    摘要: A process is described for fluid catalytic cracking of hydrocarbons with high levels of basic nitrogen, where hydrocarbon feedstocks A and B with different levels of basic nitrogen are injected in a segregated fashion, into different risers of a multiple riser FCCU that possesses at least two risers. The injection of the feedstocks is made in such a way that feedstock A, to be injected in the riser with greater volume—main riser 7—possessing a level of basic nitrogen at least 200 ppm lower than the level of feedstock B to be injected into the riser with lower volume—secondary riser (8).

    摘要: 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.

    摘要: A stripping apparatus for desorbing gases from solid particles through which flows counter-currently a stripping fluid is described, which comprises a series of sets of at least two parallel, segmented, baffle plates each, with the segmented baffles being oriented so that the rows are offset relative to rows of other levels, where the thickness and separation of said sets of baffles is so dimensioned as to reduce coalescence of the size of the formed bubbles and optimize the hydrocarbons desorption from said fluidized solid particles. The solid particles are mainly spent catalyst particles from a FCC process. The stripping process to be carried out in a fluidized bed comprises contacting the spent catalyst with a stripping fluid that flows upwardly in the fluidized bed in the form of bubbles. Adsorbed hydrocarbons present in the spent catalyst are transferred from the catalyst emulsion that flows downwardly to the upwardly moving bubbles, so as to promote the efficient recovery of cracked products.

    摘要: A process for the fluid catalytic cracking of mixed hydrocarbon feeds from different sources is described, such as feeds A and B of different crackability, the process being especially directed to obtaining light fractions such as LPG and comprising injecting feed A in the base of the riser reactive section and feed B, of lower crackability, at a height between 10% and 80% of the riser, with feed B comprising between 5% and 50% of the total processed feed. The process requires that the feeds present differences in the contaminant content, improved dispersion of feeds A and B and feed B injection temperature same or higher than that of feed A.
