Experimental Study of Urotropine Gasification at Different Gas Flux Temperatures

The gasification of a solid porous fuel during the filtration of high-temperature gaseous products through it is experimentally studied. A sublimating material, urotropine, is used as a solid fuel. It is shown that with an increase in the initial temperature of the filtered gas, the time of urotropine gasification decreases and the intensity of the fuel gasification process increases, which leads to an increase in the flow of urotropine gasification products. In the temperature range of 470 to 500 K, intensive gasification of urotropine occurred, while the temperature of the outgoing gaseous products changed slightly. The hydrogen content in gaseous products reached 7 vol %.
