Plastic conversion feed system

A process for transporting a feedstock to a reactor vessel comprising:

• physically breaking up said feedstock in a homogenizer, said feedstock comprising a plastic, a hydrocarbonaceous material, or any combination thereof;
• a pelletizer, said pelletizer reducing the size of said feedstock thereby producing pelletized feedstock, wherein the pelletizer is located downstream from the homogenizer, wherein the pelletizer operates at a temperature that ranges between ambient to about 160° F. (71.1° C.);
• an extruder located downstream from the pelletizer and receiving the pelletized feedstock, and a feed conduit operatively connecting said extruder to said reactor vessel, and
• extruding said pelletized feedstock into a continuous mass of feedstock that is fed into said reactor vessel, wherein the extruder heats the pelletized feedstock so that the continuous mass of feedstock exiting the extruder has a temperature that ranges from about 200° F. (93.3° C.) to about 400° F. (204.4° C.),
• wherein said feed conduit is configured to develop a vapor seal with the feedstock being fed into said reactor vessel, said vapor seal being located around said feed conduit at an entrance to said reactor vessel to prevent a product vapor formed in said reactor vessel from flowing backwards into said extruder.

A plastic conversion feed system for transporting a feedstock to a reactor vessel, comprising:

• a size reduction device comprising of a shredder or a pelletizer or both a shredder and pelletizer capable of reducing the size of or densifying or both reducing the size of and densifying said feedstock comprising a plastic, or a hydrocarbonaceous material, or any combination thereof;
• a heating device located downstream from the size reduction device, the heating device capable of heating the feedstock at a temperature that ranges between 200° F. (93.3° C.) to about 400° F. (204.4° C.), and transferring said reduced sized feedstock to an extruder,
• wherein the extruder is located downstream from the heating device,
• wherein the extruder heats the feedstock so that the feedstock exiting the extruder has a temperature that ranges from about 200° F. (93.3° C.) to about 400° F. (204.4° C.), said extruder having an output axis;
• and
• a feed conduit that extends from said extruder to said reactor vessel, wherein said feed conduit is configured to develop a vapor seal with the feedstock being fed into the reactor vessel said vapor seal being located around said feed conduit at an entrance to said reactor vessel to prevent a product vapor formed in said reactor vessel from flowing backwards into said extruder.

A process for transporting a feedstock to a reactor vessel comprising the steps of:

• reducing the size of said feedstock in a size reduction device;
• the size reduction device comprising of a shredder or a pelletizer or both a shredder and pelletizer, said feedstock comprising a plastic, or a hydrocarbonaceous material, or any combination thereof;
• heating the feedstock at a temperature that ranges between 200° F. (93.3° C.) to about 400° F. (204.4° C.), and
• extruding said pelletized feedstock into a continuous mass of feedstock that is fed into said reactor vessel, wherein the extruder heats the pelletized feedstock so that the continuous mass of feedstock exiting the extruder has a temperature that ranges from about 200° F. (93.3° C.) to about 400° F. (204.4° C.),
• wherein said feed conduit is connected to said reactor vessel,
• wherein said feed conduit is configured to develop a vapor seal with the feedstock being fed into said reactor vessel, said vapor seal being located around said feed conduit at an entrance to said reactor vessel to prevent a product vapor formed in said reactor vessel from flowing backwards into said extruder, and
• feeding said feedstock to said reactor vessel.
