TiO_2/Al_2O_3复合载体用于有机硫加氢转化催化剂的研究

Study on the TiO_2/Al_2O_3 complex supporter adopted in catalyst for hydroconversion of organic sulfur

研究了不同TiO2 含量对有机硫加氢转化催化剂活性的影响 ,并与单一Al2 O3 作载体的催化剂进行了性能对比。结果表明 ,用TiO2 /Al2 O3 复合载体制得的有机硫加氢转化催化剂 ,性能明显改善 ,对噻吩的平均转化率由原 34 .73%提高到 6 7.5 2 % ;催化剂预硫化所需硫化剂量可减少 5 0 %以上。

The influence of the content of TiO 2 in complex supporter on the activity of catalyst for hydroconversion of organic sulfur was studied, and the performance comparison was made between TiO 2/Al 2O 3 complex supporter and Al 2O 3 unitary one. The result showed that the performance of the catalyst for hydroconversion of organic sulfur with TiO 2/Al 2O 3 as complex supporter was improved obviously, the conversion of thiophene increased from 34.73% to 67.52%,the amount of sulfurize agent for catalyst pre sulfurize was reduced by 50%.
