Abstract

The acid site distribution and the catalytic activity of SAPO5 MgAPO5 and CoAPO5 samples for cracking of light alkanes was studied. The acid strength of all samples was found to be similar to that of faujasites, that of CoAPO5 being somewhat weaker than that of the other samples. The catalytic activity for cracking of n-hexane and n-butane was nearly identical for most of the SAPO5 samples investigated. For n-hexane cracking, one of the SAPO5 samples also showed a significantly higher activity than the other SAPO5 samples. The catalytic activity was three times higher for CoAPO5 and MgAPO5. Their higher activity is not due to a higher strength of the acid sites, but was concluded to be caused by a higher contribution of the bimolecular cracking mechanism.
