Abstract��
Based on the properties of carbonaceous catalyst,composition of feed gas and the size parameters of reforming reactor,heat and material balance of reactor were established.Because of irregular carbonaceous catalyst with size distribution,the fluid resistance in reforming reactor has been studied.The results indicate that: 1) The generated heat of CO and H2O is the main source of release of heat,accounting for 71.03% of heat input.The main heat absorption reaction is the transformation of CO2 and CH4,whose heat is about 33.54% of heat output.The heat of high temperature gases is about 54.11% and heat dissipation is 13.51%;2) Fluid resistance of carbon catalyst beds is the main part of the fluid resistance in reforming reactor.The bigger carbonaceous catalyst particle is,the smaller fluid resistance of carbonaceous catalyst bed is.The best granulometric composition of carbonaceous catalyst is 25—35 mm of 80%,15—25 mm of 15% and 5—15 mm of 5%,and fluid resistance of carbonaceous catalyst bed is 313.5 Pa /m.
