| Number | Title | Issue Date |
| 7396967 | Manufacture of xylenes using reformate A process is provided for the production of xylenes from reformate. The process is carried out by methylating under conditions effective for the methylation, the benzene/toluene present in the reformate outside the reforming loop, to produce a resulting product havi... | 07/08/2008 |
| 7326818 | Selectivation of molecular sieve catalysts and use therof in hydrocarbon conversion In a process for preparing a selectivated catalyst composition useful in the disproportionation of toluene, a catalyst comprising an acidic molecular sieve is contacted with a boron compound at a temperature in excess of 500° C.; and the resultant catalyst is then ... | 02/05/2008 |
| 7288184 | Process for mitigating acids in a system for separating aromatic hydrocarbons from a hydrocarbon feedstream Disclosed is a process for removing acids in a system in which aromatic hydrocarbons are separated from a mixture with aliphatic hydrocarbons. The aromatic hydrocarbons are extracted from the mixture using an extracting solvent. The aromatic hydrocarbons are strippe... | 10/30/2007 |
