What is the effect of lengthening the pre-raising section in catalytic cracking (coaxial) units? Thank you!

The catalyst is transported in a two-stage dense phase flow, resulting in an uneven radial distribution. The function of the pre-lift section is to make the catalyst flow more uniformly and achieve a better distribution, thereby creating better conditions for the catalyst-oil contact reaction

It is mainly for the sake of improving the catalyst distribution!

The poster is saying that the feed nozzle has been moved up by 2 meters, right?
