Patent DE-2544640-A1 (DE)
Title: Electrolysis in fluid bed cell - having conducting particles suspended in electrolyte to carry out reactions
Inventor: FLEISCHMANN MARTIN
IPC: C25B3/29
Filed: 1975-10-06
Abstract: Process for carrying out improved electrochemical reactions uses particles of which at least some are bipolar. Their surfaces at least should be (semi-)conducting. To fluidise them, an electrolytic mixt. is used contg. the reaction components. Inside the fluidised bed in at least part, a potential gradient is maintained. The particle sizes, conductivity, flow velocity of the electrolyte and reaction partners, and the voltage gradient are so selected that at elast some of the at least partially conducting particles have anodic and cathodic surfaces. Also the electrode potential at these surfaces is such that the chemical reactions occur at them, or only part of their surface. The particles can have a core of non-conducting material with a covering of >=1 layers of conducting material. A typical process is the electrolysis of sea water to make hypo-chlorite. Similarly it can be used to make hypobromite from NaBr and the decarboxylation of monomethyladipate to dimethyl sebacate.
