Abstract

ABSTRACT Refinery wastes generated in conventional crude oil refining processes, or in accidental situations, are complex substrates for treatment and disposal. Petroleum desulphurisation catalysts can also be hazardous refinery waste. They contain various metals, such as cobalt, molybdenum, nickel and tungsten. In this paper, three petroleum refiner’s spent desulphurisation catalysts were investigated. These catalysts were not suitable for recycling and, therefore, were classified as hazardous waste. They were chemically characterised, including phase composition and their effect on a consortium of microorganisms used in the process of bioremediation. Catalysts contained up to 2.26 g kg−1 of total petroleum hydrocarbons, up to 56.7 g kg−1 of iron, 18.6 g kg−1 of molybdenum, and less than 0.1 mg kg−1 each of cobalt and nickel. These obtained results show that bioremediation of such waste is possible.

炼厂废脱硫催化剂中重金属对微生物的影响

在常规原油精炼过程中或在意外情况下产生的炼油厂废物是复杂的处理和处置基质。石油脱硫催化剂也可能是危险的炼油厂废物。它们含有各种金属，如钴、钼、镍和钨。以三家炼油厂的废脱硫催化剂为研究对象。这些催化剂不适合回收利用，因此被列为危险废物。它们进行了化学表征，包括相组成及其对生物修复过程中使用的微生物财团的影响。催化剂中总石油碳氢化合物的含量高达2.26 g kg - 1，铁的含量高达56.7 g kg - 1，钼的含量为18.6 g kg - 1，钴和镍的含量均低于0.1 mg kg - 1。这些结果表明，对这类废物进行生物修复是可能的。

期刊介绍： Chemistry and Ecology publishes original articles, short notes and occasional reviews on the relationship between chemistry and ecological processes. This journal reflects how chemical form and state, as well as other basic properties, are critical in their influence on biological systems and that understanding of the routes and dynamics of the transfer of materials through atmospheric, terrestrial and aquatic systems, and the associated effects, calls for an integrated treatment. Chemistry and Ecology will help promote the ecological assessment of a changing chemical environment and in the development of a better understanding of ecological functions.
