Title: Innovations of Chengli Liu in Hydrocarbon Processing

Introduction

Chengli Liu is a notable inventor based in Hunan, China, recognized for his contributions to hydrocarbon processing technologies. He holds 2 patents that focus on innovative methods for hydrotreatment, enhancing the efficiency and effectiveness of hydrocarbon oil processing.

Latest Patents

One of his latest patents is the "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 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 without the need for recycle hydrogen or associated devices. The resulting reformate achieves a bromine index of below 50 mgBr/100 g, with an arene loss of less than 0.5 wt %.

Another significant patent is the "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 technique enables rapid and efficient dispersion of hydrogen into the hydrocarbon oil, achieving a stable hydrogen-rich product with hydrotreating effects that are equivalent to or surpass existing methods.
