A method for making a zeolite includes providing a reaction mixture containing mixed inorganic oxides and an organic templating agent, heating the reaction mixture, removing the templating agent at a temperature of no greater than 550&#xb0; C. and under conditions such that the resulting zeolite is has an AAI of at least 1.2. The zeolite is preferably zeolite beta, TEA-mordenite or TEA-ZSM-12.

Zeolites and molecular sieves and the use thereof

An improved zeolite having a high number of strong acid sites wherein said zeolite has an AAI of at least 1.0. In a preferred embodiment, such zeolite is produced by controlling conditions after production of the crystalline structure such that loss of tetrahedral aluminum is minimized to thereby provide a zeolite with the above defined AAI.

A process of selectively hydrogenating an impurity in a feed containing hydrocarbons, such as, for example, an impurity selected from the group consisting of acetylene compounds, dienes, and mixtures thereof in a feed containing at least one monoolefin and the impurity wherein the impurity is hydrogenated selectively in the presence of a selective hydrogenation catalyst supported on a particulate support. The supported catalyst is supported on a mesh-like structure.
