| Abstract: | The reasons were analyzed for rapid in- crease of pressure drop in a reformer feed hydrore- fining reactor, and the preventive measures were pro- posed. The mass fractions of sulphur and iron in the scale sample of hydrorefining reactor were 47.57% and 48.43 % , respectively, and the rapid increase of pressure drop in the reactor was attributed to the sol- id deposits on catalyst surface. |
