Abstract: A crystalline, galliosilicate molecular sieve having the faujasite structure is synthesized by mixing a hydrogel having the following oxide mole ratios of components:SiO.sub.2 /Ga.sub.2 O.sub.3 =6 to 15Na.sub.2 O/Ga.sub.2 O.sub.3 =1 to 5H.sub.2 O/Ga.sub.2 O.sub.3 =80 to 500with a clear galliosilicate solution having the following oxide mole ratios of components:SiO.sub.2 /Ga.sub.2 O.sub.3 =5 to 30Na.sub.2 O/Ga.sub.2 O.sub.3 =6 to 20H.sub.2 O/Ga.sub.2 O.sub.3 =200 to 800to form a mixture. The resultant mixture is then crystallized without stirring at a temperature below about 150.degree. C. to form the galliosilicate molecular sieve with the faujasite structure.

Abstract: Delaminated clays whose X-ray diffraction patterns do not contain a distinct first order reflection are prepared from synthetic and natural swelling clays whose particles have a length-to-width rati greater than about 2.0, a length-to-thickness ratio greater than about 5.0 and are comprised of randomly oriented platelets by reacting the clay with a pillaring agent selected from the group consisting of polyoxymetal cations, mixtures of polyoxymetal cations, colloidal particles comprising alumina, silica, titania, chromia, tin oxide, antimony oxide or mixtures thereof, and cationic metal clusters comprising nickel, molybdenum, cobalt or tungsten and the subjecting the resulting reaction products to drying in a gaseous medium, preferably spray drying. The resulting acidic delaminated clays, which contain the microporosity associated with zeolites and pillared clays the the macroporosity associated with amorphous aluminosilicates, may be used as the active component of cracking and hydroprocessing catalysts.

Abstract: Hydrocarbon feedstocks containing relatively high levels of nitrogen contaminants are converted to products of lower average molecular weight by first mixing the feedstock with a dicarboxylic acid such as oxalic acid and then contacting the resultant mixture with a cracking catalyst in a cracking zone under cracking conditions in the substantial absence of added molecular hydrogen. The use of a dicarboxylic acid in lieu of a mineral acid such as sulfuric acid or nitric acid results in less corrosion to FCC unit internals and less emissions of sulfur and nitrogen oxides from the FCC unit regenerator.

Abstract: Hydrocarbon feedstocks containing relatively high levels of nitrogen contaminants are converted by catalytic cracking to products of lower average molecular weight by contacting the feedstock with a mixture of a cracking catalyst and separate particles of a nitrogen scavenger. The nitrogen scavenger is a particulate solid acid capable of sorbing pyridine at room temperature and retaining greater than about 5 weight percent of the sorbed pyridine after heating in a vacuum to about 300.degree. C. Examples of the nitrogen scavengers that can be used in the process include amorphous aluminosilicates, nonzeolitic molecular sieves such as pillared clays and delaminated clays, and zeolitic molecular sieves.
