    摘要: A method is disclosed for synthesizing a reactive sulfur-containing adsorbent material for removing metals, preferably mercury, from hydrocarbon fluids. The method includes impregnating a porous polystyrene resin with elemental sulfur, and heating the impregnated resin/sulfur mixture to chemically fix the sulfur to the resin. The elemental sulfur may be in solid, liquid, or vapor phase under conditions of contact with the resin. Also disclosed is the reactive adsorbent synthesized by this method. Also, a process is disclosed for removing mercury from hydrocarbon fluids by using a reactive adsorbent of the invention.

    摘要: A solid product resulting from the nucleated growth of the product on solid material of either the same or different composition and having a density higher than the reaction medium is formed from one or more liquid phase reactants by a method which comprises tangentially introducing the liquid phase reaction medium into the lower, smaller end of an inverted, frusto-conical reactor-separator, thereby imparting an upward swirling motion to the reaction medium in the reactor-separator, the horizontal velocity at the bottom of the reactor-separator being sufficiently large to cause fluidization of larger, solid product particles and concentration of them in the central lower portion of the reactor-separator and the vertical velocity at the top of the reactor-separator being sufficiently small to avoid carry-over of the smaller solid particles but sufficiently large to concentrate them in the upper portion of the reactor-separator; at least periodically recovering the larger, solid product particles in spherical form from the bottom of the reactor-separator; and recovering fluid products from the top of the reactor-separator. The method described is useful in a variety of reactions wherein a solid product forms by a nucleated growth mechanism. Examples of such reactions include thermal upgrading of petroleum derived feedstocks and coal liquids, synthesis of zeolites and Ziegler-Natta polymerization of olefins.

    摘要: A method for regenerating a spent porous crystalline catalyst, optionally associated with a metal component such as noble and/or base metal(s), is described. The method comprises contacting the spent catalyst which has become deactivated by accumulation of carbonaceous residue with one or more light aromatic compounds under conditions resulting in reactivation of said catalyst. The light aromatic compounds employed are ones which have the capability of penetrating the catalyst, so as to contact the carbonaceous residue contained therein, undergoing alkylation by alkyl fragments contributed by components of the carbonaceous residue and diffusing from or otherwise escaping the catalyst.
