Abstract:
A channel reactor arrangement for contacting reactant with a particulate catalyst, indirectly heat exchanging the reactants with a heat transfer fluid and replacing catalyst particles on stream, said arrangement comprising:a) a reactor vessel; b) a plurality of reaction stacks located in said reactor vessel comprising a plurality of parallel plates extending vertically and horizontally and defining heat transfer channels and reactant channels in each reaction stack; c) openings for passing a reactant stream through said reactant channels and a plurality of manifolds, each manifold in communication with reactant channels in less than all of the reaction stacks for collecting the fluid flow from the reactant channels, an outlet defined by each manifold and a valve for regulating the flow from each outlet independently of a valve on an outlet defined by another of said plurality of manifolds; d) a catalyst distributor at the top of each reaction stack, a catalyst collector at the bottom of each reaction stack and each reaction stack including a dedicated valve for selectively controlling the addition and withdrawal of catalyst particles from each reaction stack; and e) means for passing a heat exchange fluid through the heat exchange channels of each reaction stack.
