SIMULATING THE OLEFIN DIFFUSION DANCE

摘要

Fossil fuels are the conventional source of chemical building blocks such as ethene and propene. A major effort has been made in the past decade to industrialize catalytic processes starting from more sustainable feedstocks. One such process is the conversion of methanol over H-SAPO-34. The zeolite catalyst H-SAPO-34 consists of large cages connected by windows decorated with Bronsted acid sites (BASs). Those cages can trap organic compounds that may assist in catalyzing methanol into olefins but may also block products from passing through the small windows.
