Abstract: A process for selectively recovering a phenolic compound from feedstock comprising bio-crude and/or bio-oil is described. The recovery efficiency of the selected phenolic compound is greater than 70 wt % and the purity of the recovered selected phenolic compound is higher than 80 wt %. The process comprises distilling the feedstock to isolate the selected phenolic compound in a first distillate fraction comprising the selected phenolic compound, concentrating the selected phenolic compound from the first distillate fraction in a concentrated mixture, and purifying the concentrated mixture to recover the selected phenolic compound.

Abstract: A catalyst is described that is useful for catalytic pyrolysis of biomass to produce a pyrolysis product. The catalyst includes (i) matrix material comprising a support and/or binder, and (ii) at least one metal oxide on the matrix material, wherein the metal oxide comprises metal selected from the group consisting of tungsten, chromium, cobalt, molybdenum, nickel, and combinations thereof. Corresponding catalytic pyrolysis processes and catalytic pyrolysis apparatus are disclosed, in which the catalyst enables the production of low oxygen content, stable liquid intermediates that can be refined to make liquid hydrocarbon fuels.

Abstract: Described herein are processes for converting a biomass starting material (such as lignocellulosic materials) into a low oxygen containing, stable liquid intermediate that can be refined to make liquid hydrocarbon fuels. More specifically, the process can be a catalytic biomass pyrolysis process wherein an oxygen removing catalyst is employed in the reactor while the biomass is subjected to pyrolysis conditions. The stream exiting the pyrolysis reactor comprises bio-oil having a low oxygen content, and such stream may be subjected to further steps, such as separation and/or condensation to isolate the bio-oil.
Abstract translation: 本文描述了将生物质起始材料（例如木质纤维素材料）转化成可被精制以制备液体烃燃料的低含氧稳定液体中间体的方法。 更具体地，该方法可以是催化生物质热解方法，其中在反应器中使用除氧催化剂，同时对生物质进行热解条件。 离开热解反应器的物流包含具有低氧含量的生物油，并且这种物流可以经受进一步的步骤，例如分离和/或冷凝以分离生物油。
