The effect of vanadate speciation on the redox kinetics and process performance of the British Gas Stretford Process
In order to distinguish essays and pre-prints from academic theses, we have a separate category. These are often much longer text based documents than a paper.
The kinetics and mechanism of the oxidation of proposed vanadium (IV) species at conditions prevalent in the Stretford desulphurisation process have been investigated in this study. The British Gas Stretford Process employs vanadate to oxidise hydrogen sulphide to elemental sulphur, and the vanadium (IV) formed by the process is reoxidised to vanadium (V) by air oxidation in the presence of a catalyst.
