Vacuum pinewood flash pyrolysis has been carried out in a bench scale plant provided with a conical spouted bed reactor. Product yields and properties have been measured at 1 and 0.25 atm and 400 ºC and 500 ºC. the conical spouted bed reactor is a suitable reactor for biomass vacuum flash pyrolysis, as high bio­oil yields have been obtained, 77 %wt at 500 ºC and 0.25 atm. Vacuum increases slightly bio­oil yields and reduces char...
