摘要: Bioleaching of spent hydrotreating catalyst by thermophillic archae Acidianus brierleyi was investigated. The (containing Al, Fe, Ni and Mo as major elements) characterized, the effect pretreatment (decoking) on two-step medium leaching examined at 1% w/v pulp density. Decoking resulted in removal carbonaceous deposits volatile impurities, affected solubility metal compounds through oxidization sulfides. Nearly 100% extraction achieved using for Mo, 67% Al. reduced nickel concentration leachate below regulated levels safe waste disposal. Chemical (i.e. abiotic) equimolar sulfuric acid produced bacteria during process a lower efficiency (by up to 30%). Results indicated that A. successfully leached heavy metals from catalyst.
