摘要： PURPOSE:To rapidly detect the abnormal feeding of coal by charging the coal into a hopper, increasing the pressure of a gas in the hopper with a pressing gas, introducing a pressure-controlling gas and a coal-fluidizing gas into the hopper, feeding the coal into a gasification oven with a coal-feeding gas and detecting the concentrations of the gases in the gasification product. CONSTITUTION:Coal is charged into a rock hopper 3, and a pressing gas is introduced into the rock hopper 3 through a press valve 23 to increase the pressure. A pressure-controlling gas 7 and a coal-fluidizing gas 8 are introduced into a feeding hopper 4 to control the pressure of the gas in the feeding hopper 4 and simultaneously fluidize the charged coal. The coal carried from the feeding hopper 4 is fed into a coal-gasification oven 12 with a coal-feeding gas 10. The concentrations of components in the pressure-controlling gas 7 and the coal-fluidizing gas 8 in the coal-feeding gas 10 passed through the coal- gasification oven 12 are detected, and the lowering of the feeding amount of the coal is detected on the basis of the increase in the detected concentrations of the components, thus rapidly detecting the abnormal feeding of the coal.

摘要： PURPOSE:To decrease generation of NOx so as to simplify the separating operation of CO2 after burning of generated gas by using oxygeon as an oxygeon source of a gas turbine as well as using exhaust gas as gas for coal supply, and gas for char circulation. CONSTITUTION:The air compressed by an air compressor 11 is supplied to a cryogenic separator 17, and oxygeon separated by the cryogenic separator 17 is supplied to a gas turbine 8 and a gasification furnace 4 through an oxygeon compressor 10. The exhaust gas mainly composed of CO2 cooled by a heat recovery device 12 is respectively supplied to a feed lines to the gas turbine 8 and the gasification furnace 4 for material coal 1 and to a circulation line for char collected by a dust collector 5 through an exhaust gas compressor 16. As it is, so constituted that no nitrogenous component except the nitrogen within the material coal 1 may be mixed in the system, NOx is hardly generated therein. Exhaust gas 24 in the outlet finally becomes CO2 independent gas, and not only it can be used as inactive gas, but also it can be easily collected in slip stream.

摘要： PURPOSE:To be able to operate a boiler with pulverized coal only using coal gas fuel as auxiliary fuel by installing a coal gasification device which is placed near the pulverized coal-fired boiler and gasifies a part supplied coal with gasifying agent such as air or oxygen. CONSTITUTION:Coal 9 supplied to a mill 7 from a coal supply line is crushed into pulverized coal. The pulverized coal is transferred into a pulverized coal burner 13 by a part of preheated air which is generated in an air preheater 3 for a pulverized coal-fired boiler 6 and used as transportation air via a heated- air piping 8. A part of this pulverized coal is introduced into a coal gasification device 20 through a pulverized coal pipe 19 for coal gasification and is gasified by gasifying agent from a piping 21 to produce auxiliary fuel which is supplied to the burner 13 from a pipe 22 for gasified auxiliary fuel. Thereby, the boiler is able to be started with only pulverized coal to save auxiliary fuel except pulverized coal.

摘要： PURPOSE:To obtain the titled substance economically with reduced steam consumption and investment cost, by synthesizing the titled substance by the oxidation of 1-butene and 2-butene in the presence of an oxygen catalyst, and separating the catalyst with a flash distillation column at a specific temperature and pressure. CONSTITUTION:Methyl ethyl ketone is synthesized by oxidizing 1-butene and 2-butene (line 1) in the oxidation reactor 6 in the presence of a catalyst activating oxygen by forming an oxygen complex. The reaction liquid of the oxidation reactor 6 is heated with the heat-exchanger 11 and the steam heater 12, and introduced to the catalyst-separation column 7 (a flash distillation column). The reaction liquid is separated into gas and liquid by the vacuum effect in the distillation column controlled to 60-100 deg.C and 0--0.7kg/cm G pressure. The aqueous solution of catalyst returned from the catalyst-separation column 7 is aerated in the oxygen-absorption column 5 with air 2 to form an oxygen complex. The objective substance is delivered from the line 13.

摘要： PURPOSE: The titled compound is produced by carring out the isobutene-removal pretreatment, and oxidizing the resultant raw material composed of 1-butene and 2-butene in the presence of a metal complex compound catalyst, converting unreacted 2-butene to 1-butene, and recyling to the raw material gas.
CONSTITUTION: A 4C fraction containing 1-butene and 2-butene is supplied through the line 5 to the reactor 6 containing the solution of O
2 -absorbed metallic catalyst (e.g. a catalyst solution prepared by adding a proper amount of water to PdCl
2 , CuCl, hexamethyl-phosphoramide and benzonitrile, and absorbing O
2 in the catalyst liquid in the O
2 -absorption column 8 to obtain an oxygen complex). Methyl ethyl ketone can be produced from 1-butene by this process. The residual 4C fraction containing 2-butene is introduced into the isomerization reactor 22, and the converted 1-butene is recycled to the reactor 6 as the recycling 4C fraction.
EFFECT: The objective product can be produced at a relatively low temperature and pressure in high yield.
USE: Solvent, detergent, polymerization initiator for the resin curing agent, etc.
