20090020457 | COATED CATALYST FOR AROMATIC ALKYLATION - A catalyst useful for multi-phase reactors that includes an active component surrounded by a coating on a surface of the active component, wherein the coating provides a liquid film around the active component to increase the useful life of the active component as compared to an uncoated active component. | 01-22-2009 |
20090023969 | COATED CATALYST FOR AROMATIC ALKYLATION - A catalyst useful for multi-phase reactors that includes an active component surrounded by a coating on a surface of the active component, wherein the coating provides a liquid film around the active component to increase the useful life of the active component as compared to an uncoated active component. | 01-22-2009 |
20090069607 | METHOD FOR THE PRODUCTION OF DIMETHYL ETHER - A process for the production of dialkyl ether, the process including: feeding a stream comprising an alkyl alcohol to a distillation column reactor system; concurrently in the distillation column reactor system: i) contacting the alkyl alcohol with a catalytic distillation structure in a distillation reaction zone thereby catalytically reacting at least a portion of the alkyl alcohol to form a corresponding dialkyl ether and water; and ii) fractionating the resulting dialkyl ether from the water; operating the distillation column reactor system to obtain substantially complete conversion of the alkyl alcohol to form the corresponding dialkyl ether and water; recovering the dialkyl ether from the distillation column reactor as an overheads fraction; recovering the water from the distillation column reactor as a bottoms fraction. | 03-12-2009 |
20090069608 | METHOD OF PRODUCING TERTIARY AMYL ETHYL ETHER - A process for the production of tertiary ethers, including: feeding a hydrocarbon stream comprising isoolefins and propionitrile to a distillation column reactor system containing at least one etherification reaction zone; feeding a C | 03-12-2009 |
20090182183 | PROPYLENE OLIGOMERIZATION PROCESS - A process for the oligomerization of propylene is disclosed wherein a tungstated zirconia catalyst prepared as a distillation structure is used in a reaction distillation zone under conditions of temperature and pressure to concurrently react the propylene to produce oligomers thereof and separate the oligomer products from unreacted propylene by fractional distillation in a distillation column reactor. Compared to the prior art tubular or plug flow reactors, lower temperatures and pressures are used to produce higher conversions and selectivities to preferred isomeric forms useful for preparing neo acids. | 07-16-2009 |
20100044273 | REFORMATE BENZENE REDUCTION VIA TRANSALKYLATION - A process for reducing benzene content in a reformate stream, including: fractionating a full range reformate comprising benzene, C | 02-25-2010 |
20100048966 | ALKYLATION SLURRY REACTOR - A process for alkylation of benzene, including: feeding benzene, a polyalkylate, and a catalyst to a reactor comprising a first and a second reaction zone; reacting the benzene and the polyalkylate in the first reaction zone under transalkylation conditions to form a monoalkylate product; feeding a C | 02-25-2010 |
20100048970 | REFORMATE BENZENE REDUCTION VIA ALKYLATION - A process for reformate benzene reduction, the process including: feeding a light reformate fraction, an olefin feed, and an alkylation catalyst to an alkylation reaction zone; contacting the light reformate fraction and the olefin feed in the presence of the alkylation catalyst in the alkylation reaction zone to convert at least a portion of the benzene and the olefin to a monoalkylate; recovering a catalyst fraction from an alkylation reaction zone effluent; and recovering a light reformate product having a reduced benzene content. | 02-25-2010 |
