Molecular Sieve Patent

 

Molecular sieve compositions, catalyst thereof, their making and use in conversion processes

The invention relates to a catalyst composition, a method of making the same and its use in the conversion of a feedstock, preferably an oxygenated feedstock, into one or more olefin(s), preferably ethylene and/or propylene The catalyst composition comprises a molecular sieve and at least one oxide of a metal from Group 4 optionally in combination with at least one metal from Groups 2 and 3 of the Periodic Table of Elements.

Molecular sieve compositions, catalyst thereof, their making and use in conversion processes

The invention relates to a catalyst composition, a method of making the same and its use in the conversion of a feedstock, preferably an oxygenated feedstock, into one or more olefin(s), preferably ethylene and/or propylene The catalyst composition comprises a molecular sieve and at least one metal oxide, such as a magnesium oxide that, when saturated with acetone and contacted with said acetone for 1 hour at 25.degree. C., converts more than 80% of the acetone.

Process for production of molecular sieve adsorbent blends

A process for the production of a molecular sieve adsorbent blend product with improved performance characteristics produced by preparing a zeolite powder, preparing a highly dispersed attapulgite fiber binder, mixing the zeolite powder with the highly dispersed attapulgite binder to form a mixture, forming molecular sieve adsorbent products into a shaped material and calcining the shaped material, wherein the tapped bulk density of the highly dispersed attapulgite fibers measured according to DIN/ISO 787 is more than about 550 g/ml.

Method of making molecular sieve catalyst

Disclosed is a method for making molecular sieve catalyst particles. Dried molecular sieve catalyst particles are used to make the catalyst. The dried molecular sieve catalyst particles are put into an aqueous solution and stirred to make a slurry. The slurry is dried to make the molecular sieve catalyst particles. Optionally, the dried molecular sieve catalyst particles made from the slurry are calcined.
