Natural refrigerants are preferred actually in new equipment to their synthetic counterparts for their presumption of higher degrees of sustainability. With the current technologies available, almost 75 percent of the refrigeration and air conditioning sector has the potential to be converted to natural refrigerants. [2]
Methanol is a fuel for heat engines and fuel cells. Due to its high octane rating it can be used directly as a fuel in flex-fuel cars (including hybrid and plug-in hybrid vehicles) using existing internal combustion engines (ICE). Methanol can also be burned in some other kinds of engine or to provide heat as other liquid fuels are used.
Methanol Synthesis: Syngas is fed to Reactor 1, the first of four reactors, which converts most of the syngas to methanol when passing through the catalyst bed. CO + 2 H 2 → methanol CH 3 OH Dimethyl Ether (DME) Synthesis: The methanol-rich gas from Reactor 1 is next fed to Reactor 2, the second STG+ reactor.
In future designs, [11] [12] the oxygen by-product may be combined with renewable natural gas in the oxidative coupling of methane to ethylene: [13] [14] 2 CH 4 + O 2 → C 2 H 4 + 2 H 2 O. The reaction is exothermic (∆H = -280 kJ/mol) and occurs at high temperatures (750–950 ˚C). [15]
The carbon dioxide used to make synthetic fuels may be directly captured from the air, recycled from power plant flue exhaust gas or derived from carbonic acid in seawater. Common examples of synthetic fuels include ammonia and methane , [ 2 ] although more complex hydrocarbons such as gasoline and jet fuel [ 3 ] have also been successfully ...

In the direct air capture process, ambient air is sucked in and transferred to a sorbent, in which the carbon dioxide forms a chemical bond with an absorbent or adsorbent, separating it from the air. Subsequently, during regeneration of the sorbent, or desorption, the carbon dioxide is separated by the addition of thermal energy and prepared ...
Methanol is an industrial chemical found in antifreeze and windshield washer fluid. It's not meant for human consumption and is highly toxic. Drinking even small amounts can be damaging.
