Patent Number Title Of Patent Date Issued
6290916 Apparatus for controlling moisture in a catalyst regeneration process September 18, 2001
A method and apparatus are disclosed for removing water from a recycle gas stream in a catalyst regeneration process. A recycle gas stream contacts catalyst and the catalyst sorbs water from the recycle gas. Some of the now-dried recycle gas recirculates to the regeneration process, ther
6153091 Method for reducing chloride emissions from a moving bed catalyst regeneration process November 28, 2000
A method is disclosed for decreasing the emissions of chlorine-containing species from a moving bed process for regenerating spent catalyst particles with a recycle gas stream. A recycle gas stream contacts spent catalyst particles at regeneration conditions, thereby producing a flue
6123833 Method for controlling moisture in a catalyst regeneration process September 26, 2000
A method and apparatus are disclosed for removing water from a recycle gas stream in a catalyst regeneration process. A recycle gas stream contacts catalyst and the catalyst sorbs water from the recycle gas. Some of the now-dried recycle gas recirculates to the regeneration process, ther
6117809 Method for decreasing chloride emissions from a catalyst reduction process September 12, 2000
A method is disclosed for recovering chlorine-containing species from an outlet stream of a zone in which the catalytic metal of a chloride-containing catalyst is reduced. The outlet stream is passed to a sorption zone which contains catalyst and which is maintained at sorption condi
6034018 Method for reducing chloride emissions from a moving bed catalyst regeneration process March 7, 2000
A method is disclosed for decreasing the emissions of chlorine-containing species from a moving bed process for regenerating spent catalyst particles with a recycle gas stream. A recycle gas stream contacts spent catalyst particles at regeneration conditions, thereby producing a flue
5965473 Cyclic catalytic hydrocarbon conversion process with reduced chloride emissions October 12, 1999
A method is disclosed for recovering chlorine-containing species from the outlet gas of a hydrocarbon conversion process with a cyclic regeneration operation. The outlet gas from an off-stream catalyst bed in which regeneration is occurring is passed to another off-stream catalyst bed
5837636 Method for reducing chloride emissions from a catalyst regeneration process November 17, 1998
A method is disclosed for decreasing the emissions of chlorine-containing species from a process for contacting catalyst particles with a recycle stream containing chlorine-containing species. Prior to contacting the catalyst particles with the recycle gas, an effluent stream that contai
4810683 Regeneration of a platinum-containing zeolite March 7, 1989
A method is described for the regeneration of a hydrocarbon conversion catalyst that has become deactivated by carbonaceous material deposition where the catalyst comprises a nonacid zeolite and a Group VIII metal component. The method comprises the steps of (1) removing a substantial
4529505 Indium-containing catalyst for reforming hydrocarbons July 16, 1985
A new catalyst for converting hydrocarbons, especially for reforming hydrocarbons, is disclosed. Also disclosed is a hydrocarbon conversion process using the catalyst as well as a method for making the catalyst. The catalyst comprises a platinum group component, a tin component, an i
4522935 Platinum and indium-containing catalyst for reforming hydrocarbons June 11, 1985
A new catalyst for converting hydrocarbons, especially for reforming hydrocarbons, is disclosed. Also disclosed is a hydrocarbon conversion process using the catalyst as well as a method for making the catalyst. The catalyst comprises a platinum group component, a tin component, an i
4487848 Indium-containing catalyst for reforming hydrocarbons December 11, 1984
A new catalyst for converting hydrocarbons, especially for reforming hydrocarbons, is disclosed. Also disclosed is a hydrocarbon conversion process using the catalyst as well as a method for making the catalyst. The catalyst comprises a platinum group component, a tin component, an i
4400571 Hydrocarbon isomerization process August 23, 1983
Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with a catalyst composite comprising from about 5 weight percent to about 95 weight percent of a silica polymorph consisting of crystalline silica, said silica polymorph after calcination in air at 600
4362653 Hydrocarbon conversion catalyst December 7, 1982
Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with a catalyst composite comprising a silica polymorph consisting of crystalline silica, said silica polymorph after calcination in air at 600.degree. C. for one hour, having a mean refractive index of
