A method and apparatus for concurrently catalytically reacting fluid streams and distilling the reaction product. A catalytic structure is provided within a distillation column reactor and includes mass transfer devices presenting hollow spaces and a fixed catalyst bed formed from solid catalyst particles. The mass transfer devices are interconnected gas and liquid permeable elements. The liquid phase preferentially flows along channels formed in the catalyst bed before contacting the devices for mass transfer with the vapor phase which primarily flows through the devices.

Structure and method for catalytically reacting fluid streams in mass

A concurrent catalytic reaction with distillation structure involves a plurality of vapor permeable plates which are arranged in spaced apart relationship with a catalyst placed in the open space between two adjacent plates. The catalyst filled area presents a reaction zone where catalytic reaction can take place and the vapor permeable plates present a large surface area for vapor and liquid phase exchange. The invention also encompasses a process for concurrent catalytic reaction with distillation employing structure as aforedescribed and including the steps of feeding a liquid stream to a column employing such structure and directing the stream through the catalytic reaction zone while concurrently distilling a portion of the liquid to present a vapor stream which is directed in countercurrent relationship to the liquid stream flow.
