Ni/TPC催化剂的制备、表征及在秸秆热解燃气重整中的应用
Preparation and characterization of Ni/TPC catalyst and applied in straw pyrolysis gas reforming
摘要
Abstract
Tire pyrolysis char (TPC) was used as a carrier to prepare Ni/TPC catalyst by homogeneous precipitation method.The characteristic of synthetic catalyst was determined by EDX, SEM, XRD, TG and BET.Meanwhile, the performance of Ni/TPC catalyst including reforming temperature, holding time, nickel loading and usage time on the straw pyrolysis gas reforming was investigated in a tube furnace.The results showed that TPC was rich in char and metal.Ni was well loaded on TPC which had a good thermal stability with a specific surface area of 62 m2/g.The Ni/TPC catalyst could obviously improve the burning gas content.The highest catalytic efficiency was obtained at reforming temperature of 750 ℃ and 10 min holding time with 30% Ni loading.The content of H2in the gas was high and relatively increased by 50% after using the catalyst for 850 min.The Ni3ZnC0.7 active component structure converted to FeNi3after long-term used with high and stable catalytic activity.TPC had the ability to be a new type of carrier for nickel catalyst.关键词
