外文摘要：In this paper, thermogravimetric (TG) analysis is used to study the effects of alkaline earth and alkali metals compounds on catalytic thermal decomposition of microalgae. When alkaline earth and alkali metals were added, the initial thermal degradation temperatures increased by about 3.1-12.9K, and the end temperatures reduced by about 0.5-13.7K. The results show thatCaO MgO, K2CO3, BaCO3 and Na2CO3 may shorten the pyrolysis time, which means that alkaline earth and alkali metals may promote the thermal degradation of organic matters. The most catalytic peak temperauture of microalgae is lower than for the case without catalyst when catalyst mass percent is 1% and 2%, the peak temperauture of 3 mass% Na2CO3 and BaCO3 is higher than without catalyst, it's value is 341.9°C and 342.3°C respectively.
