    摘要: Catalysts solid particles are supplied to a vertical reactor for the catalytic treatment of fluid charges, at the upper part of said reactor and are progressively withdrawn from the lower part thereof either continuously or periodically through a funnel having the shape of an inverted cone or an inverted pyramid. At least a portion of the charge is introduced at the lower part of the reactor through orifices above the walls of the funnel at a distance thereof from 1 to 500 times the average size of a catalyst particle.

    摘要: Process for producing ethers by reacting a catalytic cracking C.sub.4 olefinic cut which may contain such impurities as NaOH, an alkanolamine, an alkaline earth metal compound or an iron, copper or lead compound, with an alcohol, in the liquid phase, in the presence of an expanded bed of an etherification solid catalyst of the sulfonic resin type in acid form, in a circuit of two or more successive reaction zones wherethrough the order of passage of the reactants is periodically modified by disconnecting the first zone from the circuit, feeding the reactants to the second zone, replacing the catalyst of the first zone with fresh catalyst and thereafter connecting said first zone at the end of the circuit.
