Synthesis gas conversion into hydrocarbons (gasoline range) over bifunctional zeolite-containing catalyst: experimental study and mathematical modelling

Synthesis of gasoline-range hydrocarbons from nitrogen-rich syngas over a Mo/HZSM-5 bi-functional catalyst

“…MTG selectively converts methanol to liquid product: a very low sulfur, low benzene regular octane gasoline, which can be a valuable blending component for meeting environmental regulations specific to sulfur and benzene [19]. Simultaneous synthesis of methanol from syngas (over the metallic function) and transformation of methanol into hydrocarbons (over the acidic function) can also be done with bifunctional catalysts.…”

“…An alternative commercially proven route for converting syngas to liquid fuels is through the conversion of methanol to gasoline (MTG) [19]. MTG selectively converts methanol to liquid product: a very low sulfur, low benzene regular octane gasoline, which can be a valuable blending component for meeting environmental regulations specific to sulfur and benzene [19].…”

“…Methanol is first dehydrated to dimethyl ether (DME). Then an equilibrium mixture of methanol, DME and water is converted to light olefins (C 2 eC 4 ) [19]. A final reaction step leads to the synthesis of higher olefins, n/iso-paraffins, aromatics and naphthenes.…”

“…A mechanism by which a bi-functional catalyst works is described in Eqs. (3)e(6) [19]. Methanol is first dehydrated to dimethyl ether (DME).…”

Techno-economic analysis of a process for CO2-free coproduction of iron and hydrocarbon chemical products

“…Efforts to use light alkanes to produce olefins and aromatics by selective partial oxidation and oxidative coupling of methane (OCM) using limited oxygen have been ongoing [18]. These catalytic processes have been identified as providing the largest potential for greenhouse gas emissions reductions in the IEA chemical industry roadmaps [2].…”
