摘　　要：用低变质程度,高挥发分煤,于高压釜内在煤挥发分本身的压力下焦化。焦炭的机械强度与该煤种所受压力的1/3次方成正比。配合煤以其最大反射率等于1为好,焦化时压力的作用使配合煤生成光学各向异性的焦。炭化条件为升温10℃/min,500～600℃维持2h,然后5℃/min升温到950℃维持1h,能生成高强度的焦炭。The carbonization is carried out in autoclave under the pressure of volatile matter itself for low rank coals with high volatile matter content. The mechanical strength of the coke is in direct proportion to the third root of the pressure. It is better that maximum reflectance of coal blends equals one. The influence of pressure is on the development of optial anisotropy during carbonization of coal. Carbonization conditions: 10℃/min to 500～600℃, then to hold for 2h, carbonization 5℃/min to 950℃, then for 1h, to form coke of high strength.
