The Covid era has made us aware of the need for resilient, self-sufficient, and local production. We are likely willing to pay an extra price that quality. Ammonia (NH3) synthesis accounts 2 % global energy production is important point attention development green technologies. Therefore, we propose a thermally integrated process H2 NH3 using plasma technology, evaluate its techno-economic perf...

Oxidative coupling of methane (OCM) is a promising method for the direct conversion of methane to ethene and ethane (C2 products). Among the catalysts reported previously, Mn2O3-Na2WO4/SiO2 showed the highest conversion and selectivity, but only at 800° to 900°C, which represents a substantial challenge for commercialization. We report a TiO2-doped Mn2O3-Na2WO4/SiO2 catalyst by using Ti-MWW zeo...

In this paper, the effect of hydrogen addition on methane coupling in a microwave moderate pressure (55 mbar and 110 mbar) plasma reactor has been studied. The use optical emission spectroscopy allowed determination rotational temperature heavy particles showed it to be range 3000–4000 K. Due high discharge dominant product was acetylene concluded that process is mainly through thermal decompos...

Ultra-thin, high performance composite palladium membrane, developed via a novel electroless plating method, was applied to construct a membrane reactor for methane steam reforming reaction, which was investigated under the following working conditions: temperature 723–823 K, pressure 300–900 kPa, gas hourly space velocity (GHSV) 4000–8000 mL g 1 cat h , steam-to-carbon feed ratio (S/C, mol/mol...

Partial oxidation of methane in monolithic catalysts at very short contact times has recently been shown to offer a promising route to convert natural gas into syngas (CO, H2), which can subsequently be converted to higher alkanes or methanol. Detailed models are needed to understand the complex interaction of transport and kinetics occurring in these reactors. In this work, the partial oxidati...

Developing efficient catalytic processes to convert methane into useful feedstocks relies critically upon devising new coupling processes that use abundant, thermodynamically 'mild' oxidants together with selective catalysts. We report here on elemental sulfur as a promising 'soft' oxidant for selective methane conversion to ethylene over MoS(2), RuS(2), TiS(2), PdS and Pd/ZrO(2) catalysts. Exp...

Introduction Research on the conversion of natural gas (methane) has been an ongoing effort at the National Energy Technology Laboratory (NETL) for over 20 years. A long-term goal of our research team is to explore novel pathways for the direct conversion of methane to liquid fuels, chemicals, and intermediates. Scheme 1: Proposed pathway for the photocatalytic conversion of methane and water L...
