With Control Of Water Content Of Recycled Catalyst Patents (Class 585/704)
  • Patent number: 9656421
    Abstract: A process is described for the preparation of an inorganic material with a hierarchical porosity in the micropore and mesopore domains. The material has at least two elementary spherical particles having a maximum diameter of 200 microns. The process comprises: a) preparing a solution containing zeolitic nanocrystals with a maximum nanometric dimension equal to 60 nm based on silicon and/or precursor elements of proto-zeolitic entities based on silicon; b) mixing, in solution, metallic particles or at least one metallic precursor of metallic particles, a surfactant and the solution obtained in accordance with a) such that the ratio of the volumes of inorganic and organic materials, Vinorganic/Vorganic, is 0.29 to 0.50; c) aerosol atomization of the solution obtained in b) resulting in formation of spherical particles; d) drying the particles; g) eliminating any remaining precursor elements of proto-zeolitic entities based on silicon and the surfactant.

  • Publication number: 20030073876
    Abstract: Improved methods for conducting solid acid-catalyzed, near- or supercritical heterogeneous chemical reactions (e.g., alkylation reactions) are provided which give enhanced product yields and permit longer processing runs. The preferred reactions of the invention are carried out in the presence of a solid macroporous catalyst having a surface area of from about 50-400 m2/g and a pore size of from about 70-150 Å. Product selectivity is enhanced by pressure-tuning of the reaction to promote production and separation of desired reaction products. In continuous processing, the chemical reaction may be interrupted before significant catalyst deactivation, followed by increasing reactor pressure and/or reducing reactor temperature to remove the accumulating coke; when the catalyst is regenerated, the original reaction conditions and reactant introduction may be resumed.

  • Patent number: 6492571
    Abstract: This invention relates to a process for alkylation of an isoparaffin with an olefin over a solid-acid catalyst, wherein at least two parallel reactors are used at the same time. When the solid acid catalyst in one or more reactors need to be regenerated, the catalyst is contacted in-situ in the reactor with a solvent to wash out the macromolecular hydrocarbons deposited on the surface of the catalyst in order to resume the high selectivity of catalyst in alkylation.

  • Patent number: 5648588
    Abstract: Disclosed is a process for separating sulfone and hydrogen fluoride from hydrocarbon streams containing a concentration of such compounds. An extraction solvent laden with sulfone and HF is contacted with a reversible base in order to remove the HF therefrom. The thus-treated extract stream is separated into a water stream that can be reused as the water extractant and a sulfone stream that is suitably free of HF.
