【Learning Ethylene Together】Five questions per day to easily learn about ethylene. 57 31. The higher the degree of cracking, the greater the conversion rate of the feedstock, as well as the amount of H2 and CH4 produced; consequently, the gas yield increases. 52. If the pressure in the cracking furnace drum is high, the outlet temperature of TLE rises rapidly. 53. The cracking reactions of n-alkanes mainly involve bond-breaking reactions and dehydrogenation reactions; from a thermodynamic perspective, dehydrogenation reactions are more likely to occur. 54. During the cracking of heteroalkanes, bond breaking is more difficult than dehydrogenation reactions. 55. The coking mechanism of the ethane furnace is roughly the same as that of the diesel furnace. 31. The higher the pyrolysis depth, the higher the conversion rate of the feedstock, as well as the amounts of H2 and CH4 produced; consequently, the gas yield increases. √ 52.
