摘要 |
Synthesis of small quantities of compounds such as methanol from reagents, especially radio-labelled reagents such as <11>C oxides, in a carrier gas by a catalytic reaction using a catalyst that has been pre-conditioned for the reaction by previous use for the desired reaction and has then been passivated, or has been maintained in the pre-conditioned state, until contacted with said carrier gas. Where the product is adsorbed by the catalyst, it may be desorbed by heating or displaced by contacting the catalyst with a material, e.g. a catalyst poison that is more strongly adsorbed. Such a more strongly adsorbed material may react with the adsorbed catalytic product to produce a desired product.
