What is the relationship between reactor penetration time?
Thread Content
Could everyone help analyze this: what is the reactor penetration time, and what is its relationship with the amount of recycled hydrogen? And what is the relationship with the airspeed?
It should be inversely proportional, right? The higher the air velocity and the greater the amount of recycled hydrogen, the shorter the penetration time should be; it’s also related to the catalyst bed
The reactor penetration time is related to the cyclic hydrogen pressure, being inversely proportional to it； It is proportional to the pressure drop across the catalyst bed.
The bed penetration time is proportional to the amount of recycled hydrogen; the greater the amount of recycled hydrogen, the faster the penetration time. The main function of circulating hydrogen is to remove the heat of reaction. And space velocity refers to the amount of feed oil that passes through the catalyst per unit of time. The higher the airspeed, the faster the passage time. The shorter the residence time. The penetration time is faster.
