Abstract (en)
[origin: WO0185607A1] The invention relates to a gas generator, especially for generating treatment gas containing CO and H2, for heat treating metallic material at high temperatures. Said gas generator comprises at least one catalytic retort and has means for heating at least partial areas of the catalytic retort(s). According to the invention, the catalytic retort is divided into at least two retort areas (1, 2a, 2b, 2c) and at least one of the retort areas (1), preferably the retort area (1) located first in the direction of flow-through, is configured so that it can be removed from the gas generator. The invention also relates to a method for generating a treatment gas, which contains CO and H2, for heat treating, especially for carburizing and hardening, metallic material at high temperatures in which the treatment gas is formed on the basis of the catalytic reaction of a hydrocarbon gas with carbon dioxide, oxygen and/or with a gas mixture containing oxygen, whereby the catalytic reaction is carried out in a catalytic retort. The invention also provides that the catalytic reaction is carried out in a catalytic retort that is divided into at least two retort areas (1, 2a, 2b, 2c).
