Hot regenerated catalyst
The combined feed begins to crack when it contacts hot catalyst in the riser , and continues cracking
until ___ - (ANSWER)The oil vapors are disengaged from the catalyst in the reactor
These cracked products flow in a ____ phase through the reactor vapor line to the main fractionating
column . - (ANSWER)Vapor
Because catalytic cracking reactions are ___ energy must be continuously supplied to sustain the
cracking reactions in the reactor - (ANSWER)Endothermic
This additional energy is imported as heat to the reactor by transfer of ____ from the catalyst
regeneration section - (ANSWER)Hot catylist
The catalyst has two functions in the Reactor ( 55R - 101 ) to ___and to act as a ___ . -
(ANSWER)Promote cracking reactions
Heat transfer agent
In Reactor ( 55R - 101 ) , catalyst is referred to as " Spent " when ___ (the carbon residue of the
processed feed stock) is deposited on the catalyst as a resulting of the cracking process - (ANSWER)Coke
Spent catalyst exits the bottom of Reactor ( 55R - 101 ) and flows into the middle of the Regenerator /
Combustor ( 55R - 104 ) where it will be ___ - (ANSWER)Regenerated and Re-heated
The phrase "Regenerating the catalyst " actually refers to the___ - (ANSWER)Separation of coke from
