N2 - Biomass can be converted to transportation fuel using number of thermochemical approaches, e.g., fast pyrolysis. Pyrolysis oil derived from fast pyrolysis of lignocellulosic biomass contains about 40-50% oxygen including the oxygen in water. Removal of oxygen from pyrolysis oil and molecular weight reduction are paramount for increasing its heating value, thermal stability, volatility, and miscibility with crude oil. The catalytic hydrodeoxygenation of 2-Methoxy-4-Propylphenol (4-Propylguaiacol (4PG)) in removing oxygen to produce aromatic compounds and other hydrocarbons was studied. This reaction is performed in a packed bed microreactor to take advantage of improved heat and mass transfer characteristics. The influence of different processing conditions, e.g., temperature, hydrogen partial pressure, reactor diameter, and residence time on conversion, yield, hydrogen consumption, and space-time-yield was explored using presulfided Ni-Mo/Al 2O 3 catalyst. External and internal mass transfer resistances as well as heat transfer resistance are evaluated, and an intrinsic kinetic data on the hydrodeoxygenation of 4PG was analyzed. This is an abstract of a paper presented at the 2012 AIChE Spring Meeting and 8th Global Congress on Process Safety (Houston, TX 4/1-5/2012).
