Abstract: Stretched fibers or fibrils from single-cell dopes are prepared by extruding the dope into a moving coagulating bath wherein the fluid motion of the bath causes the extrudate to gradually stretch. The resultant stretched fibers are useful as textured food products.

Abstract: A cyclic, fluidized catalytic cracking process providing reduced emissions of noxious effluents in regeneration zone flue gases is operated with homogeneous or non-homogeneous, regenerable, fluidized, solid particles which are circulated throughout the catalytic cracking process cycle and which comprise (1) a molecular sieve-type cracking catalyst, comprising a cracking catalyst matrix containing crystalline aluminosilicate distributed throughout said matrix and (2) a metallic reactant which reacts with a sulfur oxide to form a metal- and sulfur-containing compound in the solid particles. The method involves regeneration of the cracking catalyst in the presence of a metallic oxidation promoter which can also be a component of the solid particles.

Abstract: A cyclic fluidized catalytic cracking process is operated with a cracking catalyst which is modified with one or more metal oxides capable of reacting with sulfur oxides in the regeneration zone wherein the catalyst is regenerated under conditions which result in substantially complete conversion of carbon monoxide to carbon dioxide. Tail gases and flue gases from refinery furnaces which contain carbon monoxide and sulfur oxides are conveyed to the regeneration zone where they are scrubbed by the modified catalyst. The sulfur oxides are absorbed and the carbon monoxide is converted to carbon dioxide in the regeneration zone.
