Abstract: - 1 -                     C 567 (R) Abstract of the Invention The invention relates to the field of fabric softening. It provides for fabric softening compositions comprising a relatively water-insoluble cationic detergent surfactant  and a free C8-C24 alkyl-or alkenylmonocarboxylic  acid. These compositions are significantly more storage stable than compositions, wherein the monocarboxylic is present as a soap. Further inclusion of a relatively water-soluble cationic detergent surfactant or cationic polymer sig-nificantly increases the softening performance.

Abstract: "ABSTRACT OF THE DISCLOSURE"             Reduction of CO and SOx emissions from regenerators associated with cyclical fluidized catalytic cracking (FCC) units used to convert hydrocarbon feedstocks into more valuable products is achieved by introducing particles of bastnaesite into the FCC unit.  The bastnaesite particles recycle with the catalyst particles successively through a catalytic cracking reaction zone, a stripping zone, and a regeneration zone.  The bastnaesite particles react with SOx produced in the regenera-tion zone of the FCC unit, thereby lowering the SOx content of the flue gas discharged therefrom.  in the catalytic cracking and stripping zones of the FCC unit, the bastnaesite particles are at least partially reactivated so that upon returning to the regeneration zone yet more SO2 is removed.  The bastnaesite particles also aid in lowering CO emissions from the FCC regen-erator by catalysing the reaction between CO and oxygen to yield Co2.
