Abstract
Nickel catalysis has been studied for coal tars and graphite carbon to produce CH4 methane in the presence of hydrogen. Nickel forms mixed complexes with le g and bpycoline (P.F. Neson: 1988). In this work, we have focused on the mineral part formed mainly by calcite, dolomite, pyrite and other mineral compounds, with the aim of understanding the influence of nickel sulfide as an additive during the hydrotreatment of this mineral matrix from the Tarfaya (Morocco) oil shale under dynamic conditions. The techniques adopted in this study are true thermogravimetry (Red-Croft), calorimetry (DCE) coupled in Red-Croft, X-ray diffraction and dispersive X-ray diffraction coupled by scanning electron microscope. Carbonate decomposition activity was observed during this nickel sulfide addition, preventing in situ decomposition of NiSO4, 6H2O in the presence of hydrogen, and increasing conversion of calcite, dolomite, kaolinite and quartz.
