Title: The Innovations of Li Yuansheng

Introduction

Li Yuansheng is a notable inventor based in Fushun, China. He has made significant contributions to the field of petroleum engineering, particularly in the area of hydrocracking technology. With a total of 2 patents, his work has advanced the methods used in processing heavy oil and residuum.

Latest Patents

Li Yuansheng's latest patents focus on the development of a dispersing-type catalyst for catalytic hydrocracking of heavy oil and residuum. This invention discloses a catalyst that comprises 2 to 15 wt % Mo, 0.1 to 2 wt % Ni, and 0.1-3 wt % P. The preparation method involves dissolving oxides or salts of metals such as Mo and Ni in water. The hydrocracking process includes mixing the heavy oil and residuum feedstock with the catalyst, heating the mixture, and introducing it into a suspension bed reactor. The hydrocracking reaction is performed at temperatures between 380-460°C under hydrogen pressure of 10-15 MPa. The catalyst is added in an amount to provide 150-1500 ppm of active metals, resulting in a yield of light oil exceeding 70 wt %, with minimal coking.
