Cracking of crude oils with carbon-hydrogen fragmentation compounds over non-zeolitic catalysts

Claim 1

The process for conversion of a crude oil feed comprising: (a) combining the crude oil feed with between about 1 weight percent and about 25 weight percent, based on total feed weight, of a carbon-hydrogen fragmentation compound selected from the group consisting of alcohols, acetals, aldehydes, ketones, aliphatic ethers, olefins, napthenes, paraffins containing from about 13.0 to about 25 percent by weight hydrogen and mixtures thereof; and (b) contacting the combined product of step (a) at effective catalytic cracking conditions with a catalyst comprising at least one non-zeolitic moleoular sieve selected from the group consisting of: (1) microporous crystalline silicoaluminophosphate having a unit empirical formula in the as-synthesized and anhydrous form of: mR:(Si.sub.x Al.sub.y P.sub.z)O.sub.2 wherein "R" represents at least one organic templating agent present in the intracrystalline pore system; "m" has a value of from zero to 0.3: "m" represents the moles of "R" present per mole of (Si x Al y P z )O 2 ; "x", "y" and "z" represent the mole fractions of silicon, aluminum and phosphorus respectively, present as tetrahedral units, said mole fractions being such that they are within the pentaqonal compositional area defined by points A,B,C,D and E of the ternary diagram which is FIG. 1 of the drawings; and (2) aluminophosphates having a framework structure whose chemical composition expressed in terms of mole ratios of oxides is: Al.sub.2 O.sub.3 :1.0±0.2 P.sub.2 O.sub.5 each of said framework structures being microporous in which the pores are uniform and have nominal diameters within the range of about 3 to about 10 Angstroms, an intracrystalline adsorption capacity for water at 4.6 torr and 24° C. of at least 3.5 weight percent, the adsorption and desorption of water being completely reversible while retaining the same essential framework topology in both the hydrated and dehydrated state.
