    Abstract: Process for the catalytic dehydrogenation of a C2 or C3 alkyl aromatic in which a feedstock containing the alkyl aromatic and steam is supplied into the inlet of a tubular reactor containing a dehydrogenation catalyst. Within the reactor, the feedstock flows through at least a portion of the reactor along a spiral flow path extending longitudinally of the reactor. The resulting vinyl aromatic product is then recovered from a downstream or outlet section of the reactor. The spiral flow path through which the feedstock is passed is located at least adjacent the inlet side of the reactor and at least a portion of the spiral flow path contains a particulate dehydrogenation catalyst. The spiral flow path may extend throughout a major portion of the elongated tubular reactor and may contain a particulate dehydrogenation catalyst in a substantial portion there. The feedstock containing the alkyl aromatic and steam is supplied into a plurality of tubular reactors located within the interior of a dehydrogenation reactor vessel and is arranged in a parallel relationship in which the tubular reactors are spaced laterally from one another and from the interior wall of the reaction vessel.

    Abstract: A catalyst bed is made of a monolith having a plurality of pores extending through the monolith, the pores forming tortuous flow paths through the monolith. The tortuous flow paths are obtained by modifying the monolith channels with turbulence-inducing objects or means. Catalyst is disposed on the wall surfaces formed by the pores. Reactants are passed through the tortuous flow paths creating turbulent flow thereby increasing the contact of the reactants with the catalyst on the wall surfaces and the mixing across the reactant stream.
