Petroleum Coke

Microwave-induced combustion for petroleum coke digestion: a promising sample preparation strategy for subsequent elemental determination

“…As expected, relatively high concentrations were observed for Ni and V. If the samples were considered as anode grade (petroleum coke containing relatively low levels of metals), all of them presented results below the maximum levels; 3,6 for Ni (200–250 ppm), V (350–400 ppm), Fe (350 ppm), Ca and Na (200 ppm), with the exception of sample 2 that presents a slightly higher Ni concentration (210 ppm). It was observed that Ca, Co, Fe, Ni and V presented concentrations higher than LOQs for all the samples evaluated.…”

“…1,2 This material presents a high value for industry and could be used in several applications depending on the impurity levels. 3–5 The presence of metallic impurities could be deleterious and the concentration of some metals must be controlled. 1,3,6 Moreover, it is also mentioned in literature that the processing of petroleum coke could lead to environmental contamination of soil and water with metals, and more studies are still mandatory to evaluate the impact of refining industry.…”

“…However, when high-sulphur feedstock is used, the obtained high-sulphur, low-quality coke is not widely used and stored at the re nery or used as solid fuel. Such application causes environmental problems, so alternative ways of using petroleum coke must be found (Predel, 2014; M. Wu et al, 2005).…”
