Abstract
The present invention relates to solid phosphoric acid (SPA) catalysts, processes for making the catalysts, and processes for conversion of hydrocarbons using the catalysts, such as oligomerization of propylene. In an exemplary embodiment, the catalyst comprises a calcined extrudate of phosphoric acid, diatomaceous earth, and niobic acid. Methods for converting hydrocarbons to olefins comprise contacting a hydrocarbon feedstock with the catalyst at hydrocarbon conversion conditions.
