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.

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.

The catalyst 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.
