摘　　要：The inlet temperature of the Vacuum Gas Oil(VGO)hydrotreating reactor of a refinery is analyzed with the integration of multiple series reactors and hydrogen network considered.The effect of the inlet temperature(T1)on hydrogen sinks/sources and the product output is analyzed systematically based on the simulation of the series reactors,including VGO hydrotreating reactor,hydrocracking reactor,fluid catalytic cracking reactor and visbreaking reactor.The general relation between the Hydrogen Utility Adjustment(HUA)and multiple pairs of varying sinks and sources is deduced,and correlations between varying streams and T1 are linearly fitted.Based on this,the quantitative equation between HUA and T1 is derived,and corresponding diagram is constructed.The T1 corresponding the minimum hydrogen consumption is identified to be 345°C.The inlet temperature of the Vacuum Gas Oil（VGO） hydrotreating reactor of a refinery is analyzed with the integration of multiple series reactors and hydrogen network considered.
