Shanghai Jiao Tong University
Conclusion October 22-24,20182: October 22-24,2018GC-MS showed that 102 types of chemical compounds were detected and most of the compounds were condensed at different condensers. The selective condensation is useful to separate the water and chemical compounds from bio-oil compared with direct contacting condensing.
