Improved process for recovering carbon monoxide from catalytic fast pyrolysis product

The present invention provides an improved process for recovering CO from a catalytic fast pyrolysis (CFP) process product effluent. The process comprises the steps of: a) providing a first vapor phase stream resulting from a CFP process comprising, on a water- free and solids-free basis, from 25 to 80 % CO and at least 15 % CO2, b) mixing the first vapor phase stream of step a) with a particular solvent to make a mixed phase stream, c) separating the mixed phase stream of step b) into a second vapor phase stream comprising CO and a liquid phase stream, and d) recovering a product stream from the second vapor phase stream of step c) having a higher concentration of CO and a lower concentration of CO2 than the first vapor phase stream of step a). 本发明提供了从催化快速热解(CFP)工艺产物流出物中回收CO的改进的方法。所述方法包括以下步骤：a)提供由CFP工艺产生的第气相流，所述第气相流在无水和无固体的基础上，包含25至80％的CO和至少15％的CO，b)将步骤a)的第气相流与特定的溶剂混合以得到混合相流，c)将步骤b)的混合相流分离成包含CO的第二气相流和液相流，以及d)从步骤c)的第二气相流中回收产物流，所述产物流具有比步骤a)的第气相流更高的CO的浓度和更低的CO的浓度。
