Abstract

or Ga-modified SiO2 or GeO2 having a porous crystalline structure and specific surface area >150m2/g has the general formula si(0.0012-0.0050)Al.Oy; Ge(0.0012-0.0050) Al.Oy; Si(0.0012-0.0050)Ga. Oy%Ge (0.0012-0.0050)Ga. Oy; where y = 2.0018-2.0075. A zeolite has the general formula (0.9 plus-or-minus 0.2)M2/n 0.W2O3. (5-100)YO2.zH2O, where M = cation H+ and/or NH4 + and/or metallic cations and/or cations derived from amino alcohols; n = valency of cations; W = Al or Ga; Y = Si or Ge; z = 0-40. The modified SiO2 or GeO2 is prepd. by (a) reacting a deriv. of Si or Ge and a derivative of Al or Ga with a substance having an archivolt or clathrating effect, in an aq., alcoholic or aq. alcoholic medium, (b) crystallising reaction mixt. at 100-220 degrees C (c) cooling, (d) sepg the ppte and (e) firing the ppte, in air at 300-700 degrees C. The modified SiO2 GeO2 or the zeolite is used as catalyst for alkylation of hydrocarbon, pref 4C to high octane hydrocarbon. Regenerable catalysts give high conversion rates for alkylation (100%) and for conversion of CO and propylene in automobile exhausts (99%). Acidity of the modified SiO2 and GeO2 can be tailored for a desired application. The materials are also useful adsorbents.
