Co-pyrolysis Characteristic and Parameters Optimization of Low Rank Coal and Eichhornia Crassipes

摘要

Orthogonal experiments were carried out in a fixed reactor to investigate the optimum operation conditions of co-pyrolysis of Hongying coal (HC) and eichhornia crassipes (EC) with the index of tar. The results showed when biomass ratio was 35%, final temperature was at 550 °C, particle size was 0.355-0.500mm and stay time was 25min, the content of alkanes and H/C ratio of co-pyrolysis tar were significant increased compared that of tar from coal pyrolysis alone.
