✦ Synopsis

Reliable procedures are described for the analysis of alkali metal sulphate-promoted vanadium pentoxide catalysts supported on silica gel. Vanadium and alkali metals are determined by flame atomic absorption spectrometry in suitable dilutions of solutions obtained by digestion with sulphuric and hydrofluoric acids. "Free acidity" is dctermined by dissolution of the samples in alkali and hack-titration with acid; corrections for V,O, acidity are included. Relative standard deviations are about 2.5% for metal contents of 3--5% (w/w).

Air-gasification at low temperatures (733-773 K) of chars from Spanish coals catalysed by V,O, has been studied and the results have been compared with those obtained previously using copper as catalyst. Under the reaction conditions, both catalysts showed high activity due to their ability to under
