium aluminate (CaAl-3) had the highest selectivity for C2-C4 olefins and BTX. The Mix model of acid-base coupled catalytic pyrolysis demonstrated the best performance in terms of hydrogen transfer reactions and yield of light olefins.

Green synthesis of nano-H-ZSM-5 zeolite single-crystal aggregates via an in situ reconstruction of the topology of natural clay

Xinyu Li et al.

Summary: This study presents a unique method for the synthesis of defect-free, highly crystalline nano-H-ZSM-5 through the kinetically controlled in situ reconstruction of natural clay within a solid-state-like system. Crystal nucleation and growth were controlled by aging to achieve desired crystal size. The uniform silica-alumina property of natural clay was directly inherited by nano-H-ZSM-5, providing uniformly distributed acidic sites for catalysis. The obtained crystals showed superior performance in methanol-to-propylene conversion compared to commercial ZSM-5. This strategy promotes the development of natural silica-aluminate clay resources and allows scalable production of high-quality nano-H-ZSM-5 single crystals for heterogeneous catalysis.

Quantifying the Influence of Water on the Mobility of Aluminum Species and Their Effects on Alkane Cracking in Zeolites

Tram N. Pham et al.

Summary: The role of extra-framework Al species in zeolites in influencing important reactions like alkane cracking has been extensively discussed. Water treatments can modify the structure of zeolites and influence reaction rates, but the direct relationship between structural modifications and reactivity is not fully understood. Water can generate highly active sites for alkane cracking, but it also inhibits the cracking rate on these sites, demonstrating the complex role water plays in these reactions.
