Abstract
A hydrocarbon gas detection system utilizes a heat chamber or oven to maintain the system at a temperature that will support cracking of hydrocarbon gases. A gas chamber which is located inside the oven is used to contain the flow of gases under analysis and to pass these gases over a first temperature sensing device. A catalyzing material is associated with the first temperature sensing device, either by placing it very near the temperature sensing device or by coating the temperature sensing device with the catalyzing material. A second temperature sensing device is located inside the heat chamber or oven, either outside the gas chamber, or inside the gas chamber, but separated from the first temperature sensing device. The output of the first and second temperature sensing devices extend outside of the furnace to measurement and/or display instrumentation. With this system, the gas sample under analysis is passed through the gas chamber and brought into contact with the first temperature sensing device. The catalyzing material associated with the first temperature sensing device causes cracking of any hydrocarbon gases. This cracking reaction changes the temperature of the first…
