Abstract

Homogeneous catalysis of the water-gas shift reaction has been accomplished by the use of solutions of CuCl2·2H2O in aqueous pyridine and other substituted pyridine (methyl pyridines or dimethylpyridine) solutions. This system is stable, low active catalyst displaying turnover frequencies for hydrogen production (TF(H2)) of about 6 moles H2 per mole Cu per day for [Cu] = 20 mM, P(CO) = 1.9 atm and T= 120°C. © 1998 Elsevier Science Ltd.
