Beyond hydrogen: Process design of a biogas steam reformer for Fischer–Tropsch synthesis

The Canadian Journal of Chemical Engineering, EarlyView.
The effect of pressure and steam to carbon ratio on carbon conversion. Abstract We present an analysis of a pilot‐scale multi‐tubular biogas steam reforming reactor, part of a sustainable aviation fuel (SAF) development project in Brazil. The novelty of this work is the application of a new, validated power law kinetic model, specifically developed for

Rational design of Ni‐based catalysts for methane dry reforming: Recent advances and future perspectives

FlexMat, EarlyView.
Addressing the challenges inherent in dry reforming of methane (DRM), this paper focuses on the structural design and performance optimization of Ni‐based catalysts. The modulation strategies for DRM are systematically reviewed across four dimensions: the micromorphology of active metals, metal‐support interactions, electronic modifications by ...

ПРОЦЕССЫ ВО ВРЕМЯ ОТЖИГА КОНТАКТНЫХ СИСТЕМ Ti—Al—Ni И Ti—Al—Ni—Au

, 2015
The Ti/Al/Ni/Au metallization system which is widely used in the technology of GaN based devices has a very important disadvantage: after annealing in nitrogen atmosphere for 30 sec. at temperature 850 оС it has rough surface with 300 nm hillocks.

Synthesis and oxidation behavior of Al@Ni-Fe core-shell energetic composite powders

Energetic Materials Frontiers
In this study nickel (Ni) and iron (Fe) co-deposition was performed on Al to produce Al@Ni-Fe core-shell energetic powders using electroless deposition. Energy released from Al@Ni-Fe powders in oxidizing environment was investigated to characterize their

Dry Reforming of Biogas Over Li–Ni–Al Catalysts: Influence of Li Incorporation Method

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Hydrogen is a promising source of energy, given the current context of depletion of fossil fuels and increased emissions of greenhouse gases. The technological route for obtaining this fuel from the dry reforming of biogas has received considerable attention from researchers, as it converts the polluting gases CH4 and CO2 into synthesis gas ...
