چکیده
|
A new molybdenum phosphide (mop) catalyst was successfully synthesized for co2 reforming of ch4 reaction. the catalysts were prepared by temperature-programmed reduction (tpr) of phosphomolybdate precursors which were modified by citric acid (ca) at the molar ratio of mop:ca = 1: x (x = 0,1.0,2.0,3.0),which were characterized by means of x-ray diffraction(xrd),n2 adsorption-desorption and co2-tpd techniques. the results showed that the addition of citric acid can affect the catalytic activity and that the mop catalyst had the highest catalytic activity at 1073 k and x=1. after reduced in h2 flow at 923 k,the activity of the post-reaction catalyst can be well restored,while its structure remains unchanged. in higher temperatures,the samples exhibit good anti-sintering ability and stability. © 2016,chemical society of pakistan. all rights reserved.
