Methanol dehydration on alumina xerogel catalyst

In this research a reaction of dehydration of methanol to dimethyl ether on a microporous amorphous alumina xerogel catalyst was studied. The catalyst possess a high surface area (475 m2/g).

Preparation and Characterization of Aerogel and Xerogel Alumina Catalyste and Comparted it in Catalyst of Alunina Used as Support for some Metal Oxides

The Xerogel alumina catalyst was prepared by sol-gel method in non-aqueous milieu, and the aerogel alumina catalyst was prepared in the same method but it was dried at by supercritical conditions. These catalysts were characterized by XRD, BET, and chemical adsorption methods. The obtained results were compared to show the effect of preparation process on the structural properties of the alumina. Besides these results were compared with some oxides supported on alumina, and the effect of distribution of these oxides on the properties of alumina was investigated too.

Thermal and Catalytic Cracking of Rubber Polystyrene

This research depends on treating different waste polystyrenes like; general purpose polystyrene, foamed polystyrene (styropor), high impact, and rubber modified polystyrene (HIPS) by thermal cracking in order to have liquid products which might be used as additives to gasoline. These products are essentially aromatics and aromatic olefines of a high octane number > ١٠٠, free from sulfer and lead, and they are able to be used as octane boosters. It is possible to redistill these products in order to have styene monomer with a yield of ٤٠ - ٤٣٪, which can be used after that for polymerisation purposes.
