摘要： PURPOSE:To obtain the subject complex useful as various reaction catalysts under mild conditions in a high yield by heating industrially easily available ruthenium oxide hydrate in a carbon monoxide atmosphere. CONSTITUTION:RuO2.nH2O and an inert solvent such as hexane or toluene are charged into an autoclave, carbon monoxide is blown optionally in combination with a compd. capable of coordinating with Rn and they are brought into a reaction at 120-200 deg.C under ordinary pressure - 200kg/cm to obtain the title complex. Since the starting materials do not contain halogen, ligand, etc., this method produces the advantage that a reaction system is not contaminated by by-products derived from halogen, ligand, etc., at the time of preparation of a catalyst.

摘要： PROBLEM TO BE SOLVED: To provide a simulation method capable of predicting the deformation of an oven wall in case of loading on the oven wall of a coke oven, a method for effectively operating the coke oven based on the simulation method, a method for efficiently repairing the coke oven, and a method for planning the coke oven. SOLUTION: The simulation method is to simulate deformation of an oven wall when a load is acted on the oven wall of a carbonization chamber of a coke oven of horizontal type by a calculation using a discrete element method. The method for operating the coke oven is to regulate the operational condition of the coke oven by regulating the deformation value of the oven wall calculated from the simulation to an allowable range. Further, the method for repairing the coke oven is to preferentially repair the oven wall by judging that a repairing is necessary when the deformation value of the oven wall deviates from the allowable range. Further, the method for planning the coke oven is to plan a stronger oven wall structure by selecting a less deforming structure by simulating deformations against loads for various oven wall structures.

摘要： PROBLEM TO BE SOLVED: To provide a method for simulating a load or pressure on a carbonzation chamber wall of a coke oven, which can directly predict a load or pressure on the wall of a commercial oven, and a local load or pressure on the wall, and also to provide a method for efficiently operating a coke oven, based on the results by the simulation method. SOLUTION: This method simulates, based on a discrete element method, a load or pressure on the whole wall of at least one side of a carbonization chamber of a horizontal coke oven, when coke produced in the oven is pushed out by a pusher, and also a local load or pressure on the wall. The method for operating a coke oven controls the operating conditions in such a way to keep the load or pressure, simulated by the above method, at or below the acceptable load or pressure, determined by the conditions of the carbonization chamber wall.

摘要： PROBLEM TO BE SOLVED: To maintain the strength of coke and simultaneously enlarge the granular diameter of the coke by charging raw material coal into the carbonization chamber of a coke oven so that the bulk densities of the charged raw material coal are low and high on the oven wall sides and on the oven core side, respectively, in the oven width direction. SOLUTION: In this method for producing coke for metallurgy by charging raw material coal into the carbonization chamber of a coke oven, the raw material coal is charged into the carbonization chamber so that the bulk densities of the charged raw material coal are low and high on the oven wall sides and on the oven core side, respectively, in the oven width direction, preferably in an oven wall side bulk density/oven core side bulk density ratio of about 0.70-0.95, especially about 0.80-0.85. The bulk densities are preferably controlled by a method comprising changing the granular diameters and granule size distribution of the raw material coal, although the bulk densities can be controlled, for example, by changing the kind of the coal, the mixing ratio of the coals or a method for charging the coal into the oven or by wetting the coal.

摘要： PROBLEM TO BE SOLVED: To measure the softening meltability of coal when coal is rapidly heated. SOLUTION: A cylindrical crucible 1 is filled with a ground coal sample and a stirring rod 2 is rotated with definite torque by a stirring device to measure the rotational speed of the stirring rod. The crucible is housed in a cylindrical dielectric sleeve 20 and heated by an induction heating coil 31 while inert gas is allowed to flow into the sleeve 20. A heating speed is controlled by a temp. regulator 33 and the temp. of the sample is measured by a thermometer 36. Softening meltability is calculated from the measured rotational speed and the measured sample temp. by a data processor 40. By this method, the softening meltability at a time of rapid heating at a sample temp. rising speed of 10 deg.-10000 deg.C/min is measured.
