A reactor for the reforming of hydrocarbons by a steam reforming reaction and a partial oxidation reaction, which comprises an upper tube sheet disposed in an upper portion of the reactor, a plurality of reaction tubes packed with a catalyst and suspended perpendicularly from the upper tube sheet, a lower tube sheet disposed where lower portions of the reaction tubes are positioned, an internal cylinder suspended perpendicularly from the lower tube sheet, an oxygen distributor disposed in an upper portion of the internal cylinder and connected to a feed tube of an oxygen-containing gas which is fed from an exterior of the reactor, a catalyst-packed bed disposed in the lower portion of the internal cylinder, a flow path for feeding a mixture gas of hydrocarbon with steam disposed above the upper tube sheet, and a flow path for recovering reformed gas disposed below the upper tube sheet. Also provided is a process for the reforming of hydrocarbons by a steam reforming reaction and a partial oxidation reaction.

Reactor for reforming hydrocarbon

A hydrocarbon-reforming reactor by a steam reforming reaction and a partial oxidation reaction, which comprises a chamber for feeding oxygen-containing gas, a chamber for feeding a mixture gas of hydrocarbon with steam and a chamber for heat exchange of reformed gas in this order from one side of the reforming reactor, and which further comprises a catalyst layer filled in a space between an inner tube having an opening to the chamber for feeding oxygen-containing gas and a reaction tube being so placed as to position the inner tube in its middle portion and having an opening to the chamber for feeding the mixture gas, and a process for producing reformed gas from hydrocarbon which comprises carrying out a steam reforming reaction in the catalyst layer on the side of the chamber for feeding the mixture gas of hydrocarbon with steam by feeding the mixture gas of hydrocarbon with steam to the catalyst layer from the chamber for feeding the mixture gas, carrying out a partial oxidation reaction and steam reforming reaction by feeding oxygen-containing gas fed into the inner tube through the chamber for feeding oxygen-containing gas to the catalyst layer through holes or slits provided in that part of the inner tube which is located opposite to the chamber for feeding the mixture gas, and allowing the resultant, reformed gas to move out of the reforming reactor from the reaction tube through the chamber for heat exchange of reformed gas.

Process for the production of methanol

This invention provides a catalyst layer-fixed reactor for an exothermic reaction which comprises a plurality of reaction tubes disposed within a shell of the reactor, an inner tube disposed in the middle portion of each of the reaction tubes, catalyst layers formed by catalyst charged in the space inside the reaction tubes and outside the inner tubes, and a cooling medium charged between each of the reaction tubes and the shell, and in which a feed gas is flowed in each of the inner tubes in cocurrent to feed gas flowing in the fixed catalyst layer.

Catalyst layer-fixed reactor

A wetted wall type method of humidifying gas with a liquid which is composed, or mainly composed, of water wherein the liquid flows down a heated vertical wall to form a wetted wall and gas flows along the wetted wall in contact with the liquid on the wetted wall to increase the humidity contained in the gas, comprises supplying a greater amount of liquid than the amount of liquid used or evaporated for increasing the humidity, and recirculating the liquid which is not evaporated from an outlet of the wetted wall to a liquid supply portion, the amount of the flowing liquid being adapted to satisfy the following equation:
