Process for catalytically NH3 Drive natural gas comprising O2 Rich gas auto Thermal Reformer, cool,Lead to a catalytic conversion of synthesis gas to be converted to separate washing gaseous CO2, co and CH4, contacting the synthesis gas with liquid N2 in a stage of washing gas.

摘要

The Home is rich in Natural Gas with gas in O2, an autothermal Reformer, which produces a sitesis Gross gas temperatures in the range of 900 to 1200 degrees C.To provide 40 to 100 bar and in the presence of Catalysts of Fission, calculated on dry, present a hydrogen content of 55 to 75% by volume, a co content of 15 to 30% in volume,A CO2 content from 5 to 30% in volume and Volume H2: co ratio of 1.6 to 4.The crude synthesis gas autothermal Reformer Cools,Driving through a catalytic converter for the conversion of co and H2 is a converted synthesis gas containing H2, calculated on DryAt least 55% in volume and a co content of up to 8% by volume.The synthesis gas is subjected to a gas purification of several Stages for the separation of CO2, co and CH4,We obtain a mixture of n2 and H2 which leads a ammonia synthesis Catalyst for production of Ammonia.Ammonia can be obtained in the synthesis of ammonia from urea, at least partially, by reaction with CO2.
