In this study, titanium chips (TC) generated from industrial facilities was utilized as TiO2 support for hydrogenation of carbon dioxide (CO2) to methyl alcohol (CH3OH) over Cu-based catalysts. Nano-sized CuO and ZnO catalysts were deposited on TiO2 support using a co-precipitation (CP) method (CuO-ZnO/TiO2), where the thermal treatment of TC and the particle size of TiC2 are optimized on CO2 conversion under different reaction temperature and contact time. Direct hydrogenation of CO2 to CH3OH over CuO-ZnO/TiO2 catalysts was achieved and the maximum selectivity (22%) and yield (18.2%) of CH3OH were obtained in the range of reaction temperature 210-240 degrees C under the 30 bar. The selectivity was readily increased by increasing the flow rate, which does not affect much to the CO2 conversion and CH3OH yield.
在本研究中，将工业设施产生的钛屑（TC）用作TiO₂载体，用于在铜基催化剂上进行二氧化碳（CO₂）加氢制甲醇（CH₃OH）。采用共沉淀（CP）法（CuO-ZnO/TiO₂）将纳米级CuO和ZnO催化剂负载在TiO₂载体上，其中在不同反应温度和接触时间下，对TC的热处理和TiC₂的粒径进行了CO₂转化率优化。实现了在CuO-ZnO/TiO₂催化剂上CO₂直接加氢制CH₃OH，在30巴压力下，反应温度210-240℃范围内获得了甲醇的最大选择性（22%）和产率（18.2%）。通过增加流速可使选择性容易提高，而这对CO₂转化率和CH₃OH产率影响不大。
