2020 CATALYST HANDBOOK INDUSTRY CATEGORIES PROCESS CATEGORIES COMPANY INDEX Olefin Catalytic Cracking (OCC) Catalyst (cont.) Economics: Since the OCC catalyst can be operated with high WHSV, the catalyst loading quantity can be reduced substantially so that the total cost of the catalyst is minimized. The OPEX of the OCC catalyst is about $11−12 for producing one ton of propylene and ethylene. Development: Proprietary and unique ZSM-5 zeolite catalysts (Figs. 2-4) were developed in 2000. The first OCC plant, which can process 60 kilotons/year of feedstock, started up in 2009. So far, four OCC plants are operating with the OCC catalyst.
