1. A process for fluid catalytic cracking, comprising: providing a stream through a plurality of distributors to a riser terminating in a reaction vessel wherein the plurality of distributors comprises a first distributor set comprising at least two distributors positioned around a perimeter of the riser, a second distributor set comprising at least two distributors positioned around the perimeter of the riser, and a third distributor set comprising at least two distributors positioned around the perimeter of the riser; wherein the third distributor set is positioned above the second distributor set and the second distributor set is positioned above the first distributor set; and the at least two distributors of the third distributor set are radially staggered from the at least two distributors of the second distributor set and the at least two distributors of the second distributor set are radially staggered from the at least two distributors of the first distributor set. 2. The process according to claim 1, further comprising fourth and fifth distributor sets each having at least two distributors wherein the fifth distributor set is above the fourth distributor set, and the fourth distributor set is above the third distributor set. 3. The process according to claim 2, wherein each distributor set is radially staggered from an adjacent distributor set. 4. The process according to claim 3, wherein the first distributor set comprises five distributors, the second distributor set comprises five distributors, the third distributor set comprises five distributors, the fourth distributor set comprises four distributors, and the fifth distributor set comprises four distributors. 5. The process according to claim 1, further comprising a fourth distributor set of at least two distributors wherein the fourth distributor set is above the third distributor set. 6. The process according to claim 5, wherein the first distributor set comprises five distributors, the second distributor set comprises five distributors, the third distributor set comprises four distributors, and the fourth distributor set comprises four distributors. 7. The process according to claim 1, wherein the respective distributors of the first and second distributor sets are positioned evenly around the perimeter of the riser. 8. The process according to claim 7, wherein the distributors of the second distributor set are offset by about 18° with respect to the distributors of the first distributor set. 9. The process according to claim 5, wherein a vertical distance between the third and fourth distributor sets is greater than a vertical distance between the first and second distributor sets. 10. The process according to claim 1, wherein the distributors, independently, are positioned about 10-about 170° from vertical. 11. A fluid catalytic cracking apparatus, comprising: a riser terminating in a reaction vessel, wherein the riser comprises: 1) a first distributor set comprising at least two distributors positioned around a perimeter of the riser at a first elevation;2) a second distributor set comprising at least two distributors positioned around the perimeter of the riser at a second elevation; and3) a third distributor set comprising at least two distributors positioned around the perimeter of the riser at a third elevation wherein a first vertical distance between the first and second distributor sets is less than a second vertical distance between the second and third distributor sets; anda regenerator having a regenerator standpipe connected to a bottom portion of the riser;wherein the respective distributors of each distributor set are radially staggered with the distributors of an adjacent distributor set. 12. The apparatus according to claim 11, further comprising a fourth distributor set comprising at least two distributors positioned around the perimeter of the riser at a fourth elevation, wherein a third vertical distance is between the third and fourth distributor sets, and the third vertical distance is greater than the second vertical distance. 13. The apparatus according to claim 11, wherein the first distributor set comprises five distributors, the second distributor set comprises five distributors, the third distributor set comprises four distributors, and the fourth distributor set comprises four distributors. 14. The apparatus according to claim 11, wherein the distributors, independently, are positioned about 10-about 170° from vertical. 15. A fluid catalytic cracking apparatus, comprising: a riser terminating in a reaction vessel, wherein the riser comprises: 1) a first distributor set comprising at least two distributors positioned around a perimeter of the riser at a first elevation;2) a second distributor set comprising at least two distributors positioned around the perimeter of the riser at a second elevation different from the first elevation; and3) a third distributor set comprising at least two distributors positioned around the perimeter of the riser at a third elevation different from the first elevation and the second elevation; wherein the at least two distributors of the first distributor set are radially staggered from the at least two distributors of the second distributor set and the at least two distributors of the second distributor set are radially staggered from the at least two distributors of the third distributor set. 16. The apparatus according to claim 15, further comprising a fourth distributor set comprising at least two distributors positioned around the perimeter of the riser at a fourth elevation, and the at least two distributors of the fourth distributor set are offset with respect to the at least two distributors of the third distributor set. 17. The apparatus according to claim 15, wherein the first distributor set comprises five distributors, the second distributor set comprises five distributors, and the third distributor set comprises for distributors. 18. The apparatus according to claim 15, wherein the first distributor set comprises five distributors, the second distributor set comprises five distributors, and the third distributor set comprises four distributors. 19. The apparatus according to claim 15, wherein the distributors, independently, of the first, second, third, and fourth distributor sets are positioned about 10-about 170° from vertical.
