摘　　要：采用粉末X射线衍射分析法(PXRD)鉴定了德士古重油气化炉炉渣中晶体物相。其晶体主要物相鉴定结果为莫来石(Al6Si2O13)、绿镍矿(NiO)和铁镍矿(FeNi3);次要物相为磁赤铁矿(Fe2O3)。能量色散X射线分析器(EDS)和X射线荧光光谱仪(XRF)均检出炉渣含铝、硅、氧、镍、铁等。本试验对德士古重油气化炉结渣故障技术分析和技改具有指导意义。The phase of crystalline compounds in clinker of Texaco's furnace for heavy oil gasification process was identified by powder X-ray diffraction analysis method(PXRD).The major phases are mullite(Al6Si2O13),bunsenite or nickel oxide(NiO) and awaruite(FeNi3);the minor phase is maghemite(Fe2O3).Aluminium,silicon,oxygen,nickel and iron elements were detected by EDS and XRF in the clinker.This experiment has a guidance significance for the slagging technical analysis and technical improvements of Texaco's furnace for heavy oil gasification process.
