摘要：根据裂解油实际碳链组成,选取不同碳链长度(碳数n=2N,N=4~8)的烯烃,研究4种不同金属催化剂对烯烃加氢的催化作用。结果表明,PdC对烯烃加氢具有较好的催化效果。H2常压的条件下,以24 g正庚烷为溶剂,烯烃6 g,PdC用量3%(质量分数),在35℃条件下反应60 min,直链烷烃的产率大于99%。在此基础上,研究地沟油裂解油的催化加氢。在35 g裂解油中加入质量分数为3%的PdC,在H2初始压力6 MPa,反应温度100℃,反应时间120 min。气相色谱-质谱联用仪(GC-MS)分析裂解油加氢前后的组分变化,结果表明加氢后裂解油中的烯烃含量从35.46%降至2.01%,燃料油的稳定性得到提高。
The pyrolysis oil obtained by the catalytic cracking of waste oil is an important substitution of fossil oil,and consists of alkanes,alkenes,carboxylic acids and ketones,whose carbon chain length ranges from C8 to C24. Due to the high olefins content,the pyrolysis oil is unstable and needs further stabilization study on the hyrogenation of the olefins.According to the actual carbon chains of pyrolysis oil,different carbon chain lengths(carbon number n = 2 N,N = 4-8)of olefins were selected as model compounds for hydrogenation in the presence of four different metal catalysts. The results show that the PdC is more efficient for the hydrogenation of olefins. At 3% wt of PdC,6 g of olefins was dissolved into 24 g of n-heptane and reacted at 35 ℃ for 60 min with constant hydrogen pressure,yielding corresponding alkanes over 99%.When 35 g pyrolysis oil from waste oil was chosen for hydrogenation,3% wt of PdC was added and the reaction was performed at initial hydrogen pressure of 6 MPa,100 ℃ for 120 min. GC-MS analysis indicates that the content of olefins in the pyrolysis oil significantly decreased from 35.46% to 2.01%,and therefore enhanced the stability of pyrolysis oil.
