Abstract
A catalyst system comprising a silicoaluminophosphate impregnated with a compound selected from the group consisting of phosphoric acid, boric acid, tributyltin acetate, and combinations of any two or more thereof, and a method of preparing such catalyst system, are disclosed. The thus-obtained catalyst system is employed as a catalyst in the conversion of a hydrocarbon feedstock comprising oxygenated hydrocarbons to olefins and/or ethers.
Claims27
A catalyst system comprising a silicoaluminophosphate impregnated with tributyltin acetate, to thereby form an impregnated silicoaluminophosphate.
A method of preparing a catalyst system comprising the step of impregnating a silicoaluminophosphate with tributyltin acetate, to thereby form an impregnated silicoaluminophosphate.
A process for converting at least a portion of a feedstock comprising methanol to at least one ether, said process comprising:
- impregnating a silicoaluminophosphate with a solution comprising phosphoric acid, said phosphoric acid present in said solution in the range of from about 10 weight % to about 40 weight %, based on the total weight of said solution, to thereby produce an impregnated silicoaluminophosphate;
- and
- contacting said feedstock with said impregnated silicoaluminophosphate at conversion conditions to thereby form a reaction product comprising at least one ether;
- and
- recovering said reaction product.
