5.Under the condition of non-hydrogen,RON number of the upgraded gasoline has been increased by 30 units with reforming and isomerizing reaction and the contents of benzene and olefin have been slightly increased. The aromatics content is less than 30%, upgraded gasoline yield is 73. 12%, LPG yield is 24.26% , dry gas and the loss are 2. 62%.
原料在非临状态下,经过重整和异构化反应,改质汽油的辛烷值提高30个单位,苯、烯烃含量略有升高,芳烃含量小于30%,改质汽油收率73.12%,液化石油气收率24.26%,干气及损失2.62%。收藏指正
6.The base peak(HOC4H8 m/z 73) was produced by acleavage,hydroxy transferring and loss of C7H14CN. The ions of (CnH2nC=NOH)+ and (CnH2nC=NOH)+ arise from a-cleavage of cyclododecanoe oxime. After the hydrogen of hydroxy was substitued with RC(O)O,the a-cleavage of carbonyl group and the benzyl cleavage were more importance.
对环十二酮肟(A)及其行生物(B1~B9)进行了EIMS裂解规律的研究,十二酮肟环开裂后主要形成CnH2n-1C=NOH及CnH2nCNOH系列的离子,羟基转移后脱C7H14CN形成基峰.羟基原子被OC(O)R取代后,取代基的a位及等基裂解成为主要方式。收藏指正
