Methods and apparatuses for upgrading a pyrolysis oil stream and a hydrocarbon stream are provided. In an embodiment, a method for upgrading a pyrolysis oil stream and a hydrocarbon stream includes providing the pyrolysis oil stream and providing the hydrocarbon stream separate from the pyrolysis oil stream. The pyrolysis oil stream and the hydrocarbon stream are introduced into a reaction zone. Deposits form adjacent to a pyrolysis oil outlet of the pyrolysis oil stream. The pyrolysis oil stream and the hydrocarbon stream are catalytically cracked in the presence of a particulate cracking catalyst in the reaction zone. During catalytic cracking, the pyrolysis oil deposits adjacent the pyrolysis oil outlet of the pyrolysis oil stream are removed, such as with a cleaning head.
