World Catalyst Market Series ---- Four of the 8 Catalysts That Are Changing the World: Petroleum Refining Catalysts
Thread Content
Catalysts play a very important role in the progress of human civilization and the development of the world economy; every major breakthrough in this field has significantly transformed the ways in which humans produce and live. The emergence of each catalyst has given rise to a new industry; today we introduce four of the eight catalysts that have changed the world since the Industrial Revolution: petroleum refining catalysts.

Almost all petroleum refining processes require catalysts, including catalytic cracking, catalytic reforming, catalytic hydrogenation, alkylation, etherification, and catalytic dehydrogenation and desulfurization. Petroleum refining catalysts account for one-third of the total catalyst market share. The first catalysts used were zeolite molecular sieves, X- and Y-type zeolites; in particular, Y-type zeolites remain the main active components in catalytic cracking processes to this day. Currently, there are a wide variety of catalysts that can be used in petroleum refining, with diverse properties, such as ZSM-5, USY, Pt/AL2O3, and MoS2.
