What is the approximate decomposition temperature of ammonia? What is the melting point of alumina? Coke oven gas has a calorific value of 4200 kcal. What is its maximum combustion temperature? Can coke oven gas burn and dissolve alumina without adding pure oxygen??????
For the purpose of decomposing ammonia to generate a nitrogen-hydrogen mixture, a catalyst is added, and the temperature is generally controlled at about 800 degrees Celsius.
Ammonia: Main ingredients: Pure product appearance and properties: Colorless, pungent odorous gas. pH: Melting point(℃): -77.7 Boiling point (℃): -33.5 Relative density (water=1): 0.82(-79℃) Relative vapor density (air=1): 0.6 Saturated vapor pressure (kPa): 506.62(4.7℃) Heat of combustion (kJ/mol): No data critical temperature (℃): 132.5 Critical pressure (MPa): 11.40 Log value of octanol/water partition coefficient: No data available Flash point (℃): Meaningless ignition temperature (℃): 651 Explosion upper limit% (V/V): 27.4 Lower explosion limit%(V/V): 15.7 Solubility: Easily soluble in water, ethanol and ether. Main purpose: Used as refrigerant and preparation of ammonium salt and nitrogen fertilizer. Main components of alumina: Pure product appearance and properties: White powder. pH: Melting point(℃): 2010-2050 Boiling point (℃): 2980 Relative density (water=1): 3.97-4.0
