以干污泥、木屑等生物质为原料，研究了催化蒸汽重整对焦油气化的影响。以含萘模拟气体为焦油，研究了以wo3为抗硫助剂的Ni/ MgO-CaO（基于白云石）催化剂的焦油重整特性。结果表明，所研制的催化剂具有较高的萘重整活性，在含硫化氢气体中也很稳定。与几种工业蒸汽重整催化剂相比，该催化剂还表现出优异的抗焦化和抗硫中毒性能。
Gasification of tar by catalytic steam reforming was examined in the gasification process of biomass, such as dried sewage sludge and wood chips. The tar reforming characteristics of the newly-developed Ni/MgO–CaO (based on dolomite) catalyst which was doped with WO3as a sulfur-resistant promoter, was investigated using a simulated gas containing naphthalene as tar. The result has confirmed that the developed catalyst shows a high naphthalene reforming activity and is stable even in gas containing hydrogen sulfide. The catalyst also exhibited superior resistance to coking as well as sulfur poisoning compared to several commercial steam-reforming catalysts.
