The effects of preparative variables of the supported Mo catalyst on the properties of adsorp-tion and reaction were studied by the CRCT at 250-290°C under atmospheric pressure.The resultsshow that the Mo content and sulphurization temperature mainly affect the number of adsorption sitesof thiophene and the match of adsorbed thiophene and hydrogen.The calcination temperature influencesnot only the numbers and nature of adsorption sites of thiophene but also the turn-over frequency ofsurface reaction of adsorbed thiophene,which increases largely with calcination temperature,becausethe interaction of metal-support is stronger at higher calcination temperature.The results also show thatthe Mo content of monolayer capacity,sulphurization at 400°C and calcination at 500°C would lead toan optimum match of adsorbed thiophene and hydrogen,i.e.the highest reaction rate and the lowestactivation energy of reaction would be obtained under these treatment conditions.
