Claim:
A process for producing low oxygen biomass-derived pyrolysis oil comprising contacting a carbonaceous biomass feedstock with a microporous crystalline zeolitic catalyst at pyrolysis conditions to produce pyrolysis gases comprising hydrocarbons, the catalyst catalyzing a deoxygenation reaction converting at least a portion of the oxygenated hydrocarbons into hydrocarbons and removing the oxygen as carbon oxides and water; and condensing a condensable portion of the pyrolysis gases to produce low oxygen biomass-derived pyrolysis oil; wherein the catalyst comprises: a. a microporous crystalline zeolite, UZM-44, having a three-dimensional framework of at least AlO 2 and SiO 2 tetrahedral units and an empirical composition in the as synthesized and anhydrous basis expressed by an empirical formula of: Na n M m k+ T t Al 1-x E x Si y O z where “n” is the mole ratio of Na to (Al+E) and has a value from approximately 0.05 to 0.5, M represents a metal or metals selected from the group consisting of zinc, Group 1 (IUPAC 1), Group 2 (IUPAC 2), Group 3 (IUPAC 3), the lanthanide series of the periodic table, and any combination thereof, “m” is the mole ratio of M to (Al+E) and has a value from 0 to 0.5, “k” is the average charge of the metal or metals M, T is the organic structure directing agent or agents derived from reactants R and Q where R is an A,Ω-dihalogen substituted alkane having 5 carbon atoms and Q is at least one neutral monoamine having 6 or fewer carbon atoms, “t” is the mole ratio of N from the organic structure directing agent or agents to (Al+E) and has a value of from 0.5 to 1.5, E is an element selected from the group consisting of gallium, iron, boron and combinations thereof, “x” is the mole fraction of E and has a value from 0 to about 1.0, “y” is the mole ratio of Si to (Al+E) and varies from greater than 9 to about 25 and “z” is the mole ratio of O to (Al+E) and has a value determined by the equation: z =( n+k·m+ 3+4 ·y )/2 b. and wherein the microporous crystalline zeolite, UZM-44, is further characterized in that it has the x-ray diffraction pattern having at least the d-spacings and intensities set forth in Table A: TABLE A 2-Theta d(†) I/Io % 7.72 11.45 m 8.88 9.95 m 9.33 9.47 m 12.47 7.09 w-m 12.85 6.88 vw 14.62 6.05 vw-w 15.27 5.80 w 15.57 5.68 w 16.60 5.34 w 17.70 5.01 vw-w 18.71 4.74 w-m 19.30 4.59 w 22.55 3.94 m 23.03 3.86 vs 23.39 3.80 s 24.17 3.68 m 25.01 3.56 m 26.19 3.40 vw-w 26.68 3.34 w-m 28.76 3.10 w-m 30.07 2.97 w 35.72 2.51 vw-w 45.08 2.01 w 45.83 1.98 vw-w 46.77 1.94 vw-w.
