Abstract (EN): Gasification converts biomass into synthesis gas that can be further processed into high value products, e.g., methanol and hydrogen. Prior to the synthesis process, the bio-synthesis gas must be conditioned, which includes the removal of CO 2 for subsequent sequestration and capture. The most common technologies used for CO 2 removal from synthesis gas (syngas) are absorbent-based systems. A pressure swing adsorption (PSA) process for the replacement of the absorbent-based CO 2 removal process is put forward. A PSA cycle was developed for the simultaneous production of a CO 2 enriched stream and a (H 2+CO) stream with the required specifications of the Fischer-Tropsch reactor feed. An activated carbon was selected as adsorbent. It was possible to obtain a CO 2 product with purity above 95% and with 90% recovery. Moreover, a H 2/CO stoichiometric ratio of 2.14:1 was obtained for the produced syngas stream, which is adequate for further processing in the Fischer-Tropsch reactor. The power consumption of the CO 2 capture was 3.36 Mw - a reduction of ¿ 28 % when compared to a Rectisol process with the same CO 2 recovery. This is an abstract of a paper presented at the 2011 AIChE Spring Meeting & 7th Global Congress on Process Safety (Chicago, IL 3/13-17/2011).
