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： A multifunctional additive for maximizing yield of light olefins and LPG, with a tolerance to contaminant metals. Maximization of the referenced properties is accomplished through the use of a zeolite treated with a phosphorus source, calcined and impregnated with a rare earth salt. The process for preparation of the referenced catalyst includes the following steps: preparation of a precursor containing a zeolite that is selective of olefins with a source of phosphorus; placement of a source of phosphorus in this precursor through calcination; deposition of rare earth salts on the surface of the additive for maximizing the yield of light olefins and LPG that forms; and drying the multifunctional additive formed.

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.
