Abstract
An oligomerization catalyst, oligomer products, methods for making and using same. The catalyst can include a supported nickel phosphate compound. The catalyst is stable at oligomerization temperatures of 500° C. or higher and particularly useful for making oligomer products containing C4 to C26 olefins having a boiling point in the range of 170° C. to 360° C.
Claims7
A method for making a nickel phosphate catalyst, comprising:
- providing a solution of a nickel hydrate and a Lewis base;
- adding a support material to the solution to provide a supported nickel catalyst;
- calcining the supported nickel catalyst;
- mixing a phosphate with the calcined supported nickel catalyst to form an impregnating solution containing nickel phosphate;
- and
- calcining the impregnating solution to obtain a supported nickel phosphate catalyst.
