1P-340 Optimizing conditions for catalytic fast pyrolysis of biomass using Pt/TiO<sub>2</sub>
오신영,( Calvin Mukarakate ),최준원 한국공업화학회 2017 한국공업화학회 연구논문 초록집 Vol.2017 No.1
Catalytic fast pyrolysis (CFP) of loblolly pine with atmospheric hydrogen pressure was investigated in a lab-scale laminar entrained flow reactor (LEFR) vapor phase upgrading system. The effects of vapor phase upgrading temperature and hydrogen partial pressure has been studied using the Pt/TiO<sub>2</sub>. Experiments have been carried out under following conditions: 380-450°C; 50-85% H<sub>2</sub>; biomass to catalyst ratio of 3:1. The 85% of hydrogen at 400°C favored organic oil quality (HHV: 40.97 MJ/kg; H/Ceff: 1.05). The catalyst was reused after regeneration and reduction. The organic oil and aqueous phase were characterized and compared with the pyrolysis oil to determine the effect of catalytic fast pyrolysis. The organic oil contained methyl phenols with some ketones, and aromatic hydrocarbons. Compared with the compounds in liquid products, the catalyst reused 21 times with regeneration and reduction process, and catalyst activity was differed with different reduction conditions.
