Development and Production of High Bulk Density RAG - 7A Catalyst for Enhancing Light Olefins Yield

This is a brief introduction of the research and development of RAG-7A catalyst with high bulk density for enhancing light olefins yield.High activity Semi-synthetic matrix with modified kaolin and metal oxides modified USY zeolite were involved in the catalyst manufacture.The appraisal results show that RAG-7A catalyst not only possesses ability to crack heavy oil,suitable second order cracking activity and hydrogen transfer activity,but also has good hydrothermal stability,high bulk density and can enhance light olefins yield.
