a$)$ Calculate weight of catalyst in each reactor, if it is divided equally into

three reactors.

b$)$ Calculate the length of time between regenerations.Question # $3$

A petroleum refinery is planning regeneration schedule for reformer catalyst. The

catalyst deactivates after processing $250$ barrels of feed per $kg$ of catalyst.

Following information about feed and catalyst is given:

Feed rate $=5500BPSD$

Feed API gravity $=52\mathrm{.}5$

Catalyst bulk density $=820k\frac{g}{m^3}$

Liquid hourly space velocity $(LHSV)=3\mathrm{.}5\frac{v}{h}\frac{r}{V}$
