and a step c) in which at least a portion of the product from step b) is sent to a distillation zone from which a gaseous fraction, a gasoline type engine fuel fraction, a diesel type engine fuel fraction and a liquid fraction which is heavier than the diesel type fraction are recovered...
Further, the catalytically active material, more particularly the zeolitic material, is present in an amount which will generally be higher according as the feeds to be cracked are heavier and will generally be in the range of 5 to 50, more particularly 10 to 30 percent by weight, based on...
The invention is especially valuable in the stabilization of gasoline derived from the cracking of petroleum. :0 Many of the present day gasolines contain unsaturated compounds which are capable of oxidation on exposure to air to form various products, some of which are of a gummy or resinous...
