摘要：The reaction of hydrocracker bottom hydroisomerization and hydrocracking was studied in a fixed bed micro reactor over a commercial catalyst. Normal hexadecane Was used as model compound to judge the reactivity of the catalyst. Then, hydrocracker bottom was investigated, and the reaction liquid products were collected and distillated into light and heavy fractions for detailed investigation. Hydrocarbon types and carbon number distribution of them were fully analyzed. Results indicate that normal paraffins are easy to be hydroconverted into isoparaffins or small molecules. Isoparaffins and monocycloalkanes have similar hydroisomerization and hydrocracking properties. Fused cycloalkanes are hard to be cracked. Hydroconversion of normal paraffins, isoparaffins and monocycloalkanes dominate the reason of the drop of VI and pour point. (C) 2009 Elsevier B.V. All rights reserved
