PROCESS FOR RECOVERING CARBON MONOXIDE FROM CATALYTIC FAST PYROLYSIS PRODUCT |
摘要 |
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). |

1. An improved process for recovering CO from a catalytic fast pyrolysis process product effluent comprising steps of:
a) providing a first vapor phase stream resulting from a catalytic fast pyrolysis 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 solvent having an absorption capacity for CO2 that is at least 5 times, or at least 10 times, the absorption capacity of the solvent for CO 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). |
