Abstract
The interaction between organic compounds from microalgae and low-rank coal during the co-pyrolysis process was explored via thermogravimetric analyzer combined with an online mass spectrometer. The influence of Glycine (GLE) on thermal behavior and kinetic characteristics from gaseous products generation of mixtures of acid washed low-rank coal (ALC) were investigated. Positive and negative synergistic effects from the pyrolysis parameters and products distribution were observed due to the interaction between GLE and ALC. The addition of GLE promoted the char formation under 75â¯wt% mixing ratio, with about 24â¯wt% deviation between the calculated value and experimental value. Negative synergistic effects from yield of CO2 and CH4 were found. Kinetic results showed that the order for activation energy was E(H2)â¯>â¯E(CH4)â¯>â¯E(CO)â¯>â¯E(CO2), which was consistent with the releasing sequence.
