摘要:
在超临界CO2状态下,采用镍铝作为催化剂对溶剂油进行氢化,以脱苯率为指标,通过单因素试验和响应面分析对氢化条件进行优化,得到最优氢化条件压力10.2 MPa、温度78 ℃、时间52 min、搅拌速率200 r/min、催化剂添加量4%,氢化后的溶剂油中苯含量小于100 μg/g。将常规氢化和超临界氢化的节能情况进行对比,结果显示:在超临界CO2状态下,以镍铝作为催化剂的氢化更节能。该方法有效的降低了溶剂油中的芳烃含量,拓宽了超临界氢化的应用领域。

Abstract:
Solvent oil, encompassing a group of important products from petroleum that are commonly used in the extraction of edible oils, was hydrogenated by nickel-aluminum catalyst in a supercritical CO2 reactor, and the reaction conditions were optimized using response surface methodology to maximize the removal efficiency of benzene hydrocarbons. Hydrogenation at 78 ℃ and 10.2 MPa for 52 min with stirring at 200 r/min using 4% of the catalyst proved optimal. The content of benzene hydrocarbons in the hydrogenated product was below 100 μg/g. In addition to effectively removing the benzene hydrocarbons in solvent oil, the supercritical CO2-assisted hydrogenation using nickel-aluminum catalyst was energy saving in comparison with the conventional method, broadening its range of application.
Key words: supercritical CO2, nickel-aluminum catalyst, hydrogenation, energy saving
