What is quality CoMo Hydrogenation Catalyst? CoMo Hydrogenation Catalyst process

CoMo Hydrogenation Catalyst is composed of active components, additives and carriers. Its role is to remove sulfur, nitrogen, oxygen and heavy metals by hydrogenation, as well as hydrogenation saturation of polycyclic aromatic hydrocarbons. The molecular structure of the raw material in this process does not change much. According to various needs, it is accompanied by a hydrocracking reaction, but the conversion depth is not deep, and the conversion rate is generally about 10%. CoMo Hydrogenation Catalyst requires the dual functions of hydrogenation and hydrogenolysis, and the acidity required for hydrogenolysis is not high.

The mechanism of CoMo Hydrogenation Catalyst is that the hydrogen molecules adsorbed on the catalyst generate active hydrogen atoms and add ene and alkyne whose bonds are weakened by the catalyst. In the presence of Pt, Pd, Ni and other catalysts, olefins and alkynes undergo an addition reaction with hydrogen to generate corresponding alkanes and release heat, which is called heat of hydrogenation. When unsaturated hydrocarbons are hydrogenated, heat is released.

CoMo Hydrogenation Catalyst is a catalyst used in the hydrocracking process of heavy oil in the process of petroleum refining where heavy oil undergoes hydrocracking reaction at a high temperature of 360~450°C and a high pressure of 15~18MPa to convert it into gas, gasoline, jet fuel, diesel and other products. The hydrocracking process is a secondary processing process in the petroleum refining process, and the processing raw material is heavy distillate oil, or atmospheric residue and vacuum residue.
The main feature of the CoMo Hydrogenation Catalyst cracking process is its high production flexibility. The product distribution can be controlled by operating conditions. It can produce gasoline, jet fuel with low freezing point and diesel, and it can also produce tail oil as a cracking feedstock or produce lubricating oil. The resulting product has good stability, but the octane number of gasoline is not high. Due to harsh operating conditions, high equipment investment and operating costs, it is not as widely used as catalytic cracking.

However, the cracking process of CoMo Hydrogenation Catalyst can process raw materials with high content of sulfur and other impurities and aromatic hydrocarbons. The raw materials are strictly refined in the advanced hydrofining reactor before entering the cracking reactor. Depending on the target product, the feed to the cracking reactor can be recycled oil or not. The range of circulating oil is very wide, it can be all distillate oil below gasoline, or heavy distillate oil below diesel (>350℃). Most raw materials can be used in fixed-bed reactors, but fluidized bed reactors must be used in residual oil hydrocracking, and CoMo Hydrogenation Catalyst must be adapted to the corresponding raw materials, reaction conditions and equipment.
