Patent ID: 8703060

Claim:
A catalyst-testing apparatus including: a tubular heater 1 for vaporizing water, preheating gas and controlling the temperature for reaction, wherein the tubular heater 1 is made with an internal diameter of 52 to 78 mm and a length of 160 to 240 mm; a U-shaped reactor 2 made of quartz including an inlet, an outlet and a catalyst zone 21 located between the inlet and the outlet and comprising a quartz pipe located between two round masses of quartz filaments and configured for receiving catalyst 9 , wherein the U-shaped reactor 2 is located in the tubular heater 1 except the inlet and the outlet, wherein the U-shaped reactor 2 is made with an internal diameter of 8 to 12 mm, an external diameter of 9.6 to 14.4 mm and a length of 720 to 1080 mm; a thermocouple 22 connected to the catalyst zone 21 through the outlet of the U-shaped reactor 2 ; a gaseous mass flow controlling assembly 3 connected to the inlet of the U-shaped reactor 2 for feeding natural gas and air into the U-shaped reactor 2 in a quantitative manner; a liquid flow controller 4 connected to the inlet of the U-shaped reactor 2 for feeding liquid water into the U-shaped reactor 2 in a quantitative manner so that the liquid water travels down an internal side of the U-shaped reactor 2 and gets heated and turned into steam during the travel so that the steam, the natural gas and the air react with one another; two pressure gauges 5 respectively connected to the inlet and outlet of the U-shaped reactor 2 for measuring pressure difference between the inlet and outlet of the U-shaped reactor 2 to determine whether there is efflorescence of the catalyst 9 or precipitation of carbon from the catalyst 9 that would stick to the internal side of the U-shaped reactor 2 and cause the pressure to increase in the U-shaped reactor 2 ; a cooler 8 connected to the outlet of the U-shaped reactor 2 for cooling and condensing resultant gas from the U-shaped reactor 2 ; a separator 6 connected to the cooler 8 , wherein liquid is separated from gas and the gas is dried in the separator 6 ; and a chromatograph 7 connected to the separator 6 , wherein the gas is analyzed to reveal the composition of the gas.
