Basic Info
Model No.: HZ111
Product Description
SMR catalyst have more reasonable outer appearance structure to improve strength and outer surface area,
more reasonable micro pore structure to improve the effective utilization of inner surface area. Adding rare earth as promoter to advance catalyst
activity at low temperature and anti-carbon formation ability.
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. Based on our experience, we are able to guarantee that 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. HZ111 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
SMR catalyst
It adds rare earth to improve catalyst‘s comprehensive performance. Adding rare earth can increase 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 sizes,
and usually activity can be completely recovered.
Long service life
SMR catalyst contains stable calcium aluminate support, and it can resist nickel and alumina into nickel-aluminium spinel. So it can give
additional operational security in case of frequent start-up and shut-down conditions (repeating oxidation and reduction process). Long
mechanism life and good carbon and sulphur resistance can extend catalyst service life. At present, catalyst service life is normally 3-5 years.
