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

Extensive effort has been focused on the advancement of an efficient catalyst for CO reforming of CH to achieve optimum catalytic activity together with cost-effectiveness and high resistance to catalyst deactivation. In this study, for the first time, a new catalytic support/catalyst system of bifunctional NiO/dolomite has been synthesized by a wet impregnation method using low-cost materials, and it shows unique performance in terms of amphoteric sites and self-reduction properties. The catalysts were loaded into a continuous micro-reactor equipped with an online GC-TCD system.

Development of bimetallic nickel-based catalysts supported on activated carbon for green fuel production.

In this work, the catalytic deoxygenation of waste cooking oil (WCO) over acid-base bifunctional catalysts (NiLa, NiCe, NiFe, NiMn, NiZn, and NiW) supported on activated carbon (AC) was investigated. A high hydrocarbon yield above 60% with lower oxygenated species was found in the liquid product, with the product being selective toward -(C + C)-diesel fractions. The predominance of -(C + C) hydrocarbons with the concurrent production of CO and CO, indicated that the deoxygenation pathway proceeded decarbonylation and decarboxylation mechanisms.
