摘要
分别以Fe-Zn-Zr和Fe-Zn-Zr/HY为催化剂,以CO2,CO和H2为反应物,在340℃,5MPa的反应条件下,通过进行对比实验,研究和探讨了CO和CO2催化加氢反应过程的不同.结果表明,对于CO2加氢来说,CO2与CO之间的转化不是生成目的产物烃类的必要步骤;无论对于CO2还是CO加氢,异构烃主要在HY分子筛上生成.
Parallel experiments were conducted to investigate the performance of COz hydrogenation and CO hydrogenation over Fe-Zn-Zr catalyst and Fe-Zn-Zr/HY composite catalyst respectively at 340℃, 5.0 MPa. The difference between COz hydrogenation and CO hydrogenation was studied. The results showed that the conversion from COz to CO was not the indispensable step for the hydrocarbons synthesis via COz hydrogenation. And for whether COz hydrogenation or CO hydrogenation, iso-alkanes were mainly synthesized over HY zeolite.
