Title: Innovations of Qinghua Li in Hydrocarbon Processing
Introduction
Qinghua Li is a notable inventor based in Hunan, China, recognized for his contributions to hydrocarbon processing technologies. He holds two patents that showcase his innovative approaches to improving the efficiency of hydrotreatment methods.
Latest Patents
One of his latest patents is a reformate hydrotreatment method. This method involves bringing reformate and a catalyst into contact under liquid phase hydrotreatment conditions. The hydrogen used in this process is derived at least partially from the hydrogen dissolved in the reformate. This innovative approach allows for the direct hydrotreatment of reformate, effectively utilizing the dissolved hydrogen and removing olefins, while eliminating the need for recycle hydrogen and associated devices. The resulting reformate has a bromine index reduced to below 50 mgBr/100 g, with an arene loss of less than 0.5 wt %.
Another significant patent by Qinghua Li is a hydrocarbon oil hydrotreating method. This method includes injecting hydrogen into hydrocarbon oil through an opening with a nanoscale average diameter. Under liquid phase hydrotreating conditions, the hydrogen-containing hydrocarbon oil is fed into a reactor to contact a catalyst. This method efficiently disperses and dissolves hydrogen into the hydrocarbon oil without the need for a diluent or circulating oil, achieving a stable hydrogen-containing hydrocarbon oil with a high hydrogen content.
Career Highlights
Qinghua Li has worked with prominent companies in the petrochemical industry, including China Petroleum & Chemical Corporation and Hunan Changling Petrochemical Science and Technology Development Co., Ltd.
