Distribution and yield rates of products (figures 3 to 6) are as expected considering the reaction within the cracker at different crude,pitch.feed rates. As the pitch is heated it begins to vaporize, and the turbulenc'e of the vapors splashes some of the iluid onto the hot wall where it sticks and is coked. If enough heat is available, the rest of the pitch is vaporized and cracked. ' As the cracked materiais leave the hot zone, heavy high-b
