    Abstract: A process is disclosed for an improved catalyst stripping process. The stripping vessel is divided into two zones. The first zone is a stripping zone where a substantial portion of the volatile hydrocarbons is removed at higher severity conditions. After the catalyst is stripped, the stripped catalyst moves to the lower cooling zone to be cooled at lower severity conditions. The flow rates, temperatures, pressures and the stripping and cooling zones are designed to ensure there is minimal volatile hydrocarbons on the catalyst by the time it leaves the stripping vessel. This design enables efficient stripping of volatile hydrocarbons at high severity conditions and eliminates these components from being stripped off elsewhere in the unit causing process and equipment issues.

    Abstract: A method for alkylation of a feedstock is described. The method includes contacting the feedstock comprising at least one alkylatable aromatic compound and an alkylating agent with a first alkylating catalyst composition under alkylating conditions, the first alkylating catalyst composition comprising UZM-8 zeolite and a binder, the first alkylating catalyst composition having 2-20 wt % UZM-8 zeolite and the catalyst having a nitrogen to zeolite aluminum molar ratio of between about 0.01 to about 0.040; wherein a total alkylated selectivity at a temperature and a molar ratio of alkylatable aromatic compound to alkylating agent is greater than 99.0%.

    Abstract: A process is disclosed for the aromatization of light aliphatic hydrocarbons, such as propane, into aromatic hydrocarbons. The process provides increased aromatics production, decreasing methane and ethane production, coke fouling and decreasing heavy aromatics. This improvement for the aromatization of light aliphatic hydrocarbons is achieved by introducing heavier of the light alphatic hydrocarbons in the feed to the lag reactors.
