Production and activity of sillimanite and sillmanite-zeolite aluminosilicate catalysts
This paper contains data on the use of sillimanite as an active filler in the manufacture of solid catalysts, and on the use of these catalysts for chemical decomposition of phenolic tars into valuable products and in cracking of petroleum fractions for production of increased yields of gasoline and unsaturated carbons. Data are presented on the technology of sillimanite production and on its use as an active component in aluminosilicate catalysts with addition also of zeolite at the point of synthesis of metal silicate sols and gels. The conditions of the syneresis, activation, drying, and heating stages of the production of sillimanite aluminosilicate catalysts were studied, and the optimal conditions for obtaining catalysts having improved activity and selectivity were determined. An account is given of the technology of obtaining very pure and active sillimanite, used as a filler for aluminosilicates, from sillimanite ore.
