摘要： PURPOSE:To carry out the titled modification in good thermal efficiency, by providing a subsidiary reaction part in a main reaction part, using a hot gas fed to the main part as a main heat source, and a high-temperature processing gas after the reaction as a subsidiary heat source. CONSTITUTION:A processing raw material gas is passed from the inlet 3 to the catalyst pipe 8 of the main reaction part A, and introduced from the thin pipe 1 to the subsidiary reaction part B. In the operation, a hot gas from the high- temperature gas furnace is fed from the inlet for the hot gas to the main reaction part, the reaction in the catalyst pipe 8 is promoted by heating, and the hot gas is discharged from the outlet 7 for the hot gas. While, another processing gas is separately fed from the inlet 4 to the main reaction part, passed through the catalyst pipe 9, subjected to the reaction, and joined to the processing gas passed through the catalyst pipe 8 at the subsidiary reaction part B. In the operation, the amount of heat required for the reaction in the catalyst pipe 9 is supplied by the high-temperature processing gas after the reaction form the catalyst pipe 8. The processing gas after the reaction is discharged from the outlet 5.

摘要： PURPOSE:To improve the thermal efficiency, etc. of a device with executes the steam reforming reaction of hydrocarbon in a reaction pipe made into double-pipe construction by inserting a baffle member which generates distur bance in the flow of the gas flowing along the inside surface of the pipe into the inside pipe. CONSTITUTION:The reaction pipe A which consists of the inside pipe 1 and the outside pipe 2 and in which the inside pipe 1 and the outside pipe 2 are connected at one end is prepd. A steam reforming catalyst layer 4 is packed into an annular space part formed between the inside pipe 1 and the outside pipe 2 and further the baffle member B which generates the disturbance in the flow of the gas flowing along the inside surface of the pipe is inserted into the inside pipe 1. Such reaction pipe A is disposed in a heating furnace and a gaseous mixture 5 composed of hydrocarbon and steam is introduced into the catalyst layer 4 to generate the steam reforming reaction. The reformed gas 6 obtd. in such a manner is discharged in an arrow direction; at the same time, the reformed gas 6 of a high temp. and the gaseous mixture 5 and efficient ly subjected to a heat exchange so that the quantity of heat of the high temp. gas 6 is effectively recovered.

摘要： PURPOSE:The separate high-purity CO from a CO-containing gas in high yield continuously and effectively, by using plural reaction zones, carrying out elimination treatment at a pressure lower than that of absorption treatment, carrying out elimination and absorption treatment only at one zone. CONSTITUTION:In separating and recovering CO from a mixed gas, when two processes of absorption and elimination are carried out by using the same amount of an absorbent, it is assumed that (a) minutes are required for absorption, and (b) minutes for elimination. When (a

摘要： PURPOSE:To adjust automatically the temp. of reformed gas at the outlet of a steam reformer by adjusting the amount of fuel fed to the reformer in accordance with output obtd. by synthesizing outputs for controlling feedforward and feedback based on the temps. of the inlet and outlet. CONSTITUTION:Light HC as a starting material is fed to a catalyst tube 15b in a steam reformer 14 through a convection section 15a while adjusting the amount with a flow rate controller 3. Steam is sent to a mixing section 11, mixed with said HC fed 5, heated to a prescribed temp. in a duct in the section 15a, and sent to the tube 15b. A temp. signal showing the temp. of the inlet of the reformer 14 detected 34 is fed 35 to a feedforward controller 26 as an inlet signal, and a signal showing the set value of a feedback controller 25 is fed through a signal line 35 as an input signal. The controller 26 estimates a change in the working conditions of the reformer 14, and it feeds 31 a signal to a modifier 32 so as to adjust the working conditions of the reformer 14 to that desired.

摘要： PURPOSE:To effectively reform a hydrocarbon with steam through effective reuse of high-temp. heat of a reformed gas without use of any waste heat boiler, by effecting the steam reforming in a tubular space portion of a particular reaction tube and effecting CO conversion in an inner tube portion. CONSTITUTION:A steam reforming catalyst layer A is formed in a space portion 4 between an inner tube 1 and an outer tube 2 which cooperate with each other to form a double-tube structure and communicate with each other through a partitioning plate 3 which has a number of fine pores for transmission and which is provided at the opening portion located at the bottom of the inner tube 1, while a CO conversion catalyst layer B is formed in an inner space 5 of the inner tube 1, thereby forming a reaction tube 20. For example, three reaction tubes are provided within a heating oven of a steam reforming device. A raw material comprising a mixed gas comprised of a hydrocarbon and steam and having a temp. of 300-400 deg.C is fed through a conduit 21. The mixed gas comes down from the direction of an arrow 10 of each reaction tube through the catalyst layer A. At this time, the mixed gas is heat- exchanged with the heat of gas rising through the catalyst layer B and heat from the outer surface 2, thereby causing the mixed gas to be heated at about 800 deg.C. This is turn causes the mixed gas to be converted into a gas contg. H2, CO and CO2. The gas rises through the catalyst layer B to bring about a CO conversion reaction. The gas thus formed is led to the direction of an arrow 11 and discharged from a discharging port 23 through a gas collecting tube 22, to transfer it to the next step.
