摘要:
采用钨酸盐/H2O2/N-甲基吡咯烷酮硫酸氢盐([HNMP][HSO4])体系对模拟燃油和实际燃油进行深度催化氧化脱硫研究。采用X线衍射仪(XRD)、傅里叶红外光谱仪(FT-IR)以及热分析仪(TG)对合成的2种Keggin型钨酸盐(烷基硅钨酸铵(Q4SiW)和烷基磷钨酸铵(Q3PW))进行表征。考察不同脱硫体系、不同催化剂、催化剂用量、H2O2用量、反应温度和不同硫化物等对模拟油脱硫效果的影响。结果表明:在反应温度60 ℃,反应时间4 h,模拟油3 g,[HNMP][HSO4] 1 g,n(O):n(S):n(催化剂)=300:50:1,Q4SiW为催化剂条件下,此催化氧化体系对噻吩(TS)、苯并噻吩(BT)和二苯并噻吩(DBT)的脱硫率分别为54.2%、87.4%以及99.1%,且重复使用5次,催化氧化性能并未明显降低。
Abstract:
Desulfurization from model oils and actually oils by catalytic oxidation with tungstate/H2O2/N-methyl pyrrolidonium hydrosulfate([HNMP][HSO4])was studied.Two Keggin-type tungstates,alkyl silica ammonium tungstate(Q4SiW)and alkyl ammonium phosphotungstate(Q3PW),were characterized and analyzed by X-ray diffraction(XRD),Fourier transform infrared spectrum(FT-IR), and thermogravimetric analysis(TG). And different influencing factors were investigated,including different desulfurization systems,different catalysts,reaction temperature and variety of S-compounds as well as the amount of H2O2 and the catalyst.Results showed that the sulfur removal reached 54.2%,87.4% and 99.1% under the conditions: reaction temperature was 60 ℃,reaction time was 4 h, m(mode oil)=3 g, m([HNMP][HSO4])=1 g, the molar ratio of n(O):n(S):n(catalyst)=300:50:1,and the catalyst of Q4SiW.The tungstate/H2O2/[HNMP][HSO4] system could be recycled 5 times without a significant decrease on the desulfurization efficiency.
