| Abstract: | Experimental research on influence of sample pretreatment method on the result was made in this paper when denitration catalyst was tested by mercury intrusion method. Three different sample pretreatment methods were adopted for denitration catalyst used in a power plant in Beijing to test pore volume,pore size and other pore structure parameters with mercury intrusion method. Influence of sample pretreatment method on result repeatability was analyzed as well as its reasons and applicability. |
