Yu Liu is a prominent inventor based in Lake Jackson, TX (US), known for his significant contributions to the field of hydrocarbon processing. With a total of 11 patents to his name, Liu has developed innovative methods that enhance the efficiency and environmental sustainability of steam cracking processes.

Latest Patents

One of Liu's latest patents focuses on methods for reducing the formation of carbon disulfide in steam cracking processes to produce olefins. This method involves passing a hydrocarbon feed that includes one or more hydrocarbons to a hydrocarbon cracking unit while also introducing sulfur-containing compounds, such as hydrogen sulfide gas. The process is designed to maintain a molar concentration of elemental sulfur in the hydrocarbon cracking unit between 10 ppm and 200 ppm. The resulting cracker effluent is then treated with a quench fluid to produce a cracked gas and a first pygas, which has a carbon disulfide concentration of less than 50 ppmw.

Another notable patent by Liu pertains to operating acetylene hydrogenation units in integrated steam cracking and fluidized catalytic dehydrogenation systems. This method separates a cracked gas from a steam cracking system and an FCDh effluent into a hydrogenation feed and an acetylene-depleted stream. The hydrogenation feed contains hydrogen, CO, and acetylene, with at least 20% of the CO sourced from the cracked gas. The process aims to hydrogenate acetylene in the feed to produce a hydrogenated effluent, optimizing the conditions for CO production during steam cracking.
