Abstract:
1. A method for producing propylene containing biomass-derived carbon comprising: converting ethanol obtained from biomass to ethylene by a dehydration reaction; separating the ethylene, generated water, unreacted ethanol and a by-product; purifying the separated ethylene by adsorption, in which an adsorbent containing a deoxygenating agent comprising copper oxide and aluminum oxide is used to obtain an ethylene containing a ketone, an aldehyde and an ester which have been mixed in during the ethanol fermentation process, carbon dioxide which is a decomposition product thereof, an amine and an amino acid which is decomposition product or a contaminant of an enzyme, and ammonia which is a decomposition thereof in an amount of 10 ppm or less as total amount; and then performing a metathesis reaction with a raw material containing n-butene.
