Abstract:
？co-ni/al2o3catalystwaspreparedbythefusionmethodandusedinfischer-tropschsynthesis（fts）.thecatalystswerecharacterizedbymeansofnitrogensorptionandscanningelectronmicroscopy.theeffectofsomereactionconditionssuchastemperature，pressureandh2/cofeedratioonthecatalyticperformanceofco-ni/al2o3incohydrogenationwasinvestigatedinafixed-bedreactor.theresultsindicatethattheoptimumreactionconditionsare250℃，0.3mpa，h2/cofeedratioof2.0，andghsvof3000h-1.kinetically，thereactionratewascorrelatedwiththelangmuir-hinshelwood-hougen-watsontypemodels.theactivationenergyforthebestfittedmodelis88.41kj/mol，suggestingthattheintra-particlemasstransportisnotsignificant.
