| Abstract: | The theoretical backgrounds and methods for measurement of surface(interfacial) tension were reviewed.Methods that suitable for the measurement of surface tension under high temperature,high pressure,influence of different gases,as well as dynamic surface tension measurement were discussed in detail.Issues to be paid attention during the establishment of surface tension measuring device and the factors that effects the accuracy of the measurement result as well as the development trend of surface tension measurement methods were also described.In order to examine the influences of hydrogen and/or other gases on the surface tension measurement result in coal liquefaction processes and petroleum hydrogenation processes,it is recommended to adopt maximum bubble pressure method and/or pendent drop method. |
