PRODUCTION OF HYDROCARBONS FROM CARBON DIOXIDE AND WATER

Abstract
To improve the sustainability of transportation, a major goal is the replacement of conventional petroleum-based fuels with more sustainable fuels that can be used in the existing infrastructure (fuel distribution and vehicles). While fossil-derived synthetic fuels (e.g. coal derived liquid fuels) and biofuels have received the most attention, similar hydrocarbons can be produced without using fossil fuels or biomass. Using renewable and/or nuclear energy, carbon dioxide and water can be recycled into liquid hydrocarbon fuels in non-biological processes which remove oxygen from CO2 and H2O (the reverse of fuel combustion). Capture of CO2 from the atmosphere would enable a closed-loop carbon-neutral fuel cycle.

This article critically reviews the many possible technological pathways for recycling CO2 into fuels using renewable or nuclear energy, considering three stages—CO2 capture, H2O and CO2 dissociation, and fuel synthesis. Dissociation methods include thermolysis, thermochemical cycles, electrolysis, and photoelectrolysis of CO2 and/or H2O. High temperature co-electrolysis of H2O and CO2 makes very efficient use of electricity and heat (near-100% electricity-to-syngas efficiency), provides high reaction rates, and directly produces syngas (CO/H2 mixture) for use in conventional catalytic fuel synthesis reactors. Capturing CO2 from the atmosphere using a solid sorbent, electrolyzing H2O and CO2 in solid oxide electrolysis cells to yield syngas, and converting the syngas to gasoline or diesel by Fischer–Tropsch synthesis is identified as one of the most promising, feasible routes.

An analysis of the energy balance and economics of this CO2 recycling process is presented. We estimate that the full system can feasibly operate at 70% electricity-to-liquid fuel efficiency (higher heating value basis) and the price of electricity needed to produce synthetic gasoline at U.S.D$ 2/gal ($ 0.53/L) is 2–3 U.S. cents/kWh. For $ 3/gal ($ 0.78/L) gasoline, electricity at 4–5 cents/kWh is needed. In some regions that have inexpensive renewable electricity, such as Iceland, fuel production may already be economical. The dominant costs of the process are the electricity cost and the capital cost of the electrolyzer, and this capital cost is significantly increased when operating intermittently (on renewable power sources such as solar and wind). The potential of this CO2 recycling process is assessed, in terms of what technological progress is needed to achieve large-scale, economically competitive production of sustainable fuels by this method.

wen pa kaha ni mabuhat..? if wa na c mother earth?..

[james_uy44]

let's call on our world class chemists and chemical engineers na buhaton ni dni sa Pilipinas... ato ipa sponsor ni Madame Janet "baboy" Napoles...

[EkOng]

Lisod-Lisod ni BoSs..!Ang process..

but adunay maka buhat ani pero need funds,.

maka buhat man gani but not in the exactly 100% good kay sa mga materials og apparatus lng ta patyon.

upppppppppppp

[*sludge*]

OT: misleading man ang title bradier.. kay basing sa title abi nko naa nay na nahimo ani..

[stan_the_man21ph]

Ayaw ihatag sa DOST ang budget kay apil diay sa pdaf scam bantog ra wala kaayo naimbento diri pinas kay ang para ta sa mga scientist kay para man diay sa mga scientists sa pagpangawkaw...

d malipay ang mga oil companies ani. . i suppress jud ni xa kung mahitabo man gani. .
