    摘要: An apparatus and method for removing mercury, and in particular elemental mercury, from a fluid stream by exposing the fluid stream to a polyethersulfone or filter-coated with anion exchange resin, or anion exchange resin-coated surface onto which has been loaded elemental iodine. Elemental iodine is loaded onto the PES or anion exchange resin-coated surface by immersing the PES or anion exchange resin-coated substrate in an iodine/pentane solution, then removing the substrate from the iodine/pentane solution and rinsing in pentane.

    摘要: An energy efficient series of mass and energy integrated reactive distillation columns and distillation columns are used to effect the production of diaryl carbonate. Utilizing the method or apparatus of the invention facilitates high diaryl carbonate production rates, and convenient recovery of unreacted starting materials and side-reaction products for recycle within the process for making diaryl carbonates or utilization in parallel reactions such as the manufacture of dialkyl carbonates. The method makes use of three reactive distillation columns and two rectification columns which are joined by a plurality of lines for transferring reactants and/or products into and out of the columns.

    摘要: Process for treatment of gases which are exhausted through a sinter bed in a sintering plant, wherein a distinction can be made between a cold zone of the sintering plant with relatively low gas temperatures and a hot zone of the sintering plant with substantially higher gas temperatures. The gases from the cold zone of the sintering plant and the gases from the hot zone of the sintering plant are exhausted and treated as separate partial flows.

    摘要: A process and apparatus for contacting reactants with a particulate catalyst while indirectly contacting the reactants with a heat exchange medium performs heat exchange in a first reaction zone and moves catalyst, at least intermittently, through the second reaction zone while the process is operating. The first reaction zone is preferably a fixed bed reaction zone. The use of first reaction zone as a fixed bed reaction zone simplifies the process arrangement by not requiring means for catalyst movement in a reaction zone that performs simultaneous heat exchange. Long periods of operation are possible since the first reaction zone will typically experience a slow rate of catalyst deactivation and need infrequent regeneration. The first reaction zone may also be designed for catalyst movement, but independently controlled from the first reaction zone to facilitate the movement of catalyst therethrough.

    摘要: A transalkylation reactor having a plurality of catalyst beds with individual feed points for each bed for converting poly alkylated benzene, typically products from a alkylation process, to mono alkylated benzene. Only so many of the catalyst beds are used to optimize the conversion of poly substituted benzene to mono substituted benzene. As the catalyst ages more of the beds are utilized to maintain conversion.
