Abstract:

采用棉杆生物质废弃物为原料、H3PO4为活化剂,在流化床中化学活化制备棉杆活性炭,并将其作为载体负载Co-B组分,制备了棉杆活性炭基Co-B催化剂(Co-B/C)。以该催化剂应用于硼氢化钠水解制氢,系统考察了活性炭活化条件(活化温度、活化时间、活化剂用量mH3PO4/mCS)、水解反应温度及催化剂循环使用次数对催化产氢性能的影响。同时,使用N2物理吸附、FTIR、XRD和SEM等技术对活性炭载体及催化剂进行了表征。结果表明:在活化温度500℃、活化时间1h、mH3PO4/mCS为0.75条件下制得的活性炭载体,负载14.5%Co的催化剂表现出最佳催化性能:反应温度为25℃时,平均产氢速率可以达到12.06L·min-1·(gCo)-1,催化剂表现了较高活性。催化产氢反应的活化能为44.61kJ·mol-1。循环使用5次后,催化剂仍保持初次活性的54%。
