Title: Inventor Zaiting Li: A Pioneer in Catalytic Conversion Technologies

Introduction

Zaiting Li, an accomplished inventor based in Beijing, China, is recognized for his significant contributions to the field of catalytic conversion processes. With a total of four patents to his name, Li is a prominent figure in the development of innovative methods for transforming petroleum hydrocarbons into valuable chemical products.

Latest Patents

Li's most recent innovations include two notable patents focusing on catalytic conversion processes. The first patent describes a method for producing light olefins with a high yield from petroleum hydrocarbons. This process involves contacting a pre-heated feedstock with a specialized catalyst that combines phosphorus and transition metal modified silica-rich zeolite with a pentasil structure in either a riser or fluidized bed reactor. Under catalytic conditions, the hydrocarbons convert to produce a reaction effluent and a spent catalyst, which are then separated for further refinement into liquid and gaseous products such as ethylene and propylene.

The second patent relates to the catalytic conversion of hydrocarbon feedstock aimed at producing isobutane and isoparaffin-enriched gasoline. This process employs two distinct reactions, where preheated feedstock is combined with hot regenerated catalyst in a reactor's lower part. As a result, catalytic cracking occurs, followed by isomerization and hydrogen transfer reactions. The final products include LPG with an isobutane content ranging from 20 wt% to 40 wt%, along with gasoline having isoparaffin content between 30 wt% to 45 wt% and olefin content below 30 wt%.
