| 585311000 | One synthesis rehabilitates catalyst for other, e.g., by alkylation with ester, etc. | 6 |
| 20080242904 | INTEGRATED ALKYLATION-ISOMERIZATION PROCESS - An integrated isomerization-alkylation process is disclosed that uses a common distillation zone. The process can comprise halogen removal. The process is suitable for the production of motor fuels from isoparaffins and olefins using solid alkylation and isomerization catalysts. | 10-02-2008 |
| 20090023966 | Treatment of Alkylation Catalyst Poisons - Alkylation processes are described herein. The alkylation process generally includes contacting an input stream including benzene with an alkylation catalyst and an alkylating agent to form an alkylation output stream including ethylbenzene. The alkylation process further includes contacting at least a portion of the alkylation output stream with a transalkylation catalyst and a benzene source to form a transalkylation output stream, wherein the benzene source is selected to minimize the amount of alkylation catalyst poisons contacting the alkylation catalyst. | 01-22-2009 |
| 20090192338 | METHOD FOR ADJUSTING CATALYST ACTIVITY - Systems and methods for producing and using one or more doped catalysts are provided. One or more coked-catalyst particles can be fluidized in the presence of one or more oxidants to provide a fluidized mixture. The coke from the one or more coked-catalyst particles can be removed to provide regenerated catalyst particles within the fluidized mixture. One or more doping agents can be distributed to the fluidized mixture, and the one or more doping agents can be deposited onto the surface of the regenerated catalyst particles to provide a regenerated, doped catalyst particle. | 07-30-2009 |
| 20100130799 | Process to Remove Dissolved AlCl3 from Ionic Liquid - Disclosed herein are processes in which precipitation permits removal of metal halides (e.g. AlCl | 05-27-2010 |
| 20100174125 | FLUIDIZED CATALYTIC CRACKER WITH ACTIVE STRIPPER AND METHODS USING SAME - A staged fluidized catalytic cracker and method for cracking a hydrocarbonaceous material includes a plurality of staged reactors that have catalyst particles flowing in series from one reactor to the next and hydrocarbon feed that is delivered in parallel to the reactors. Between each reactor the partially spent catalyst is actively stripped to partially reactivate the catalyst. Once the catalyst is fully spent in the final reactor the catalyst can be oxidatively regenerated. | 07-08-2010 |
| 20120165585 | PROCESS FOR PREPARING BENZENE FROM METHANE - The present invention relates to a process for nonoxidatively dehydroaromatizing a reactant stream comprising C | 06-28-2012 |
