Catalyst

The main operational factors affecting the catalytic hydrogenation process in practice are the reaction temperature, reaction pressure, hydrogen to oil ratio, reaction air velocity, catalyst activity,

Hydrocracking is a process unit that combines catalytic reaction technology, refining technology and high-pressure technology. The selection of the process flow is related to catalyst performance, fee

Modern reforming catalysts consist of a basic active component (e.g. platinum, palladium, iridium, rhodium), a co-catalyst (e.g. rhenium, tin etc.) and an acidic carrier (e.g. γ-Al2O3 containing halog

Solid catalysts are prepared in many ways, generally through three steps: First, the selection of raw materials and the preparation of raw material solutions, the selection of raw materials must take

The isomerization process is the transformation of light n-alkanes into the corresponding isomeric alkanes. Isomerization process can be used for the production of isomerized oils, which are high-octa

The quality of crude gasoline mainly controls the final distillation point, and the final distillation point of crude gasoline is qualified to ensure the final distillation point of stable gasoline is

The development of methanol catalysts is the cornerstone of the methanol synthesis industry and can be divided compositionally into four categories: zinc-chromium based catalysts, copper based catalys

In normal operation, in order to keep the plant running for a long time, in addition to reasonable adjustment of process parameters, it is necessary to understand the working performance of the cataly

C3~C12 light hydrocarbon resources (light hydrocarbons and naphtha) are important petroleum fractions, which are generally used as raw materials for steam cracking, catalytic reforming, etc. to produc

Heavy metals (iron, copper, nickel, silver, etc.), alkaline earth metals (sodium, calcium, potassium, etc.) and alkaline nitrides in the feedstock oil have the The catalyst has the ability to contamin

Anthraquinone hydrogenation catalysts mainly include two kinds of nickel catalysts and palladium catalysts. Nickel catalysts have excellent selectivity and activity and very little degradation, but th
