The study of effect of ZSM?5 additives to cracking catalysts on the yield of light olefins and propylene
Abstract
We have investigated the catalytic cracking of heavy vacuum distillate on industrial catalyst RD-DMS-PM («BASF» company) with the addition of zeolite CVM (JSC «AZKiOS» Angarsk, Russia) and special additives MOA («BASF» company) to increase the yield of olefins for growing interest to the catalytic cracking with high yield of light olefins and, above all, propylene. Additive content varied (wt.%): 10, 20, 30 and 40 for the MOA and 3, 8, 12 and 16 for CVM. Catalytic cracking was conducted on laboratory unit in flow reactor with a fixed bed reactor at 500 °С. The dependences of product composition from the number of introduced into the catalyst additives are derived It is shown that the highest yield of propylene (11,5 wt.%) is achieved with the 40 % MOA addition or 8 % zeolite CVM. Results to increase the yield of light olefins were obtained at corresponding operating conditions existing catalytic cracking unit.
