采用浸渍法制备了Mo-Cu/HZSM-5松木屑热转化催化剂。采用BET、XRD和TEM等手段对Mo-Cu/HZSM-5催化剂和HZSM-5进行了表征。结果表明，CuO的引入有利于MoO 3在HZSM-5中的分散。将Mo-Cu/HZSM-5催化剂与两段催化裂解系统相结合，用于松木屑的热转化。这些产品包括天然气、生物油和生物炭。通过气相色谱（GC）分析气体。采用气相色谱-质谱联用技术（GC-MS）对生物油中的化合物进行了鉴定。测定了生物油的含水量、高热值和粘度。测定了生物质炭的HHV和元素。结果表明，Mo（3%）-Cu（3%）/HZSM-5处理的生物质热解产物中C6-C12烃类含量最高，表现出较强的甲烷转化能力，且在相同热解条件下，不同处理的生物质热解产物的性质无显著差异。(C)2015爱思唯尔有限公司版权所有。
Mo-Cu/HZSM-5 catalysts for pine sawdust thermal conversion were prepared using an impregnation method. The Mo-Cu/HZSM-5 catalysts and HZSM-5 were characterized by Brunauer-Emmett-Teller (BET), X-ray diffraction (XRD) and transmission electron microscopy (TEM). All characterization results indicated that the introduction of CuO is beneficial to the dispersion of MoO3 in the HZSM-5. Combined with the two-stage catalytic pyrolysis system, the Mo-Cu/HZSM-5 catalysts were used for pine sawdust thermal conversion. The products included gas, bio-oil and bio-char. The gas was analyzed by Gas chromatography (GC). Gas chromatography-mass spectrometry (GC-MS) was used to identify the compounds in bio-oils. The water content, higher heating value (HHV) and viscosity of bio-oils were measured. The HHV and elements of bio-char were determined. The results indicated that Mo(3%)-Cu(3%)/HZSM-5 treatment yielded the highest amount of C-6-C-12 hydrocarbons, showed a robust ability to convert methane in the gas to bio-oil, and displayed no significant difference in the properties of bio-char when compared to different treatments in the same pyrolysis conditions.
