TLDR
In this article, the alkylation of isoparaffin with olefin to provide alkylate is carried out in the presence of, as catalyst, a supported heteropoly acid.Abstract:
The alkylation of isoparaffin with olefin to provide alkylate is carried out in the presence of, as catalyst, a supported heteropoly acid. The support may be MCM-41, and the heteropoly acid may be dodecawolframophosphoric acid (i.e., phosphotungstic acid, i.e., H 3 PW 12 O 40 ).read more

Combination of amorphous materials for hydrocracking catalysts
TL;DR: An amorphous support as discussed by the authors is a type of material used for making the same and methods of using, particularly in hydrocracking, which can be modified by the different acidities of the precursor materials, their proportions in the mixture, and the order of the mixing and treating steps.

Solid super acids: Preparation and their catalytic activities for reaction of alkanes
TL;DR: In this article, the acid strength of SbF 5 -SiO 2 -Al 2 O 3 was analyzed and showed that both Bronsted and Lewis acid sites were present on the surface when SiO 2 −Al 2 -O 3 was treated at low temperatures below 100 °C, but only Lewis acids sites when treated at 300 °C.
