<p>A process fluid is purified of strongly acidic impurities, preparatory to treatment over a catalyst or over a hydrogen sulphide absorbing material, by contact with one or more alkali metal aluminates, preferably a beta alumi aluminate. Such aluminates have a high capacity for absorbing hydrogen halides. The process fluid is especially a naphtha hydrocarbon to be reacted with steam to give a gas of high methane content.</p> |
