Blast furnace gas ash (BFGA) contains high amounts of metal oxides such as Fe, Ca, Na and other active substances. In this paper, the possibility of BFGA as an effective and low-coat catalyst for the decomposition of biomass pyrolysis has been explored based on the high content of iron oxides for high yield of gas and low yield of pyrolysis oil from biomass. The effects of temperature and BFGA on the yield and properties of pyrolysis products were discussed. The variation of pyrolysis gas composition and low heating value of BFGA with temperature was analyzed. The results clearly indicate that adding BGFA to pine pellets can effectively decrease the liquid yield and significantly enhance the yield of pyrolysis gas. The production of H₂ in pyrolysis gas can effectively increase by 5.16 % and 2.06 % respectively with the action of #1 BFGA and #2 BFGA compared with CK. It suggests that two kinds of BFGA can reduce the content of oxygen-containing functional groups and effectively degrade organic substances. This experimental results show that BFGA has the potential to be used as an effecient catalyst with excellent stability and realize the effective utilization of waste resources.

高炉烟灰（BFGA）包含大量的金属氧化物，例如Fe，Ca，Na和其他活性物质。在本文中，基于高含量的氧化铁以产生高产气和低产自生物质的热解油，探索了BFGA作为分解生物质热解的有效和低涂层催化剂的可能性。讨论了温度和BFGA对热解产物产率和性能的影响。分析了热解气体成分和BFGA的低发热量随温度的变化。结果清楚地表明，向松丸中添加BGFA可以有效降低液体收率并显着提高热解气的收率。H _2的产生与CK相比，＃1 BFGA和＃2 BFGA的作用可有效提高热解气体中的气体含量，分别提高5.16％和2.06％。这表明两种BFGA可以降低含氧官能团的含量并有效降解有机物。实验结果表明，高炉煤气有潜力用作高效催化剂，具有优异的稳定性，并实现废物资源的有效利用。
