Amorphous hydrocarbon conversion catalysts and process for preparing same
Abstract
Abstract Novel amorphous compositions possessing catalytic properties may be prepared by controlled calcination of synthetic crystalline precursor material structurally related to the mineral alunite, said precursor material being prepared and crystallized from an aqueous reaction mixture having a composition expressed in terms of mole ratios of oxides as Q G2O : a Al2O3 : b M2O3 : c SO4 : d XO4 : e H2O wherein ''''G'''' represents NH4 , H , Ag or any mixture thereof, wherein M2O3 represents at least one oxide selected from the group consisting of Fe2O3, Cr2O3, V2O3, La2O3, and Ce2O3; XO4 represents at least one oxide selected from the group consisting of PO4, MoO4, VO4. SiO4 and TlO4; ''''q'''' has a value of from 0.5 to 6.0; ''''a'''' has a value of from 1.5 to 4.0: ''''b'''' has a value of from zero to 2.0; ''''c'''' has a value of from 8.0 to 10.0; ''''d'''' has a value of from zero to 2.0; ''''e'''' has a value of from 100 to 1,000; the sum of ''''a'''' + ''''b'''' has a value not exceeding 4.0.
