Catalytic Pyrolysis by Heat Transfer of Tube ...

Catalytic pyrolysis by heat transfer model can be solved the control temperature in tube furnace to produce bio-oil by continuous pyrolysis process and this study concern the products yield of bio-oil from mixed biomass consist of Cogongrass, Manilagrass and the leaf of trees, which conducted temperatures in the range of ~ 400-550°C, considering the feed rate of 150, 350, and 550 rpm (r?min?1)]. Preliminary result of proximate analysis was founded that the high volatile matter, low ash and moisture. The products yield calculation showed that the liquid yield of bio-oil was highest of 55.60 %, and 45.45%., at 350 rpm and 550 rpm., respectively, the solid yield of bio-oil was highest of 27.35 %, at 350 rpm, and the gas yield of bio-oil was highest of 43.60 %, at 150 rpm. Indicated that biomass from mixed biomass had good received yields because of low solid yield and gas yield and high liquid yield. The compounds detected in bio-oil from mixed biomass showed that the functional groups, especially; phenols. For the purpose that; In this research not only concern the feed rate and the heat transfer for contact biomass but also concern the control gas flow and temperature balanced.
