The present disclosure relates to solid phosphoric acid (SPA) catalysts useful in the conversion of hydrocarbons, such as the oligomerization of olefins, to methods for preparing such SPA catalysts, and to methods for converting hydrocarbons by contacting hydrocarbons with such catalysts method. For example, in certain embodiments, the present disclosure provides a calcined solid phosphoric acid catalyst composition comprising phosphoric acid and a silicophosphate, and wherein (i) a species each selected from the group consisting of boron, bismuth, tungsten, silver, and lanthanum is present one or more cocatalysts; (ii) the composition is the calcined product of a shapeable mixture comprising silica-alumina clay, silica fibers, and/or silica alumina fibers; or (iii) ) composition is the calcined product of a shapeable mixture comprising fumed silica. |
