| Abstract: | A lignite carbonization system with a stepping sieve working mode was introduced. The system is for the carbonization and upgrading of small lignite grains. The lignite travels across the dry section, carbonization section, waste heat recovery section and the cooling section, via the stepping sieve to facilitate its carbonization and upgrading, and pro-duce coal tar and semicoke product, thus the utilization efficiency of the lignite is effectively improved. |

| Keywords: | lignite stepping sieve low temperature carbonization upgrading |
