The clean gasoline production technology of M-DSO Joint Development Research Institute of Fushun Petrochemical Co and Chinese Petroleum Petrochemical Research Institute of petroleum China independent intellectual property rights, in Xinjiang Taxinan Petrochemical 80 thousand tons / year catalytic gasoline hydroupgrading device to drive a success. This is the successful application of this new technology following the successful use of the Ukrainian petrochemical, the successful application of the second sets of industrial equipment.

M-DSO technology is to reduce the sulfur content of catalytic gasoline at the same time, through aromatization (or isomerization reaction) to olefin transformation into aromatic hydrocarbons (or isoparaffin) key technology of reducing olefin hydrogenation desulfurization process for the octane value of clean gasoline production losses. Through the selective hydrogenation desulfurization technology development, hydroupgrading technology and research, research and development of raw materials adaptability combination technology, the selective hydrogenation desulfurization technology and hydroupgrading technology organically, to solve the single selective hydrodesulfurization process high sulfur in FCC gasoline or bring to the ultra deep desulfurization of ultra low sulfur clean gasoline production the octane number loss of technical difficulties, the desulfurization and olefin reduction while preserving octane number, and provides technical support for the upgrading of the quality of domestic refinery gasoline upgrading.

In order to ensure that the technology is successfully put into use, Fushun Petrochemical Research Institute and partners to carry out a lot of preparatory work. According to the characteristics of the southwest tower device, with several device technical personnel exchanges and demonstration, developed a device feasible construction program, strictly follow the “safety first, environmental protection first, quality first, long-term and stable operation of the principle of” scientific and technical backbone started from technical service team, from the catalyst loading, drying, curing, passivation to the early operation of all links are in strict accordance with the procedures, the implementation of scientific research and technology from the laboratory to the popularization and application of the device, the device to achieve a smooth and orderly construction, safe and stable operation, realized the start device.

At present, Taxinan petrochemical raw materials of FCC gasoline hydrodesulfurization and modified products, in gasoline octane number loss under the condition that the sulfur content in line with the requirements of the National IV standard (50ppm). Fushun Petrochemical independent intellectual property rights of FCC gasoline hydrogenation modified FO-35M catalyst, obtained a high degree of recognition of oil refining enterprises. It is understood that this technology will soon use in Yumen petrochemical.
