摘要： In this paper, catalytic partial oxidation is applied as a thermo-chemical method to remove tar frombiogas and convert it into fuel gas by using a combined catalyst and oxygen carrier system. In this method, theamount of oxygen needed for the partial oxidation of tar will be supplied by an oxygen carrier, which will also serveas a carrier of the catalyst. Based on the results of laboratory tests, the perovskite material CSFM(Ca_(0.5)Sr_(0.5)Fe_(0.5)Mn_(0.5)O_(3-δ)) and ilmenite exhibited promising properties as oxygen carriers. They can supply a sufficientamount of oxygen for the oxidation of tar and show excellent redox properties for the regeneration. As a potentialcatalyst material, NiO showed high catalytic activity. During testing, the combined system of these two materialsshowed high ability for the removal of naphthalene, which was used as a model component for tar. In order to preventthe catalyst (NiO) from being poisoned by H_2S, H_2S sorbent were used. In combination with the combined catalystand oxygen carrier system, the use of H2S sorbent further enhanced the performance of the catalyst. In conclusion, thesuitable oxygen carrier materials, catalyst and sour gas sorbent could be identified, which in combination enable theproposed tar removal process.
