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.
