Light Hydrocarbon Hydroisomerization Process and Catalyst Technology

Technical characteristics and application scope

This technology uses atmospheric and vacuum light naphtha, hydrocracked light naphtha, reformed topping oil and other light hydrocarbon components as raw materials, and produces low-sulfur, low-olefin, and low-aromatic hydrocarbons through hydroisomerization catalytic technology. The high-quality and clean gasoline blending component has the characteristics of low investment in equipment and high project income. It is one of the leading technologies for my country’s future gasoline quality upgrade. At present, the technology has completed industrial demonstration and has entered the stage of industrial promotion. Technical cooperation with the demander can be carried out for EPC general contracting of the project.
