In reactors with internal heat removal, how are the reaction components introduced into the reaction zone?

• The location of component introduction depends on the specific reaction.

• Only cold feedstock is introduced from below.

• Only reaction products are introduced from below.

• All reaction components are introduced from below.

• Half of the components are introduced from above and half from below.

What is a disadvantage of reactors with internal heat removal?
