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.

摘要： 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.

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 process for the preparation and modification of additives, with a zeolite base and a high silica alumina ratio (SAR) like the ZSM-5, to increase the yield of propene and LPG in low severity FCC operations, that seeks to maximize the production of medium-distillates with low aromaticity and to minimize molecular cracking in the LCO range. The additives involved guarantee an increase in light olefin yields without altering the yield or the quality of the LCO produced. The innovative process includes surprising actions from rare earths (RE) on the active sites of zeolite, that at once partially block their pores and, in this way, make molecular cracking in the medium-distillate range difficult, which preferably occur at low reaction temperatures and keeps the remaining sites quite active. These sites are sufficiently active to crack smaller molecules in the gasoline range, guaranteeing an overall increase in light olefins and allowing the additive involved to be used industrially in operations to maximize medium-distillates in an FCC unit. This new additive may be obtained by modifying any commercial ZSM-5 zeolite additive.

摘要： The present invention concerns the field of fluid catalytic cracking (FCC) processes. The invention provides a process increasing production of LPG and propene in FCC units operating under conditions of maximisation of middle distillates of low aromaticity, such that they may be incorporated into the diesel oil pool. The invention also relates to the preparation and employment of additives based on zeolites having small pores, such as ferrierite (FER), in catalytic systems for FCC units, wherein conditions of low severity are adopted with a view to increasing yields of LPG and light olefins whilst improving stability of petrol. The invention also provides an original catalytic system, being more efficient than catalytic systems known in the state of the art, to increase the yield of LPG and propene without prejudicing the yield and quality of LCO. Furthermore it provides a method of preparation of an additive for said process employing the zeolite ferrierite.

摘要： A FCC process for the maximization of medium distillates from feedstocks of different sources, by the contact of the feedstock which circulates in a riser reactor together with a fine particulate catalyst from a regenerator (6), under FCC conditions of maximum LCO, at temperatures between about 480° C. and about 520° C., in the absence of added hydrogen, and with injection of coolant or quench to a riser ascendant R, and where the process consists of the injection of a coolant proportion between about 200 and about 50 kg/m3 of feedstock, preferably between about 100 and about 50 kg/m3 of feedstock, in a zone (3) of the riser ascendant R in a position located between about 25% and about 50% of the height of said riser R above the feedstock inlet mouths (2), the injection in this position resulting in the increase of the catalyst circulation and the temperature increase in the starting segment of the riser, yielding the production of medium distillates with low aromatic compounds content and bottoms conversion lower than when the coolant injection is employed in the base of the riser R as it is handled in the prior art processes.
