Claims. 01. 196-49 One oi. the main drawbacks of the several present methods of catalytically cracking mineral oil or fractions thereof is that after once carrying out such stepand fractionating the product" to recover the portion within the gasoline range,
thelarge remainder cannot be recycled with profit The motor fuel recovery from repeating the cracking is too smallto be commercially practicable and such remainder must be-tumed of fuel oil or some cheap product. 4 g r I have discovered that such remainder from catalytic cracking can be partially oxidized, pref- Jerablyby my well known vapor-phase catalytic process; and that if the oxidized product be then line or motor fuel range. I can thus largely increase the percentage of the desired product within the gasoline or motor spiritrange, and in some cases nearly double therecovery. In carrying out my process; the crude oil or a j fraction may be cracked in, the presence 01- a ccatalyst by any of the now well known processes, such as the Houdry, the aluminum chloride; or others, andthe product fractionatedto recover the portionwithin the gasoline range. The. re
p. mainder or such portion as it "is desired to reg I, .cycle for cracking is then treate'dto partially Jcxidize itg producing a series of oxygen derivatives in the range fromyalcohols to 'oxy-acids.

catalytic vapor-phase partial-oxidation method "wherein such portion is vaporized, mixedwith ,air or an oxygen containing gas and passed through a hot reaction zone preferably infcon tactwtih a catalyst such as'molybdenum,"'vanadium, .or uranium oxides or compounds.
