Nickel Catalyst As Ammonia Decomposition Catalyst

Product Overview

Description

Nickel Catalyst As Ammonia Decomposition Catalyst

 

Ammonia decomposition catalyst is a kind of sec. reaction catalyst, based on the nickel as the active component with alumina as the main carrier. It is mainly applied to ammonia plant of secondary reformer of hydrocarbon and ammonia decomposition

device, using the gaseous hydrocarbon as the raw material. It has good stability, good activity, and high strength.

 

Application:

It is mainly used in ammonia plant of secondary reformer of hydrocarbon and ammonia decomposition device,

using the gaseous hydrocarbon as the raw material.
