The present invention refers to the processing of a 100% renewable load in FCC units, wherein the load comprises triglycerides of vegetable and animal source, free fatty acids, fatty acid esters, ketones, alcohols and long-chain aldehydes, using catalyst and appropriate operating conditions in order to obtain 100% renewable products with a high content of aromatic compounds, in the range of naphtha, kerosene, diesel and heavy gas oil. The product thus obtained complies with all the properties of the ASTM D1655 standard, even for contents of up to 10% renewable content. In addition, there is no need to reduce the freezing point of the fossil QAV for the introduction of the renewable component, with no impact on the yield and economy of the process.

The present invention relates to a process and equipment for fluid catalytic cracking for the production of middle distillates of low aromaticity that comprises cracking a mixed feed consisting of heavy fractions of hydrocarbons, in the absence of added hydrogen and employing a catalyst of low activity and low acidity, in a dense-bed FCC reactor to produce an effluent constituted of fractions of middle distillates and naphtha of low aromaticity.

A process is described for catalytic cracking of hydrocarbon feedstocks from petroleum refining which increases substantially the yields of light olefins. The process limits the extreme conditions to a first reaction section and introduces a stream of cooling fluid above the feedstock injection point so as to maintain a second reaction section under cracking conditions which produce light olefins propene and ethene, and inhibits reactions undesirable for the process.

Process for catalytic cracking of petroleum hydrocarbons in a fluidized bed with maximized production of light olefins

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 () are introduced in an intermediary region of the stripper () 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.
