Effect of additives on dolomite-supported Ni catalysts for coal tar cracking

Promoting dry reforming of methane via bifunctional NiO/dolomite catalysts for production of hydrogen-rich syngas

“…It was conrmed that Ni and dolomite formed a stable phase of MgNiO 2 , which increased the degree of Ni distribution and hindered Ni agglomeration in the DRM process. 19 As proved by Table 2. NiO crystallite size increased as the following order: 5% NiO/dolomite > 15% NiO/dolomite > 10% NiO/dolomite.…”

“…It was confirmed that Ni and dolomite formed a stable phase of MgNiO 2 , which increased the degree of Ni distribution and hindered Ni agglomeration in the DRM process. 19 …”

“…Noteworthy, the synergetic effect between NiO and dolomite have been proven to hinder coke formation. Although NiO supported on dolomite (NiO/dolomite) was reported to have outstanding catalytic performance in a variety of reaction process such as oil cracking, 19 pyrolysis/reforming, 20 steam reforming, 21 and gasification. 22 However, there is no evidence in the previous literature of NiO/dolomite being used as a catalyst in the DRM reaction.…”
