天然气蒸汽转化壳层催化剂孔结构测定

Pore structure characterization of shell construction catalysts for steam reforming of natural gas

介绍用压汞法测定壳层催化剂活性部份孔结构的方法,提出了计算公式,讨论压汞试验误差,比较了混合样品的测定值和计算值,表明该方法适用。

In the paper,a method and formulas for determination of pore size distribution of active shell part in shell construction catalysts by mercury porosimetry are proposed. Experimental errors from mercury porosimetry are examined and values of determination and calculation of specific pore volume for the mixed samples are compared. The results obtained shows the method to be applicable.
