20090301933 | CATALYTIC REFORMING PROCESS TO PRODUCE HIGH OCTANE GASOLINE - The present invention is a multistage reforming process to produce high octane product from naphtha boiling range feed. In the process, a effluent product from a penultimate reforming stage is separated into at least a first stream and a second stream by boiling point. The lower boiling of the two streams is further reformed in a final reforming stage over a medium pore molecular sieve catalyst. | 12-10-2009 |
20090301934 | MULTI-STAGE REFORMING PROCESS TO PRODUCE HIGH OCTANE GASOLINE - The present invention relates to a multistage reforming process to produce a high octane product. A naphtha boiling range feedstock is processed in a multi-stage reforming process, in which said process involves at least 1) a penultimate stage for reforming the naphtha feedstock to produce a penultimate effluent 2) a separation step for separating the penultimate effluent into at least an intermediate stream and a heavy stream based on boiling point and 3) a final stage for further reforming the intermediate stream. | 12-10-2009 |
20100130804 | ELECTROCHEMICAL REMOVAL OF CONJUNCT POLYMERS FROM CHLOROALUMINATE IONIC LIQUIDS - A process for regenerating a spent ionic liquid catalyst including (a) applying a voltage across one or more pairs of electrodes immersed in a spent ionic liquid catalyst comprising conjunct polymer-metal halide complexes to provide freed conjunct polymers and a regenerated ionic liquid catalyst; and (b) separating the freed conjunct polymers from the regenerated ionic liquid catalyst is described. An alkylation process incorporating the regeneration process is also described. | 05-27-2010 |
20110079540 | Novel process and catalyst system for improving dewaxing catalyst stability and lubricant oil yield. - The invention provides for a process for dewaxing a waxy hydrocarbon feedstock to form a lubricant oil. The invention is also directed to a catalyst system comprising a hydrotreating catalyst upstream of a dewaxing catalyst, used in the dewaxing of a waxy hydrocarbon feedstock to form a lubricant oil. In particular, the invention is directed to a process and catalyst system designed to maintain yield of lubricant oil product. Specifically, the yield of lubricant oil does not decrease more than 2%, at a target pour point, over a dewaxing temperature range. The hydrotreating catalyst helps prevent aging of the dewaxing catalyst and maintains lubricant oil product yield at a target pour point over a wide temperature range. The hydrotreating catalyst comprises platinum, palladium, or combinations thereof on a low acidity inorganic oxide support where acidity is measured by a decalin conversion of less than 10% at 700° F. | 04-07-2011 |
20120024752 | Multi-Stage Hydroprocessing for the Production of High Octane Naphtha - An integrated process is provided for producing high octane naphtha. Hydrocracked naphtha from a hydrocracking reaction zone is contacted with a reforming catalyst that includes a silicate having a silica to alumina molar ratio of at least 200, and a crystallite size of less than 10 microns. Products from the reforming include a reformed naphtha and a hydrogen-rich stream, which is passed to the hydrocracking reaction zone. | 02-02-2012 |
20120024753 | MULTI-STAGE REFORMING PROCESS TO PRODUCE HIGH OCTANE GASOLINE - The present invention relates to a multistage reforming process to produce a high octane product.
