    摘要: A process is described for maximization of light olefins, preferably ethylene, by the catalytic cracking of feeds of saturated hydrocarbons, with molecular size in the range from 4 to 6 carbon atoms. The process uses a catalyst based on a zeolite of type ZSM-5 with low sodium content and modified with nickel, with concentration by weight of nickel, expressed in the form of oxide, in the range from 0.1% to 20% relative to the weight of zeolite in the catalyst, and operating conditions that involve a temperature between 400° C. and 650° C. and feed partial pressure between 0.1 and 1.0 MPa, so that the product recovered is rich in light olefins, with ethylene/propylene ratio in the range from 0.25 to 2.00.

    摘要: The present invention relates to a method of production of light olefins, with the objective of maximizing the production of propylene and in particular ethylene by the use of a special catalyst containing high-silica zeolite, whose composition also includes a dehydrogenating metal, so as to generate light olefins and appreciable deposition of coke on the catalyst. Gains in selectivity for light olefins are observed, and at the same time the energy deficiency of catalytic cracking in petrochemical operations with light hydrocarbons is minimized, avoiding problems due to the need to burn heating oil in the catalyst regenerating section to make up for the energy deficit of the converter.

    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.
