    Abstract: The invention relates to the integration of a process for hydrotreatment of distillates (light and/or middle), that operates under a hydrogen partial pressure of 0.5 to 6.0 MPa, with a process for hydrotreatment/hydroconversion of middle and/or heavy distillates that operates at a hydrogen partial pressure that is at least 4.0 MPa higher than the hydrogen partial pressure of the process for hydrotreatment of distillates (light and/or middle). The integration resides in the use of the hydrogen-rich gas, obtained from the hydrotreatment/hydroconversion effluents, in the process for hydrotreatment of distillates (light and/or middle) and in the adjustment of the pressure level of this hydrogen-rich gas removed from the hydrotreatment/hydroconversion. This invention makes it possible to considerably reduce the net consumption of make-up hydrogen in the process for hydrotreatment of distillates (light and/or middle).

    Abstract: An additive to enhance the activity of an FCC catalyst containing zeolite and matrix components comprises zeolite microspheres having a novel morphology comprising a macroporous matrix and crystallized zeolite freely coating the walls of the pores of the matrix. The additives formed from microspheres containing a metakaolin and kaolin calcined through its exotherm, the latter calcined kaolin being derived from a kaolin having a high pore volume. Kaolin having a high pore volume can be a pulverized ultrafine kaolin or a kaolin which has been pulverized to have an incipient slurry point less than 57% solids.

  • Publication number: 20040004023
    Abstract: An integrated fluid catalytic cracking (FCC) and desulfurization system for processing hydrocarbon-containing fluids. The integrated system employs a cracking/desulfurization unit having a reactor, a regenerator, and a reducer. A mixture of solid FCC catalyst particulates and solid sulfur sorbent particulates are circulated through the reactor, regenerator, and reducer to provide for substantially continuous cracking and desulfurization of the hydrocarbon-containing fluid, as well as substantially continuous regeneration of both the FCC catalyst and the sulfur sorbent.

  • Patent number: 6635169
    Abstract: The sulfur content of liquid cracking products, especially the cracked gasoline, of a catalytic cracking process is reduced by the use of a catalyst having a product sulfur reduction component containing a metal component in an oxidation state greater than zero, wherein the average oxidation state of the metal component is increased by an oxidation step following conventional catalyst regeneration. The catalyst is normally a molecular sieve such as a zeolite Y, REY, USY, REUSY, Beta or ZSM-5. The metal component is normally a metal of Groups 5, 7, 8, 9, 12 or 13 of the periodic table, preferably vanadium or zinc. The sulfur reduction component may be a separate particle additive or part of an integrated cracking/sulfur reduction catalyst. A system for increasing the oxidation state of the metal component of a Gasoline Sulfur Reduction additive is also provided.
