The Normal feed for FCC unit is HVGO & HCGo from coker. In case of HCGO not processed
1) Can we get Regenrator temperature?
2) what is the behaviour of FCC unit?

Not having HCGO in the feed will probably reduce the coke make and make it more difficult to achieve the catalyst heat compared to your normal operation. However, many FCCs run without coker material so you should be able to make it work. You should talk to your licensor or other FCC experts and go over the detailed analysis of the feeds and the heat balance.

Regenerator temperature depends on coke deposited on catalyst. Coke is dependent on number of factors such as:
Reactor temperature, higher the temperature greater is the coke,
Catalyst to Oil ratio, higher the catalyst to oil greater is the conversion too,
feed preheat temperature,
type of the feed stock, aromatic and olefinic streams form greater coke,
recycle streams also could lead more coke,
management of MTC,
type of the regenerator etc.
Number of parameters are interdependent. Detailed information is required to come to some reasonable conclusion
