Overview

The 500l high-pressure hydrogenation kettle is suitable for large-scale and continuous production and has important industrial applications. For example, acetylene and propyne in petroleum cracking gas can be partially hydrogenated by palladium catalysis to produce high-purity ethylene and propylene. In the oil and fat industry, liquid oil is hydrogenated into solid or semi-solid fat to produce hardened oil for artificial butter or soap industry.

Product Details

500l high-pressure hydrogenation kettleIntroduction:

The key to catalytic hydrogenation is the catalyst. They can be roughly divided into two categories:

1. Low pressure hydrogenation catalysts mainly consist of highly active Raney nickel, platinum, palladium, and rhodium. Low pressure hydrogenation can be carried out at 1-4 atmospheres and lower temperatures;

2. High pressure hydrogenation catalysts are mainly active materials such as Raney nickel and cuprous chromate. High pressure hydrogenation is usually carried out at temperatures between 100 and 300 atmospheres. Nickel catalysts are widely used, including various types such as Raney nickel and nickel boride. The characteristic of precious metal platinum and palladium catalysts is high catalytic activity, and their dosage can be much less than nickel catalysts. When platinum is used as a catalyst, most of the ene bonds can be reduced under conditions below 100 ℃ and atmospheric pressure.

Most industries use platinum and palladium as carriers, and those using activated carbon as carriers are called platinum carbon and palladium carbon, respectively. Copper chromite Cu (CrO2) 2 has a low cost and is widely used in industry. Its characteristic is that it is particularly effective in catalyzing carbonyl groups, and has high catalytic ability for ester groups, amides, imides, etc. It has low activity for alkene and alkyne bonds, and is basically inactive for aromatic rings.

500l high-pressure hydrogenation kettlePurpose:;

Catalytic hydrogenation is suitable for large-scale and continuous production and has important industrial applications. For example, acetylene and propyne in petroleum cracking gas can be partially hydrogenated by palladium catalysis to produce high-purity ethylene and propylene. In the oil and fat industry, liquid oil is hydrogenated into solid or semi-solid fat to produce hardened oil for artificial butter or soap industry.

Palladium carbon is dissolved in ethanol and vacuum drawn into a high-pressure reactor or poured into the reactor. Then, ethanol is added to wash the container before being put into the reactor. After the reaction is complete, the material is filtered to recover palladium carbon. The reactor can be washed with reaction solvent and palladium carbon can be recovered through the filter.
