PROCESS FOR THE HYDROGENATION OF HYDROCARBON RESINS USING CATALYSTS WITH PROTECTIVE COATINGS
The present invention relates to a process for the hydrogenation of an unsaturated hydrocarbon feedstock comprising: (1) preparing a granular material, wherein the particles of the granular material comprise a hydrogenation catalyst, or a precursor thereof, and one or more organic compounds, wherein the one or more organic compounds comprise one or more carboxlic acid and/or one or more ester and/or one or more ether moieties; (2) providing an unsaturated hydrocarbon feedstock; (3) preparing a mixture comprising the granular material obtained in (1), the unsaturated hydrocarbon feedstock provided in (2), hydrogen gas, and optionally a solvent system; (4) heating the mixture prepared in (3) to a temperature in the range of from 210 to 360° C. for hydrogenating the hydrocarbon feedstock.
METHOD OF MANUFACTURING RENEWABLE DIESEL FROM BIOLOGICAL FEEDSTOCK
A method for producing renewable diesel includes introducing a primary feedstock comprising biologically-derived triglycerides with catalyst poisons into a first reaction chamber and hydrolyzing the primary feedstock within the first reaction and liquid-liquid extraction chamber for at least an hour such that the reacted triglycerides are separated into an aqueous solution comprising glycerol and catalyst poisons, and an intermediate feedstock comprising free fatty acids and catalyst poisons. The method also includes distilling the intermediate feedstock to separate the intermediate feedstock into a purified intermediate stream and a lower volume bottom stream containing unreacted triglyceride, diglyceride, monoglyceride, FFA and catalyst poisons. The method also includes combining the purified intermediate feedstock with a hydrogen stream and converting, in a second reaction chamber comprising a metallic catalyst bed, the purified intermediate feedstock into a product comprising long-chain alkanes. The method also includes hydrotreating the purified intermediate feedstock into a renewable diesel product.
CATALYST CONSISTING OF GRAPHENE-SUPPORTED NANOPARTICLES FOR SELECTIVE OIL HYDROGENATION AIMED AT THE PRODUCTION OF CIS-OLEIC ACID AND THE REDUCTION OF TRANS-OLEIC ACID
A nano-catalyst which is usable in processes of vegetable oil hydrogenation for producing bio-lubricants or biodegradable plastics for producing copolymers, characterized in that it consists of an active phase composed of nickel, palladium and ruthenium, dispersed on a support including graphene layers less than 1 micron, the outer surface of which is covered with surfactant chains, and having a high activity and a very high selectivity for the cis-configuration of the 9-octadecenoic acid (cis-oleic acid).
IMPROVED PROCESS FOR THE SELECTIVE HYDROGENATION OF VEGETABLE OILS
Process for the catalytic hydrogenation of vegetable oils wherein the oil is placed in contact with molecular hydrogen in the presence of a metal catalyst, and the process is performed in the absence of water or in the presence of a quantity of water equal to or less than 5:1 with respect to the weight of the metal catalyst and at a temperature equal to or less than 50° C.

Purification of recycled and renewable organic material
A method is disclosed of purifying a recycled or renewable organic material, wherein the recycled or renewable organic material includes more than 1 ppm silicon as silicon compounds and/or more than 10 ppm phosphorous as phosphorous compounds. The method can include providing a feed of the lipid material; heat treating the organic material in presence of an adsorbent and the filtering organic material and hydrotreating the lipid material in a presence of a hydrotreating catalyst to obtain purified hydrotreated organic material having less than 20% organic material and/or less than 30% of the original phosphorous content of the organic material.
Method of obtaining paraffinic hydrocarbons from natural fat
A method of obtaining paraffinic hydrocarbons from fat, by an exemplary method, whereby the method is performed in two stages, in a coupled flow-type system, under atmospheric pressure conditions, in the presence of heterogeneous catalysts, after their thermal activation, so that in Stage I the fat and/or waste fat is heated at a temperature range of 100-500° C., in the presence of an inert gas, in the presence of a catalyst in the form of a metal oxide on an oxide support or in the form of a mixture of at least two metal oxides on an oxide support. The product obtained in Stage I is treated, in the presence of an inert gas, at a temperature range of 100-500° C., in the presence of a metallic catalyst on an oxide support, with hydrogen gas or with a mixture of hydrogen and carbon monoxide, obtained in the selective decomposition of methanol.
PREPARATION METHOD FOR POLYUNSATURATED FATTY ACID-CALCIUM
