The flow of spent catalyst to the regenerator is regulated by a slide valve in the spent catalyst line. Since the cracking reactions produce some carbonaceous material (referred to as catalyst coke) that deposits on the catalyst and very quickly reduces the catalyst activity, the catalyst is regenerated by burning off the deposited coke with ...
The refinery's workflow uses highly efficient thermic, catalytic, and hydrogenation processes. The refinery's equipment produces Euro-4 and Euro-5 fuels, boiler fuel, and a liquefied gases. To achieve 100% output of Euro-4 and Euro-5 gasoline, a catalytic cracking gasoline hydrotreater for removal of sulfur compounds is under constructed.
The Soviet oil industry eventually did obtain much of their technology from foreign companies, largely American ones. [4] At about that time, fluid catalytic cracking was being explored and developed and soon replaced most of the purely thermal cracking processes in the fossil fuel processing industry. The replacement was not complete; many ...
Needle coke, also called acicular coke, is a highly crystalline petroleum coke used in the production of electrodes for the steel and aluminium industries and is particularly valuable because the electrodes must be replaced regularly. Needle coke is produced exclusively from either fluid catalytic cracking (FCC) decant oil or coal tar pitch.
