Hydrocracker feed specification
Hydrocracker feed specification
(OP)
I wonder about hydrocracker (Hydrocracking Process) feedstock specification. Does anybody know practical values to be assumed for HCC run-length of 2 years ? Feedstock to be considered is vacuum gasoil and coker gasoil.





RE: Hydrocracker feed specification
From my old notes the influence of nitrogen in feedstock on zeolite-based catalysts was as follows:
ppm cat aging, oC/day
650 to 750 0.05 to 0.06
~1200 0.14
It appears that ammonia may neeutralize acid sites.
