High performance alumina heat transfer solids for high temperature fluidized bed synthesis gas reactions

摘要

A process for the production of hydrogen and carbon monoxide from a low molecular weight hydrocarbon by contact with a fluidized bed of catalyst employs particulate alumina heat transfer solids at high temperature in the presence of oxygen and/or steam. The particulate heat transfer solids are characterized by defined values of (i) peripheral surface layer Si and B, (ii) performance index, (iii) tapped bulk density and (iv) Davison Attrition Index. Sintering, agglomeration and attrition tendencies of the particles are reduced.
