Patent number: 4938930Abstract: A reaction vessel has a catalytic core, with an inlet for a first gas and for a second gas. The first and second gasses react in an exothermic reaction during passage through the catalytic core. The first gas passes through conduits which extend through the catalytic core, so as to be preheated and also so as to cool the catalytic core so that the catalyzed reaction proceeds in a preferred temperature range. The gasses are mixed at one end of the vessel in a mixing chamber, and are drawn through the catalytic core into a gathering chamber, from which the reacted gasses exit. A cooling chamber is provided for introduction of a cooling fluid about the periphery of the catalytic core, for drawing away any excess heat during operation.Type: GrantFiled: September 10, 1987Date of Patent: July 3, 1990Assignees: Mitsubishi Jukogyo Kabushiki Kaisha, Mitsubishi Gas Chemical Company, Inc.Inventors: Toshikazu Shinkawa, Daisaku Shozen, Kazuto Kobayashi, Hiroshi Makihara, Kensuke Niwa, Kazuhiro Morita, Masaaki Kuwa, Murayama Katsutoshi

Patent number: 4767791Abstract: A process for synthesizing material uses an exothermic reactor which comprises a coolant shell, two concentric pipes provided within the shell, a catalyst bed packed between inner and outer ones of the concentric pipes, an introduction tube connected to the inner pipe through which a starting fluid is introduced, and a communication path enabling the fluid after the passage of the inner pipe to be passed through the catalyst bed in a direction opposite to the direction of the passage through the inner pipe, the coolant shell having an inlet and an outlet for a coolant arranged in such a way that the flow of the coolant is parallel to the flow of the fluid within the catalyst bed. The coolant on the outside and the starting fluid on the inside of the catalyst bed cools the bed in such a way as to produce a temperature distribution along the bed that follows a maximum reaction rate line (M in FIG. 1) relating the concentration of the methanol to the temperature of the starting fluid.Type: GrantFiled: November 6, 1986Date of Patent: August 30, 1988Assignee: Mitsubishi Jukogyo Kabushiki KaishaInventors: Yoshimitsu Nakajima, Kensuke Niwa, Kazuhiro Morita, Hiroshi Makihara
