Latest Patents

Raichi Zhang holds a patent for a catalytic conversion process designed to produce isobutane and isoparaffin-enriched gasoline. This process involves two distinct reactions, where preheated hydrocarbon feedstock is contacted with hot regenerated catalyst in the lower part of a reactor. The catalytic cracking reaction occurs, leading to a mixture of vapors and coke-deposited catalyst that up-flow into a suitable reaction environment. This results in isomerization and hydrogen transfer reactions. The produced liquefied petroleum gas (LPG) contains an isobutane content of approximately 20 wt % to 40 wt %, while the gasoline produced has an isoparaffin content of about 30 wt % to 45 wt % and an olefin content of less than 30 wt %. The research indicates that the Research Octane Number (RON) and Motor Octane Number (MON) of the gasoline range from 90 to 93 and 80 to 84, respectively.
