An improvement in fluid-bed oxychlorination methods comprising in combination a generally cup-shaped container and an inverted generally cone-shaped gas distributor having a truncated apex the section of truncation defining a generally circular or polygonal opening, the lip portion of the container

An improvement in fluid-bed oxychlorination methods comprising in combination a generally cup-shaped container and an inverted generally cone-shaped gas distributor having a truncated apex the section of truncation defining a generally circular or polygonal opening, the lip portion of the container fitting against the similarly-shaped opening of the distributor.

In a method of chlorinating a member of the group consisting of aliphatic hydrocarbons having 1 to 2 carbon atoms, their incompletely chlorinated derivatives and benzene by passing a member of the group to be chlorinated, oxygen and a chlorinating agent selected from the group consisting of chlorine

In a method of chlorinating a member of the group consisting of aliphatic hydrocarbons having 1 to 2 carbon atoms, their incompletely chlorinated derivatives and benzene by passing a member of the group to be chlorinated, oxygen and a chlorinating agent selected from the group consisting of chlorine, HCl and mixtures of chlorine and HCl in the vapor phase through a fluidized bed of metal halide catalyst particles, the improvement comprising fluidizing the particles by employing a gas distribution system comprising in combination: (a) a generally cup-shaped container having a generally circular unobstructed mouth portion defined by an outer lip portion and a base portion; (b) pressurized gas introduction means for the introduction of the gas within the container substantially vertically through a tube directed toward the base portion; (c) a generally inverted cone-shaped gas distributor having a truncated apex defining a generally circular opening; (d) means for holding the outer lip portion of the container in a periferally closed relationship with the opening defined by the truncated apex of the cone-shaped distributor; so that when in an operating mode the metal halide catalyst particles are distributed uniformly and suspended generally above the cone-shaped distributor by the pressurized gas.
