the reaction were fixed to meet a typical value as shown in Table 3. The components of biooil and gas as well as their compositions are referred in the literatures [11,20]. Biooil is the mixture of low and high molecular weight oxygenated-hydrocarbons such as phenols (e.g., phenol and cresol), furfurals, acids (e.g., acetic acid, formic acid, and lactic acid) and aldehydes (e.g., acetic aldehyde, and formic aldehyde) [29]. In this study, the 9 representative components were used for biooil, as is listed in Table 3.
