Introduction and application of Hydrocarbon Steam Reforming Catalyst |Hydrocarbon Steam Reforming Catalyst

Steam reforming of natural gas is the most common method, also known as Steam Methane Reforming (SMR), which is the most economical method to produce commercial bulk hydrogen used in the industrial synthesis of ammonia and other chemicals widely. DZC-28Q catalyst is used to catalyze the reaction of methane and steam at high temperature and pressure to produce synthesis gas (H2 and CO).

The reaction is summarized as below:

C4H10→CH4

C3H8→CH4

C2H6→CH4

CH4 + H2O ⇌ CO + 3H2

CO + H2O ⇌ CO2 + H2

Good mechanical strength

The catalyst's sponge micro pore structure can make it better tenacity so that it is of better heat-expansion & cold-shrink resistance. The 6-holed shape ensures symmetrical stress patterns and no easy fracture-line. In addition, the increase of pressure drop due to catalyst attrition or breakage will be less than 10% over guarantee period.

High activity

The reaction normally takes places at outer surface of the catalyst, therefore a uniform nickel coating has

to be insured. The catalyst features an optimized Ni-content, specially adapted to its surface roughness and

porosity. Simultaneously, domed shape allows full utilization of surface.

Excellent anti-accident ability

The catalyst has added rare earth to improve its comprehensive performance, and rare earth can increase the catalyst's adsorption capacity to water and also improve its activity at low temperature. Thus this will allow steam/carbon ratio of as low as 2.0 without risk of carbon formation. In the unlikely event of a plant up-set which does result in carbon formation, the catalyst can be easily steamed due to large hole size, and usually activity can be completely recovered.

Long service life

The catalyst contains stable aluminum aluminate support, which can resist nickel and alumina into nickel-aluminium spinel. Therefore it can give additional operational security in case of frequent start-up and shut-down conditions (repeating oxidation and reduction process). At the same time, long mechanism life and good carbon and sulphur resistance can extend catalyst service life.

Package of Hydrocarbon Steam Reforming Catalyst |Hydrocarbon Steam Reforming Catalyst

The catalyst is packed in iron barrels lined inside with plastic bags.

It should be stored in dry and well-ventilated place.

The catalyst can usually be stored for several years without remarkable deterioration in its properties.
