More Information
Summary:The method for regenerating molecular sieve by using ammonia pyrolysis gas is characterized by using ammonia pyrolysis gas with temp. of 4 deg.C and pressure of about 1.5 MPa and progressively heating the ammonia pyrolysis gas to 288 deg.C according to the temperature-rising speed to make molecular sieve implement regeneration. Said invention fully utilizes the ammonia pyrolysis gas discharged inthe course of production, can save production time by at least 12 hr. and can greatly reduce fuel consumption.
