结果表明，在催化剂的程序升温还原过程中，CuO和ZnO表面吸附的CO2可进行加氢反应和逆水汽变换反应。

The results revealed that the reactions of hydrogenation and RWGS of CO 2 proceeded on the surface of both CuO and ZnO .

结果表明，CO能占据催化剂表面部分CO2的吸附位，能抑制CO2加氢的逆水汽变换反应和促进甲醇含成，从而大大提高了CO2加氢合成甲醇的选择性和收率。

由于存在逆水煤气反应和Boudouard反应，CO2能显著促进乙烷的脱氢反应。

The dehydrogenation of ethane was enhanced by CO2 because of the existence of the reverse water gas shift reaction and the Boudouard reaction .

结果表明，CO占据了部分催化剂表面起逆水汽变换反应的活性位，从而降低CO2转化率，但甲醇选择性和收率得到了提高。

The results indicate that CO may capture a small amount of active sites on the catalyst surface which bring about the reverse water gas shift reaction . Thus the conversion of CO 2 is suppressed , but the selectivity to and yield of methanol are improved .

CO2对乙苯脱氢的显著促进作用要归因于金属氧化物催化剂的氧化还原机制以及乙苯脱氢和逆水煤气变换反应耦合的协同作用。

The mechanism of CO 2 oxidation is also discussed . It can be concluded that the remarkable promoting effect of CO 2 on the dehydrogenation of EB is due to both redox cycle of oxide catalyst and coupling of EB with reversed water gas shift reaction .

过量的MgO助剂对催化剂的反应性能产生负面影响，MgO的碱性可以促进逆水煤气变换反应，从而导致H2选择性降低和CO选择性提高。

In addition , the basicity of MgO promoted the reverse water-gas shift reaction , which led to the increase of CO selectivity and the decrease of H_2 selectivity . The suitable content of MgO promoter in Ni / Al_2O_3 catalyst was about 7 % .
