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.
硫酸镍水合物对塔尔法亚矿床(摩洛哥)不同油页岩层的加氢分解的反应影响
已对镍催化煤焦油和石墨碳在氢气存在下产生 CH4 甲烷进行了研究。镍与 le g 和 bpycoline 形成混合络合物(P.F. Neson:1988 年)。在这项工作中,我们重点研究了主要由方解石、白云石、黄铁矿和其他矿物化合物形成的矿物部分,目的是了解在动态条件下对塔尔法亚(摩洛哥)油页岩的这种矿物基质进行加氢处理时,硫化镍作为添加剂的影响。本研究采用的技术包括热重仪(Red-Croft)、热量计(DCE)、X 射线衍射和扫描电子显微镜下的色散 X 射线衍射。在硫化镍添加过程中观察到了碳酸盐分解活动,阻止了 NiSO4, 6H2O 在氢气存在下的原位分解,提高了方解石、白云石、高岭石和石英的转化率。
