Robinson Brothers offers extensive know-how and expertise in large scale catalytic hydrogenation processes.

Robinson Brothers dedicated hydrogenation facilities include an extensive array of specially designed pressure autoclave reactors ranging from R&D to large scale, which incorporate the latest computer controlled operating systems.

Manufacturing capabilities include:

  • Large scale hydrogenation autoclave reactors from 900L to 2,250L fabricated in glass-lined, carbon steel and stainless steel
  • Development scale hydrogenation autoclave reactors from 100ml to 1L
  • Fabricated in stainless steel and Hastelloy
  • Operable over a wide range of pressures and temperatures, if required at upto 70bar pressure and temperatures upto 170°C
  • A range of transition metal and precious metal catalysts are used e.g Palladium (Pd), Platinum (Pt), Nickel (Ni), Ruthenium (Ru), and Rhodium (Rh)

Robinson Brothers has particular experience in the use of sponge Nickel and Carbon supported Palladium catalysts for hydrogenation reactions. In case of Palladium catalysts, our ownership of the precious metal content allows tight management, control and optimisation of hydrogenation process economics.

Hydrogenation autoclaves at Robinson Brothers are linked to arrays of flexible multi-purpose reactors for both upstream/downstream processing, product work-up and isolation. We also have segregated solids handling facilities – typically having Rosenmund Guedu enclosed filter driers and final product packing area’s equipped with laminar flow booths.

Robinson Brothers key technologies include:

  • Reductive amination: a range of speciality amine products are produced typically by the reaction of benzaldehyde’s with alkyl amines to form intermediate imines, followed by subsequent catalytic hydrogenation to yield the amine.
  • Selective catalytic reduction of naturally derived raw materials, e.g. phytochemicals & botanicals used for the production of intermediates and additives for the food, beverage, aroma and cosmetic markets.
