Catalyst

There are many reasons for reforming catalyst deactivation (reduced activity) during the production process, such as catalyst carbon build-up, agglomeration of platinum grains and poisoning by impurit

Hydrocarbon hydrogenation is a complex reaction system in which the reactions directly interact with each other. To improve the reaction rates and product yields of various oils in the plant, correspo

Hydrocracking is the hydrogenation of hydrocarbon and non-hydrocarbon compounds under the action of a catalyst, with alkanes and olefins undergoing cracking, isomerisation and a small number of cyclis

PSA technology 1.Recovery and purification of H2 Normally, this technology should be applied during the pressure control range 0.8 to 2.5 MPa for adsorption of gases in the product. Currently, this me

The raw material for catalytic cracking units is usually heavy distillate, but currently the raw material used in some units is becoming heavier and heavier. The proportion of blended residual oil is

In the operation of the reaction regeneration , we must focus on mastering the material balance, heat balance and pressure balance of the two vessels, analyzing and judging the change trend of the pro

The 0.3Mt/a low-temperature C5/C6 isomerization device was delivered in mid-March 2014, the preparation began in April. After the completion of the device's purging, air-tight and instrument debugging

Isomerization leads to production of a compound with another atomic (group) arrangement but composition and molecular weight do not change. In literature isomerization is often called rearrangement, s

Quality control of light diesel fuel mainly refers to the freezing point and, to a lesser extent, the flash point. The control of the freezing point is to ensure that the light diesel oil has good flo

Reforming catalyst is the most important cornerstone of the whole Shidi chemical industry. The basic composition of precious metal catalyst is as follows: 1. Metal components. Precious metals such as

Basic components of a catalytic reforming plan t ，can be divided into two categories according to their production purpose: one for the production of high-octane gasoline blending components and the o
