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: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.

摘要： A liquid feed containing methanol, carbon monoxide, an alkyl iodide and a solvent is contacted with a supported rhodium catalyst to produce acetic acid at a temperature of 140-250 DEG C and a pressure of 15-60 kg/cm G with a partial pressure of carbon monoxide of 7-30 kg/cm while maintaining (a) the water concentration of the product solution in the range of 0.5-10 % by weight and (b) the carbonylation degree Cr, defined in the specification, of the solution within the reactor at 0.15 or more. The solvent may be a carboxylic acid or a carboxylic acid ester.

摘要： High purity, crystalline adduct of bisphenol A and phenol is produced multi-stage crystallization of a phenolic slurry of bisphenol A with a crystal separation being interposed between each stage. The purity of the phenol solvent which is used to prepare the solutions for the crystallization stages is controlled so as to increase progressively. The crystalline adduct obtained in the final crystallization stage is washed with purified phenol.
