摘要： The invention relates to a method for treatment of a fluid quantity including chemical reacting means such as combustible materials above a certain minimum quantity in a catalytic device (1). The method comprises the steps of entering said fluid quantity into the catalytic device (1) through an inlet (2), controlling the temperature in one or more passage sections (3, 5) of said catalytic device (1) including at least one reaction passage section (4), by heat transferring, and emitting the treated fluid quantity from the catalytic device through an outlet (28). The invention also relates to a catalytic device and uses of the method and the catalytic device.

摘要： The invention relates to a catalytic device with internal heat exchange that among other things can be used for vehicles with an internal combustion engine or for stationary engines where there is a certain amount of unburned gas components in the exhaust that can be converted in the catalyst. By the invention it is obtained that the maximum temperature in the catalyst is always nearly constant whatever the inlet temperature. Hereby, the catalyst can be designed to work at a very specific temperature, by which it is possible, partly to ensure a better and safer burnout of the unburned components, and partly to save expenses for catalyst materials. The exhaust gas is guided through the catalyst by at least three passage sections that have a mutual internal heat exchange. In the main reaction passage section there are catalytic materials of one or several kinds, in which the gas can react, and in which the gases heat exchange with the succeeding main heat transfer passage section passage.

摘要翻译： 本发明涉及具有内部热交换的催化装置，其特征在于可以用于具有内燃机的车辆，或者用于在排气中可以转化为催化剂的一定量的未燃气组分的固定发动机。 通过本发明，得到的是，无论入口温度如何，催化剂中的最高温度总是几乎恒定。 因此，催化剂可以设计成在非常特定的温度下工作，由此可以部分地确保未燃烧组分的更好和更安全的烧尽，并且部分地节省催化剂材料的费用。 废气通过至少三个具有相互内部热交换的通道部分被引导通过催化剂。 在主反应通道部分中存在一种或多种催化材料，其中气体可以反应，并且其中气体与随后的主传热通道部分通道热交换。
