Tributylamine (TBA) was found to be effective in promoting the cracking of heptane. The conversion of heptane and the yield of gas product are both distinctly accelerated. The selectivity of propylene is remarkably promoted compared with that by cracking pure heptane at 550°C, while at the higher temperature of 600°C, the selectivity of all gas products changes very little. The cause to this effect...
Triethylamine was found to be effective in promoting the cracking of heptane at the temperature of 550–650°C. The experimental yields of ethylene and propylene are more than twice as high as the calculated values on hypothesis of no interaction between triethylamine and heptane, when the mass fraction reaches 6% at the most notable temperature of 550°C. The accelerating mechanism is studied by gas...
