    摘要: In a method for reforming low grade coal to a carbonaceous material suitable for the production of metallurgical coke, steam coal (noncoking coal), such as sub-bituminous coal, brown coal, etc., is mixed with a catalyst, a co-catalyst (sulfur) and a hydrocarbonaceous heavy oil, and the mixture is thermally reformed in a reducing gaseous atmosphere at elevated pressure and temperature (400.degree. to 450.degree. C.) and the resultant reaction mixture is distilled at a reduced pressure of 40-150 mm Hg and at a temperature of 280.degree. to 350.degree. C. An iron type catalyst is used in proportions up to 3 wt.% based on the coal (on an ash-free, dry basis). The sulfur and heavy oil are recycled.

    摘要: A truss type extruded aluminum section (1) is formed of a pair of planar plates (2)(3) and ribs (4)(5)(6), wherein hollow portions (7)(8)(9) are formed within the section (1) by the ribs (4)(5)(6) and the planar plates (2)(3). Vibration-damping resin is provided on the inner surfaces of hollow portions (7)(8)(9), and particularly on the inner surface of the planar plate (3) and on a single surface of the inclined rib (4). With this arrangement, the vibration energy bending the planar plate (3) and the rib (4) is converted into a heat energy. In the case of manufacturing such truss type extruded aluminum vibration-damping section (1), for making easy the insertion of the vibration-damping resin in the hollow portion, the vibration-damping resin is stuck on a plastic film (11) to form a long planar body. The plastic film (11) serves as a cover or an adhesive. Moreover, in the case of directly inserting the vibration-damping resin sheet (14), the vibration-damping resin sheet (14) is subjected to embossing on the adhesive-bonding side for allowing air to escape. Additionally, in the case using an age-hardening type aluminum alloy, the adhesive-bonding for the vibration-damping resin by heating is performed along with the heat treatment for age-hardening.

    摘要: The invention provides a novel process for concurrently carrying out production of reduced iron and thermal cracking of heavy oils in which the reaction of thermal cracking is performed in a fluidized state with the fine iron ore as the fluidized medium and the particles of the iron ore become coated with deposits of the carbonaceous by-product material. The fine iron ore with the carbon deposited thereon is introduced in a fluidized-bed reducing furnace and there reduced into reduced iron by contacting with a reducing gas which is produced in a gas reformer from the cracked gas or the residual oil separated from the products of the thermal cracking. In an improvement of the above process, the gas reformer is operated as a fluidized-bed reactor with the reduced iron as the fluidized medium and acting as the reforming catalyst. The reduced iron partially re-oxidized in the reforming reaction is again reduced to completely reduced iron either by recycling into the fluidized-bed reducing furnace or by introducing into a second fluidized-bed reducing furnace.
