    摘要: The present invention comprises a thermo catalytic process to produce diesel oil from vegetal oils, in refineries which have two or more Catalytic Cracking (FCC) reactors. At least one reactor processes heavy gasoleum or residue in conventional operation conditions while at least one reactor processes vegetal oils in proper operation conditions to produce diesel oil. This process employs the same catalyst employed in the FCC process, which processes conventional feedstocks simultaneously. This process transforms high heat content raw materials into fuel hydrocarbons. It shows excellent efficiency for the obtention of highly pure products and do not yield glycerin, one by-product of the transesterification process. The diesel oil produced by said process presents quality superior and cetane number higher than 40. Once cracking reactions occur at lower temperatures, it forms less oxidized product, which is consequently purer than those obtained by existent technology are.

    摘要: A process for reducing the naphthenic acidity of petroleum oils or their fractions is described, said process comprising providing a hydrocarbon feed 103/203/303 having between 0.1 and 99 wt % of emulsified/dispersed water in oil, said feed containing salts and a content of naphthenic acids measured as TAN between 0.1 and 10 mg KOH/g oil; directing the said petroleum oil feed and emulsified/dispersed water towards an energy emitter device in the microwave range and submitting said feed 103/203/303 in liquid phase, under pressure between 0.7 and 4.5 MPa at temperatures between 50° C. and 350° C. to the microwave radiation, applied in the range of 1 mm to 30 cm to said feed so that the presence of salts, the applied temperature and the high dielectric constant of the water droplets make that the heat is absorbed on the spot by the water and heat said water preferentially to the oil, while the naphthenic compounds at the interface between the droplets and the oil catch said heat; effecting the decomposition of the carboxylic acids responsible for the naphthenic acidity in the petroleum feed at temperatures around 320° C. and generating CO2; separating with the aid of any known device 106/106′/112/117/208/208′/214/219/310/310′/316/321 any gas phase generated, water and oil; and recovering the hydrocarbon oil stream 108/113/119/210/215/221/312/317/323 having a reduced content in naphthenic acids. The process is designed to be applied to the reduction of naphthenic acids in feeds of petroleum oils and their fractions in the oil production step, in refineries or any industrial installation.
