China Energy Investment Group to Improve MTO Catalyst Regeneration and Preliminary Coke Deposition Process

摘要

The China Energy Investment Group(CEIG)could completely regenerate the deactivated methanol-to-olefin(MTO)catalyst,and the fully regenerated catalyst was exposed to C_(4) and/or C_(5)+ hydrocarbons to obtain the preliminarily coke-deposited catalyst.This catalyst upon being applied in the MTO reaction has demonstrated a lot of specific features,such as low methanol consumption,high yield of low-carbon olefins,and reasonable utilization of by-products,along with no need to control the degree of regeneration through analyzing the coke content.
