초록

Method for initiating operation of an autothermal reformer including the steps of preparing a hot gas which is rich in hydrogen by contacting a methanol and steam containing feed gas with a methanation catalyst and introducing the hot gas into the autothermal reformer, thereby heating the reformer with heat contained in the hot gas to a temperature which is sufficiently high to initiate and maintain subsequent reforming reactions to be carried out in the reformer.

청구항

[ What is claimed is:] [1.] A method of initiating operation of an autothermal reformer comprising the steps of:(a) preparing a hot gas rich in hydrogen by contacting a methanol and steam containing feed gas with a methanation catalyst, said hot gas being at a temperature sufficient to initiate and maintain a reforming reaction; and(b) introducing the hot gas into the autothermal reformer, thereby heating the reformer with heat contained in the hot gas to a temperature which is sufficiently high to initiate and maintain subsequent reforming reactions to ...
