1) twice decomposition
二次裂解
1.
To get clean hydrogen-rich gas from biomass,an innovational process of hydrogen production by pyrolysis and twice decomposition was introduced,which realized the deep conversion of hydrocarbons to decrease tar sharply and improve hydrogen yield.
采用生物质热解及二次裂解的方法制取富氢气体。
2) Primary pyrolysis
初次裂解
3) three breakup
三次裂解
4) secondary crack
二次裂纹
5) over-cracking
二次裂化
1.
As disengager contains a large volumne space in which the oil vapor flows at lower velocity and resides for a longer time,the over-cracking of oil vapor occurs and the liquid droplets in oil vapor and catalyst particles tend to deposit on the internal wall of disengager to form coke.
但沉降器存在的大空间却形成了油气的滞留空间,油气流速低,停留时间长,结果导致反应油气的二次裂化反应,油气中的液滴和催化剂颗粒易于沉积在沉降器器壁上结焦形成焦块。
