Fluid catalytic cracking process for cracking multiple feedstocks

A fluid catalytic cracking process for cracking multiple feedstocks in a fluid catalytic cracking apparatus comprising a riser, the process comprising:

• injecting from first distributor tips of a first set of feed distributors positioned around a perimeter of the riser, a first feed into a region of lower catalyst density in the riser;
• injecting from second distributor tips of a second set of feed distributors
• positioned around the perimeter of the riser, a second feed into a region of higher catalyst density in the riser,
• wherein the second distributor tips are spaced apart from the first distributor tips at a vertical distance of no more than about an inner diameter of the riser;
• and
• cracking the first feed and the second feed in the riser in the presence of a fluid catalytic cracking catalyst to provide a cracked effluent stream.

A fluid catalytic cracking process for cracking multiple feedstocks in a fluid catalytic cracking apparatus comprising:

• a riser, the riser comprising a first set of feed distributors having first distributor tips and a second set of feed distributors having second distributor tips positioned around the perimeter of the riser, the process comprising:
• injecting from the first distributor tips of the first set of feed distributors, a first feed into the riser;
• injecting from the second distributor tips of the second set of feed distributors, a second feed into the riser,
• wherein the first distributor tips are positioned at a first radius in the riser and the second distributor tips are positioned at a second radius with respect to a center point of the riser,
• wherein the first distributor tips are located in a region of a lower catalyst density in the riser and the second distributor tips are located in a region of a higher catalyst density in the riser;
• and
• cracking the first feed and the second feed in the riser in the presence of a fluid catalytic cracking catalyst to provide a cracked effluent stream.
