“…These results demonstrate for the first time experimentally that the use of membrane reactors with a distributed H 2 feed via Pd/Ag membranes can increase the production of the desired fraction of high molecular weight hydrocarbons provided that suitable FTS reaction conditions are identified. In addition, the results obtained confirm the predictions of recent models developed to study the use of different configurations of membrane reactors for FTS which predict the formation of a higher yield to heavier hydrocarbons fraction [16][17][18].…”

“…More recently, Ghareghashi et al [17] reported a simulation of the use of two consecutive reactors: a catalytic fixed bed reactor for the oxidative coupling of methane (OCM) and a fixed bed membrane FTS reactor using a Pd/Ag based H 2 perm-selective membrane and an Fe-based catalyst. The study concluded that the concept of a membrane FTS reactor together with OCM feed is an interesting method for increasing C 5+ and decreasing undesired products such as CO 2 and methane.…”

Direct Conversion of Methane to C₂Hydrocarbons in Solid-State Membrane Reactors at High Temperatures

et al. 2021

Direct conversion of methane to C2 compounds by oxidative and nonoxidative coupling reactions has been intensively studied in the past four decades; however, because these reactions have intrinsic severe thermodynamic constraints, they have not become viable industrially. Recently, with the increasing availability of inexpensive “green electrons” coming from renewable sources, electrochemical technologies are gaining momentum for reactions that have been challenging for more conventional catalysis. Using solid-state membranes to control the reacting species and separate products in a single step is a crucial advantage. Devices using ionic or mixed ionic–electronic conductors can be explored for methane coupling reactions with great potential to increase selectivity. Although these technologies are still in the early scaling stages, they offer a sustainable path for the utilization of methane and benefit from the advances in both solid oxide fuel cells and electrolyzers. This review identifies promising developments for solid-state methane conversion reactors by assessing multifunctional layers with microstructural control; combining solid electrolytes (proton and oxygen ion conductors) with active and selective electrodes/catalysts; applying more efficient reactor designs; understanding the reaction/degradation mechanisms; defining standards for performance evaluation; and carrying techno-economic analysis.

“…[1,2] In particular, CH 4 is commercially viable, because it can be synthesized industrially through various processes. [3][4][5] Gas-to-liquid (GTL) process has received significant attention as a promising technology. This technology mainly comprises three processes: reforming of natural gas, Fischer-Tropsch (FT) synthesis, and upgrading.…”

Plasma methane activation on mesoporous silica for energy efficiency improvement

This study describes plasma CH4 activation on mesoporous silica (SBA‐15) with a high specific surface area (SSA) for energy efficiency improvement. A dielectric barrier discharge plasma was used, and the SSA of SBA‐15 was varied by controlling the hydrothermal reaction (HR) temperature. The effect of the SSA was investigated to improve the plasma CH4 activation. The synthesized SBA‐15 had a well‐ordered two‐dimensional hexagonal structure. CH4 conversion and C2 selectivity using plasma catalysis were twice as high as those using only the catalyst, because vibrationally excited CH4 can be adsorbed with low activation energy. Additionally, the energy efficiency was higher than that of other plasma catalysts when the plasma was applied to mesoporous SBA‐15 with the SSA of 516 m2 g−1 at a discharge frequency of 0.1 kHz.
