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.

A method for making light hydrocarbon oligomers, comprising:
- reacting one or more C2 to C12 olefins with a supported nickel phosphate catalyst at a temperature of about 500° C. or higher to provide an oligomer product comprising C4 to C26 olefins, wherein the nickel is present in an amount ranging from about 2 wt % to about 20 wt %, based on the total weight of the catalyst, and wherein the support material is silica having a pore size of about 50 Å to about 500 Å, and a surface area of about 100 m2/g to about 600 m2/g.
A method for making light hydrocarbon oligomers, comprising:
- reacting one or more C2 to C12 olefins with a supported nickel phosphate catalyst at a temperature of about 500° C. or higher to provide an oligomer product comprising C4 to C26 olefins, wherein the support material is amorphous silica and the nickel is present in an amount ranging from about 2 wt % to about 20 wt %, based on the total weight of the catalyst.
A method for making light hydrocarbon oligomers, comprising:
- reacting one or more C2 to C12 olefins with a supported nickel phosphate catalyst at a temperature of about 525° C. or higher to provide an oligomer product comprising C4 to C26 olefins, wherein the support material is amorphous silica having a pore size of about 50 Å to about 500 Å and wherein the nickel is present in an amount ranging from about 2 wt % to about 20 wt %, based on the total weight of the catalyst.
