Ramakrishnan Ramachandran, Rustam H Sethna, Satish S Tamhankar: Production of terephthalic acid. The BOC Group, Coleman R Reap, Salvatore P Pace, December 2, 1997: US05693856 (48 worldwide citation)

Terephthalic acid is produced by reacting paraxylene with oxygen in a reactor having several vertical stages, the reaction taking place in the liquid phase using acetic acid as solvent and a cobalt-manganese-bromine complex catalyst. During the reaction, a carbon dioxide-containing gas phase is with ...

Divyanshu R Acharya, Satish S Tamhankar: Process and apparatus for the separation of gases. The BOC Group, Coleman R Reap, Salvatore P Pace, September 30, 1997: US05672196 (20 worldwide citation)

Hydrocarbon gas is separated from a gas mixture by concentration swing adsorption in a system consisting of a pair of adjacent adsorption beds that are contained in a cylindrical vessel and separated by a flat partition wall. The system is operated with the beds out of phase, such that one bed is in ...
