ABSTRACT:
Porous bodies are produced which are suitable for use as supports for catalysts, including living cells, such as bacteria and which are upset resistant to acids and bases. The bodies have a significantly large average pore diameter of about 0.5 to 100 microns, (i.e. 5,000 to 1,000,000 .ANG.) and a total pore volume of about 0.1 to 1.5 cc/g with the large pores contributing a pore volume of from about 0.1 to 1.0 cc/g. The bodies are made by preparing a mixture of ultimate particles containing a zeolite and one or more optional ingredients such as inorganic binders, extrusion or forming aids, burnout agents, or a forming liquid, such as water. Incorporated into the support is activated carbon which provides improved properties. In a preferred embodiment, the ultimate particles are formed by spray drying.
