Reforming catalyst for Methanol steam to hydrogen MWC-612 in atmospheric pressure, 240 ~ 250 ° c. Liquid airspeed (1.5 to 2 hours - 1, methanol conversion rate was 100%. gas, catalyst for methanol decomposition of the syngas in 290 degrees in normal atmosphere. The invention of the products not only can be used to direct methanol fuel battery anode catalyst, at the same time it can also be used for other fuel cell, and gas reforming catalyst, the anode, organic pollutants, and burning, organic synthesis and many other fields.
Liquid airspeed (~ 1-1.5 hours, methanol conversion rate was 100%.On 24-280 degrees, liquid airspeed 1.0 ~ 1.5 hours - 1 conditions, methanol solution (H2O: CH3OH = 2:1, molecular ratio) after gasification by catalyst beds, methanol conversion reaction can be stable in 80% ~ 100%,CO content in reaction < 0.20%. It is a kind of preparation alcohols fuels battery anode PtRu/C dual compound catalysts, involving direct methanol fuel battery anode carbon in preparation of catalysts.
This invention with weak reductant and tin acid containing high alkaline solution of carbon black, make carrier surface active distribution uniformity, Then add high chlorine acid solution .Finally the existence ofa platinum nd ruthenium, can optimize the form PtRu generation of highly dispersed homogeneously, alcohols electricity catalytic oxidation of high activity of nano PtRu/C dual compound catalysts, it will have good alcohols electrical activity in low platinum load conditions , and the catalytic oxidation of CO poisoning has strong ability.
