A fluid bed reactor is provided having a grid baffle structure to provide increased theoretical stages within the reactor to enable the reactor to be used for time/temperature dependent reactions requiring a number of mixing stages and/or an increased particle residence time. The preferred baffle structure comprises a plurality of staggered first and second vertical members extending partly across the reactor from opposed sides of the reactor which form a path for the feed to travel therethrough from the inlet to the outlet of the reactor with the vertical members having vertical cross-members, preferably shorter than the vertical members, extending completely between adjacent vertical members and/or partly in the space between the members to form reaction stage sections whereby feed entering the reactor moves in a serpentine path and/or a sequential underflow and/or overflow path through the reaction stage sections of the baffle from the inlet of the reactor to the reactor outlet.
