摘　　要：通过大量文献调研,综述了实现加压条件下高升温速率的煤焦制备方法的工作原理和设备特点,包括加压丝网反应器、加压平面火焰炉及加压沉降炉等,分析了这些方法的优缺点,得出加压沉降炉是一种较为理想的装置.介绍了清华大学开发的国内第一台加压沉降炉制焦系统,其工作压力范围是0.1 MPa^3.1 MPa,温度最高为1 873K,颗粒输送速率范围可达0.6g/h^6g/h,有较长的恒温区间,可以完成加压和高颗粒升温速率的煤焦制备.According to investigation of other researchers＇ work,the article summarizes the principles and the features of coal char preparation methods at high heating rate under pressurized condition,including PWMR,HPFFB,PDTF etc.By comparing the methods,PDTF is the ideal system.At last,the first domestic PDTF system developed by Tsinghua University is introduced,which achieves a pressure range of 0.1 MPa-3.1 MPa,a temperature range up to 1 873 K,a particle feed rate of 0.6 g/h-6 g/h,and a comparatively long constant temperate length.Different coal char can be produced at high pressure and high heating rate conditions by the PDTF system.
