发明名称 METHOD FOR THE PRODUCTION OF MELAMINE
摘要 The invention relates to a method for the production of melamine by reaction of urea in the presence of a solid catalyst in one or more serial reactors in the temperature range 370 °C to 430 °C, cooling and filtering the gases produced in the urea reaction, separation of the melamine by desublimation and recycling a part of the gases produced after separation of the melamine ('recycle gas') into the reactor or reactors, characterised in that all given steps are carried out at a pressure in the range 4 bar to 10 bar.
