Pyrolysis characteristics and bio-oil of Chlorella vulgaris were investigated under SiC and ZnO (SZ) mixture (compound additive) with various mixing ratios (S/Z = 10:0, 7:3, 5:5, 3:7, 0:10) and addition amounts (5%, 10%, 15%) by thermogravimetric analysis and GC–MS. At three experimental groups of 10% compound additive, as ZnO in compound additive increased, maximum weight loss rate (Rₚ) increased, the time (tₚ) corresponding to Rₚ and the weight stabilization time (tf) first decreased and then increased, while average rate of weight loss (Rₐ) and total weight loss (M) first increased and then decreased; maximum temperature rising rate (Hₓ) and average rate of temperature rising (Hg) increased, while the time (tₓ) corresponding to Hₓ decreased. Compound additives reduced the bio-oil yield, increased the gas yield, and reduced the acid compounds in bio-oil. Besides, it might promote the production of alicyclic hydrocarbons and oxygen/nitrogen-containing long-chain compounds.
