摘要	To raise H-2/CO and remove tar for biomass product gas, sodium titanates 4Na(2)O center dot 5TiO(2) and Na2O center dot 3TiO(2) were evaluated at 850 degrees C using wood powder pyrolysis gas produced from a 0.3 kg/h screw pyrolyzer with no extra steam, silica sand was selected as an inert material for comparison. The GHSV of the runs were around 2000 h(-1) with tar content of about 200 g/Nm(3). The results suggest that 4Na(2)O center dot 5TiO(2) presents the highest activity, Na2O center dot 3TiO(2) ranks slightly lower, and silica sand shows no activity of enhancing hydrogen yield. The hydrogen formation is promoted through tar cracking, water gas shift and/or methane reforming. The H-2/CO increases to 1.8-2.0, which is higher than that of silica sand (about 0.35) and raw gas (about 0.25). Tar conversion in the 4Na(2)O center dot 5TiO(2) reforming was about 99% and nearly no coke was formed within the test duration of about 8 h, whereas the silica sand was coked obviously in 1 h. Most tar components can be effectively reformed, except for parts of xylene, naphthalene, biphenylene, and anthracene. The activity of 4Na(2)O center dot 5TiO(2) decreases gradually in the long-term test because of the release of sodium and has a tendency to transform to Na2O center dot 3TiO(2), the latter exhibits satisfactory stability and activity.
