Abstract: An integrated process for the manufacture of olefins and intermediates for the production of ammonia and urea, comprising an FCC reactor, a regenerator, a steam reforming unit, an air-separation unit, an ammonia production unit and a urea production unit, is described. This process makes it possible to minimize CO2 emissions to atmosphere, make use of heavy feedstocks of low added value (AR) for the production of light olefins, in addition to making maximum use of all the flows involved, thus increasing the energy efficiency achieved, all at the same time.

Abstract: This invention concerns a fluid catalytic cracking (FCC) process with reduced carbon monoxide emission which modifies the regeneration phase of the spent catalyst by using pure oxygen without the need for dilution when burning coke adhering to the catalyst. In addition, this invention improves the reconditioning stage of the catalyst, incorporating a reconditioner supplementary to a conventional reconditioner which employs nitrogen as a carrier gas in the reconditioning of the already regenerated catalyst.

Abstract: Process for upgrading a liquid hydrocarbon feed comprising the steps of (a) preparing a slurry comprising the hydrocarbon feed having a boiling range above 350° C. and solid particles comprising a rehydratable material, (b) thermally treating said slurry at a temperature in the range of 250 to 550° C., (c) optionally separating the thermally treated slurry into (I) a lower boiling fraction and (ii) a higher boiling fraction containing the solid particles and formed coke, if any, and (d) separating the solid particles and formed coke, if any, from the thermally treated slurry resulting from step b) or the higher boiling fraction of step c).

Abstract: A process and device to optimize the yield of fluid catalytic cracking products through a reactive stripping process are disclosed. One or more hydrocarbon streams (3) are introduced in an intermediary region of the stripper (1) of a fluid catalytic cracking unit (FCC), from a device that allows a homogeneous distribution with adequate dispersion. This/these stream(s) react(s) with the catalyst of FCC, although its activity is reduced due to the adsorption of hydrocarbons in the reaction zone, generating products that improve and/or change the global distribution of products, providing a refinery profile adequate to meet quality demands and requirements.

Abstract: A process for reducing the naphthenic acidity of petroleum oils, or their liquid fractions, is described, the process comprising a thermal treatment of the petroleum oils, or their liquid fractions, in the presence of an adsorbent the surface of which is covered by high molecular weight carbon compounds. Preferred adsorbents are the spent or coked FCC catalysts.

Abstract: “FCC equilibrium catalysts, even when highly contaminated with vanadium, can be upgraded to make them suitable again for use in catalytic processes, for instance, as catalyst additives in FCC, by employing a process comprising the steps of (a) treating an FCC equilibrium catalyst that contains alumina and zeolite with an acidic solution to obtain an acid-treated equilibrium catalyst, and (b) contacting the acid-treated equilibrium catalyst with an aqueous solution or suspension of a divalent metal compound.
