Abstract: The present invention deals with a process for catalytic cracking of hydrocarbons comprising vacuum gas oil, hydrotreated vacuum gas oil, unconventional light crude oil, preferably unconventional light crude oil type shale/tight oil and its blends with conventional vacuum gas oil, in order to generate products of major commercial value in the field of fuels, getting improved gasoline and coke yield, as well as the procedure for the preparation of a catalyst with essential physical properties of density and particle size to uphold it in a fluidized bed under the operation conditions in the catalyst evaluation unit at micro level, wherein the catalyst particles achieve a catalytic performance similar to fluidized microspheres in a reactor, without appreciable generation of fine particles.

Abstract: The present invention relates to heterogeneous acid catalysts comprising or consisting of mixed metal salts, of lithium and aluminum phosphates and sulfates, and combinations with metallic cations, such as magnesium, titanium, zinc, zirconium and gallium, to provide adequate Lewis acidity; organic or inorganic porosity promoters, such as polysaccharides; and agglomerates, such as clays, kaolin and metal oxides of the type MxOy, where; M=Al, Mg, Sr, Zr or Ti, and other metals of groups IA, IIA and IVB, x=1 or 2 and y=2 or 3, for the formation of particles. A process is disclosed for obtaining from the catalyst by the hydrolysis of aluminum lithium hydride with water and oxygenated solvent, such as an ether. The catalysts are used in batch reactor and continuous flow systems in reactions that require moderate Lewis acidity, such as refining, petrochemical and general chemistry, including the transesterification of glycerides to produce alkyl esters.

Abstract: The present invention relates to the production of biodiesel and alkyl esters by the transesterification of triglyceride esters, with alcohols in heterogeneous phase in the presence of heterogeneous catalysts, with yields higher than 80%, at a temperature from 0 to 300° C., residence time from 20 minutes to 20 h, space velocity of 0.1 to 10 h−1, pressure of 25-100 kg/cm2 (24.5-98.07 bar), methanol/oil molar ratio of 10 to 40 and catalyst concentration of 0.001 to 20 weight % based on tri-, di- or monoglyceride. The method produces biodiesel and alkyl esters by transesterification of tri-, di- or mono-glycerides, from palm, jatropha, castor, soybean and sunflower oils, wherein the alcohoxyls R1O, R2O and R3O of the glycerides are C1 to C24 and a C1-C4 alcohol, such as methanol, in an alcohol:oil ratio from 3:1 to 50:1. The transesterification reaction produces biodiesel while avoiding loss of catalyst, contaminating liquid effluents and eliminating undesirable hydrolysis of triglycerides, diglycerides and monoglycerides into free fatty acids and saponification that generate soaps.
