摘要： PROBLEM TO BE SOLVED: To provide a method for producing an auxiliary binder for stock coal to be charged into a coke oven, friendly to environments because of its low content of low-boiling hydrocarbons and easily mixed with the stock coal because of its low viscosity. SOLUTION: This method produces an auxiliary binder for stock coal to be charged into a coke oven, little susceptible to thermal polymerization, by equilibrium flash distillation, where coal tar as a by-product of coke production is charged into a flash distillation tower 4 provided with upper and lower chambers for 2-stage equilibrium flash distillation, and the coal tar stream charged into the distillation tower top and the other stream charged into the bottom of the upper chamber are heated, the sensible heat of the coal tar streams being used as the latent heat of vaporization by which lower-boiling compounds are distilled off to be separated. At the same time, steam is injected into the bottom of the distillation tower 4, while keeping a vacuum in the tower, to distill off and separate lower-boiling compounds from the coal tar streams at lower temperature.

摘要： PURPOSE:To obtain the title reactor, the temp. of which can be easily controlled, by providing a metallic ball-packed bed on the upstream side of a catalyst bed, and furnishing nozzles for charging a fluid not contributing to the reaction in the spaces between the respective catalyst beds and the succeeding metallic ball-packed bed. CONSTITUTION:The multistage fixed bed catalytic reactor main body 1 is firstly heated by a heater 8 approximately to the operation temp. when a process fluid is charged. A liq. and a gas each preheated to the operation temp. are then fed from a feed port 9. Consequently, the liq. travels along the surface of the metallic ball in the metallic ball-packed bed 4, disperses in the radial direction, and descends. The gas passes through the gap between the metallic balls, and both components flow respectively into the catalyst-packed bed 3. An exothermic reaction occurs among the three gaseous, liq., and solid phases in the catalyst-packed bed 3, and the temp. is increased. The temp. is measured by a thermocouple 7 inserted into the catalyst-packed bed 3. When the measured temp. increases rapidly, the fluid not contributing to the reaction is fed from the nozzle 6 inserted in the space 5 to absorb the heat of reaction.
