摘要:建立了较完整的估计重油和沥青中饱和碳浓度的方法,其中包括环烷桥头碳、环烷甲基取代碳、环烷烷基(≥C_2)取代碳等.基于理论分析,建立了估计环间的桥链和各种平均结构参数的方法,包括平均芳环环核数和环烷环环核数、芳环和环烷环烷基取代度、单元片上芳环和环烷环数.从实验数据出发,提出了烷基链长分布的公式.
An unprovcd method is developed for characterizing saturated carbons includ-ing naphthcnic internal carbons ,methyl and alkyl(≥C_2)substituted naphthenic carbons etc inhcavy oils and bitumens·Based on theoretical analysis ,the methods are established for evalu-ating bridges between rings , avarage structural parameters such as avcrage numbers of aro-matic and naphthenic ring nuclei,degrees of alkyl substitution on aromatic and naphthenicrings , numbcrs of aromatic and naphthenic ring in a sheet.T he formula on alk yl chainlength distribution is proposed,according to Strausz's experimental data.
