Claim:
A detachable reductant decomposition reactor comprising: a middle tube portion formed with a reductant injector mount that is configured to introduce a reductant into the reactor; an inlet tube formed at a first end of the middle tube portion that is configured to create a sealed connection to a first portion of an exhaust system; an outlet tube formed at a second end of the middle tube portion that is configured to create a sealed connection to a second portion of the exhaust system; and a mixer fit at the second end of the middle tube portion adjacent to the outlet tube that is configured to decompose the reductant in an exhaust stream; wherein the injector mount includes an injector chamber and a tube like section separate from the injector chamber, the injector chamber including a first end connected to the middle tube portion and a second end connected to an injector port, the tube like section including a first opening directly communicating with the middle tube portion and a second opening directly communicating with the injector port, the tube like section configured to reduce recirculation flow patterns in the reactor and reduce the formation of reductant deposits.
