| 20080286172 | Isomerization of Benzene-Containing Feedstocks - The benzene content in a gasoline pool is reduced by a process that hydrogenates a benzene-containing isomerization zone feedstream. The additional cyclic hydrocarbons produced by the saturation of benzene can be processed in the isomerization zone for ring opening to increase the available paraffinic feedstock or the isomerization zone can be operated to pass the cyclic hydrocarbons through to a product recovery section. The isomerization zone feedstream is treated to remove contaminants and dried before entering the hydrogenation zone. | 11-20-2008 |

| 20100314291 | Apparatus and Process for Isomerizing a Hydrogen Stream - One exemplary embodiment can be an apparatus for isomerizing a hydrocarbon stream rich in a C4 hydrocarbon and/or at least one of a C5 and C6 hydrocarbon. The apparatus can include: a first drier and a second drier adapted to receive a fluid including at least one reactant; and a reaction zone communicating with the first drier to receive the fluid including at least one reactant and with the second drier to receive the regenerant. Generally, the first drier operates at a first condition to dry the fluid including at least one reactant and the second drier operates at a second condition during regeneration with a regenerant. The regenerant is displaced from the drier using a down-flow regenerant displacement assembly. | 12-16-2010 |
