Arthur A Chin: Catalytic conversion of NO.sub.x over carbonaceous particles. Mobil Oil Corporation, Alexander J McKillop, Charles J Speciale, Richard D Stone, May 14, 1991: US05015362 (19 worldwide citation)

Oxides of nitrogen (NO.sub.x) emissions are catalytically reduced by contacting a flue gas contain NO.sub.x with a carbonaceous substance, preferably sponge coke or coal, in the presence of a catalyst effective for promoting the reduction of NO.sub.x in the presence of such carbonaceous substances.

Arthur A Chin, Frederick J Krambeck, Stephen S Wong, Sergei Yurchak: Process for the production of tertiary alkytl ethers from FCC light naphtha. Mobil Oil Corporation, Alexander J McKillop, Charles J Speciale, L G Wise, November 24, 1992: US05166455 (14 worldwide citation)

A process has been discovered for the conversion of C.sub.5 -C.sub.7 olefinic hydrocarbons, such as those contained in FCC light naphtha, to iso-butene-rich and isoamylene-rich streams in an integrated process for the production of MTBE and TAME. The process involves the initial separation of the is ...

Arthur A Chin: Reducing NO.sub.x emissions with antimony additive. Mobil Oil Corporation, Alexander J McKillop, Charles J Speciale, Richard D Stone, January 29, 1991: US04988432 (10 worldwide citation)

A process for regeneration of cracking catalyst while minimizing NO.sub.x emissions is disclosed. A DeNOx additive is present in an amount and in a form which reduces NO.sub.x emissions, but does not passivate metals (such as Ni and V) deposited on the catalyst during the cracking reaction nor CO co ...

Arthur A Chin: Reducing NO.sub.x emissions with group IIIB compounds. Mobil Oil Corporation, A J McKillop, C J Speciale, Richard D Stone, June 4, 1991: US05021146 (10 worldwide citation)

A process for regeneration of cracking catalyst while minimizing NO.sub.x emissions is disclosed. A Group IIIB based DeNO.sub.x additive is present in an amount and in a form which reduces NO.sub.x emissions. Relatively small amounts of lanthanum or yttrium oxides, or lanthanum titanate, preferably ...

Arthur A Chin, Stephen S F Wong: Process for dimerizing propylene and for converting hexenes into ethers. Mobil Oil Corporation, Alexander J McKillop, Dennis P Santini, Laurence P Hobbes, July 18, 1995: US05434327 (4 worldwide citation)

Hexenes are produced when propylene is catalytically converted under moderate conditions over chosen small pore zeolite catalysts having small 10-membered ring openings. These chosen catalysts are ZSM-22, ZSM-23, ZSM-35, and ZSM-48. They are unexpectedly effective to dimerize a substantially ethylen ...
