METHOD OF VAPOUR REFORMING AND DEVICE FOR ITS IMPLEMENTATION

摘要

FIELD: chemistry. ^ SUBSTANCE: invention relates to two methods (two variants) of reforming process using oxidizing gas at temperature 980-1000C. The recirculation of the flow part outgoing from the autothermic reformer to the flowrate vapour-hydrocarbon is described at that the said recirculation is implemented throught the instrumentality of thermocompressor ejector using heated beforehand supplied mix as operative fluid. For the optimization of general configuration the mole ratio of recirculating synthesis gas and operative fluid was chosen in the range 0.2-1.0. In order to prevent the carbon black formation in the reforming process recirculated hydrogen and vapour are fed to the input flow and the temperature of feeding is increased. Since there is a certain pressure drop between initial mixture of vapour and natural gas and the mix fed to reformer it is necessary to increase the pressure of initial mixture but it is compensated with the lower pressure drop in the heater and other equipment laid out upstream and downstream because of decreasing of vapour capacity. ^ EFFECT: reforming process is carried out without carbon black formation. ^ 27 cl, 2 dwg, 1 tbl
