Abstract
A method for the contamination-free heating of a highly pure gas to a temperature of from 300 to 1200° C. involves passing the highly pure gas at a pressure of from 0.1 to 10 bar abs. over a highly pure solid which does not contaminate the gas, the solid being present in a highly pure container whose wall consists of a material which has a transparency of more than 85% for infrared rays and the container being irradiated by means of the infrared rays, the solid being heated thereby and the solid heating the gas.
Claims12
A method for the contamination-free preheating of a highly pure gas prior to introducing the heated gas into a reactor, comprising passing highly pure gas at a pressure of from 0.1 to 10 bar abs over a highly pure solid which does not contaminate the gas and does not react with the gas, the solid being present in a highly pure container whose wall has a transparency of more than 85% for infrared rays and the container being irradiated by means of the infrared rays, the solid being heated thereby and the solid heating the gas to form a heated gas having a temperature of from 300° C. to 1200° C., the container being filled with the highly pure solid, which comprises granules, fragments or shaped articles, such that the solid is immobile in the container and the gas to be heated can flow around said solid.
