CATALYTIC REACTOR AND VEHICLE EQUIPPED WITH SAID CATALYTIC REACTOR

摘要

A catalytic reactor includes a catalytic reaction section, which has a purification catalyst for gas purification, and a warming-up section, which is located at a position capable of heat-exchanging with the purification catalyst and has a chemical heat storage material that generates heat when ammonia is fixed and absorbs heat when ammonia is desorbed. The catalytic reactor is further includes an ammonia supply section, which has an adsorbent capable of adsorbing ammonia and transfers ammonia to and from the warming-up section through the adsorption and desorption of the ammonia, and an ammonia depressurization section, which has an ammonia fixation section for fixing ammonia and reduces the partial ammonia pressure of at least the interior of the warming-up section after ammonia is desorbed from the chemical heat-storage material.

1. A catalytic reactor comprising:
a catalytic reaction section having a purification catalyst for purifying gas; a warming-up section located at a position capable of heat-exchanging with the purification catalyst, and wherein the warming-up section has a chemical heat storage material that generates heat when ammonia is fixed and absorbs heat when ammonia is desorbed; an ammonia supply section having an adsorbent capable of adsorbing ammonia, wherein the ammonia supply section transfers ammonia from and to the warming-up section by adsorption and desorption of ammonia; and an ammonia depressurization section that has an ammonia fixation section for fixing ammonia and reduces an ammonia partial pressure at least in the warming-up section after the desorption of ammonia from the chemical heat storage material.
