Non-aromatic Carbon Study for Light Gas Oil of Cracking Feed by NMR |
| |
| Abstract: | ~(13)C NMR is used for studying the type of non-aromatic carbon and structure of aliphatic carbon present in six kinds of light diesel oil as feedstocks for crack-ing.An equation for calculating the percentage of aliphatic carbon in longstraight chains and substituted long straight side chains as well as the averagechain length existed in the cracking feedstocks has been obtained by correlatingC-distribution determined by NMR,and the contents of paraffins(P),naphthenes(N)and aromatics(A)by mass spectrography.The calculated results are comparedwith those from capillary chromatography.This study is significant to under-standing the properties and selection of cracking feedstocks. |
