Abstract
The petroleum refining processes and of oil shale industrialization
generate solid and semi-solid residues. In those residues heavy metals are found
in concentrations that vary according to the production sector. The destination of
those residues is encouraging researches looking for new technologies that reach
the specifications of environmental organisms, and are being developed and
applied to the industry. In this work it is shown that the heavy metals
concentrations, previously in the petroleum oily solid residues and in those of the
oils shale, treated by low temperature thermal conversion, obtaining in both
cases concentrations below Ippm to Nickel and below 5ppm to vanadium.
