“…13 Direct CH 4 conversion to liquids via one step process has been sought for decades, yet challenges persist. These methods can be divided into two broad groups: 14,15 1. Direct endothermic dehydrogenation of CH 4 to −CH 2 − containing species and H 2 at high temperatures (500− 1100°C).…”

Carbon dioxide is a greenhouse gas and is obtained as a waste via burning various forms of fuels. Syngas is an intermediate in large-scale long-chain hydrocarbon (C 10 − C 20 alkanes and alcohols) production processes via Fischer− Tropsch (FT) synthesis, typically to obtain high quality fuels. Thus, it is of particular interest to engineer syngas production processes for FT that can consume various combustion process waste CO 2 in the process and thus partially contribute to the sustainable carbon neutral fuel synthesis. In this work, a quantitative economic comparison of five alternative processes is presented for the production of synthesis gas with a hydrogento-carbon monoxide ratio of 2, which is suitable for feeding to the Fischer−Tropsch gas-to-liquid process. Combinations of steam methane reforming (SMR), dry methane reforming (DMR), autothermal reforming (ATR) and reverse water gas shift (RWGS) are explored. An amine absorber/stripper system is used for carbon dioxide removal. The effects of the cost of natural gas and of liquid oxygen and the magnitude of a potential carbon tax are demonstrated. With current prices of raw materials, the configuration with the lowest total annual cost (TAC) features a system composed of both SMR and DMR reactors.

“…Production of value added chemicals and fuels, such as olefins (ethene, propene), benzene derivatives (benzene, toluene, xylene-BTX), and C 5+ liquid fuels is of major industrial importance. When natural gas is used as a raw material, syngas (CO + H 2 ) or methanol (CH 3 OH) routes are typically used [1][2][3]. CH 3 OH is a convenient platform molecule [4,5] to obtain higher hydrocarbons since it is liquid in ambient conditions and reacts via well-defined and explored catalytic pathways, thus allowing for a high desired product selectivity [6,7].…”

Methyl mercaptan, CH 3 SH, is an industrial waste as well as the reactive product of several H 2 and H 2 S induced catalytic hydrogenation processes of COS and CS 2. Its coupling into value added products is of great importance in monetizing sour natural gas. In the present work, the full theoretical cycle of catalytic CH 3 SH coupling to form ethene was investigated by means of density functional theory (DFT) using chabazite as a model catalyst with emphasis on the first C C bond formation. Calculated thermodynamics were compared with those of analogous and well established CH 3 OH processes to identify the similarities and differences in the reactive pathways. With few exceptions, CH 3 SH catalytic transformations are of higher free energy when compared to those of CH 3 OH. The trimethylsulfonium ion, TMS, isostructural with that of the trimethyloxonium ion, TMO, is shown to be a key reactive intermediate and a thermodynamically stable species leading to ethene formation.

“…Fuels cells have emerged as a promising technology due to its high energy conversion efficiency, low pollution and excellent fuel flexibility [2,3]. For example, the solid-oxide fuel cells (SOFCs) enable the direct electrochemical conversion of hydrocarbons fuels by internal steam reforming of methane (CH 4 ) [4,5]. Despite the high chemical activity and excellent thermal of Ni catalyst is a preferred anode material [6], but some fatal issues are still presented as the hydrocarbon fuels are used.…”
