Study on Brown Coal Pyrolysis and Catalytic Pyrolysis

It is very important to the combustion processes of coal pyrolysis, so the catalytic effects of alkali, alkaline earth and transition metal on the brown coal (Yunnan,China) were investigated with a thermogravimetric analysis. These results show that the active pyrolysis orders are Mg>Ni,Fe>Na,K>Al2O3>CaO, and the maximal increment of conversion is 10.6% in brown coal.
