Fluidized solids distributor

1. A solids distributor system comprising:

a vessel and

a solids distributor disposed within the vessel, wherein the solids distributor comprises a side entry spent catalyst distribution system comprising:

a solids standpipe positioned along a first central axis;

a gas line positioned along a second central axis;

a solids transfer line in fluid communication with the solids standpipe and the gas line and positioned along a third central axis;

a center conduit;

a distributor in fluid communication with the center conduit positioned along a fourth central axis and in fluid communication with the solids transfer line, the distributor comprising one, two, three, four, five, six, seven, eight, nine, ten, eleven, or twelve conduit arms and each of the arms comprising slots disposed on the bottom of the arms;

wherein the fourth central axis is inclined or declined at an angle in the range of from 45 to 90 degrees with respect to the third central axis; and

a gas grid disposed within the internal chamber of the vessel.

2. The solids distributor system of claim 1 , wherein the distributor comprises four arms.

3. The solids distributor system of claim 1 , wherein the arms comprise open ends.

4. The solids distributor system of claim 1 , wherein the slot has a tapered geometry.

5. The solids distributor system of claim 1 , wherein the vessel comprises an FCC regenerator.

6. The solids distributor system of claim 1 , further comprising a support system.

7. The solids distributor system of claim 6 , wherein the support system comprises beams, triangular trusses, cross beams, or tension beams.

8. A method of distributing fluidized solids comprising:

providing a solids distributor system, wherein the solids distributor system comprises a vessel and a solids distributor disposed within the vessel, wherein the solids distributor comprises a side entry spent catalyst distribution system comprising: a solids standpipe positioned along a first central axis; a gas line positioned along a second central axis; a solids transfer line in fluid communication with the solids standpipe and the gas line and positioned along a third central axis; and a distributor in fluid communication with a center conduit positioned along a fourth central axis and in fluid communication with the solids transfer line, the distributor comprising one, two, three, four, five, six, seven, eight, nine, ten, eleven, or twelve conduit arms and each of the arms comprising slots disposed on the bottom of the arms;

wherein the fourth central axis is inclined or declined at an angle in the range of from 45 to 90 degrees with respect to the third central axis;

a gas grid disposed within the internal chamber of vessel, and

flowing solids and gas through the solids distributor into the vessel.

9. The method of claim 8 , wherein the solids distributor system comprises the solids distributor system of claim 1 .
