February 2, DOI: Thus, an efficient one-pot hydrogen carrier system has been developed. It acts as a clean source of hydrogen without concurrent production of CO2 unlike steam reforming or CO by complete methanol dehydrogenation. Therefore, a carbon neutral cycle is essentially achieved where no carbon capture is necessary as the carbon is trapped in the form of formamide or urea in the case of primary amine.

In theory, a hydrogen storage capacity as high as 6. May 25, DOI: Only given sufficient geological time, millions of years, can new fossil fuels be formed naturally.

To supplement the natural carbon cycle, we have proposed and developed a feasible anthropogenic chemical recycling of carbon dioxide. Carbon dioxide is captured by absorption technologies from any natural or industrial source, from human activities, or even from the air itself.

It can then be converted by feasible chemical transformations into fuels such as methanol, dimethyl ether, and varied products including synthetic hydrocarbons 160517 essay even proteins for animal feed, thus supplementing our food chain. This concept of broad scope and framework is the basis of what we call the Methanol Economy.

Ar and Why Its Important - Sample Essays

The needed renewable starting materials, water and CO2, are available anywhere on Earth. The required energy for the synthetic carbon cycle can come from any alternative energy source such as solar, wind, geothermal, and even hopefully safe nuclear energy.

The anthropogenic carbon dioxide 160517 essay offers a way of assuring a sustainable future for humankind when fossil fuels become scarce. While biosources can play a limited role in supplementing future energy needs, they increasingly interfere with the essentials of the food chain.

We have previously reviewed aspects of the chemical recycling of carbon dioxide to methanol and dimethyl ether.

In the present Perspective, we extend the discussion of the innovative and feasible anthropogenic carbon cycle, which can be the basis of progressively liberating humankind from its dependence on diminishing fossil fuel reserves while also controlling harmful CO2 emissions to the atmosphere.

We also discuss in more detail the essential stages and the significant aspects of carbon capture and subsequent recycling. April 5, DOI: Their formation pathways, their related extraterrestrial hydrocarbon chemistry originating from carbon and other elements after the Big Bang, their parent hydrocarbon and derivative methane and methanol, respectivelyand transportation of derived building blocks of life by meteorites or comets to planet Earth are discussed in this Perspective.

The relevance and significance of extraterrestrial hydrocarbon chemistry to the limits of science in relation to the physical aspects of evolution on our planet Earth are also discussed. Olah; Thomas Mathew; G. January 13, DOI: Feasible pathways and chemical aspects of their formation as well as of derived hydrocarbon homologues and their ions carbocations and carbanions are discussed on the basis of observed similarities with our studied terrestrial chemistry.

The preferred pathway for converting extraterrestrial methane according to Ali et al. On the basis of the observed higher reactivity of methanol compared with methane in various chemical reactions, a feasible new pathway is proposed for the conversion of extraterrestrial methanol to hydrocarbons, their derivatives, and carbocations together with a possible connection with methonium ion-based chemistry.

December 16, DOI: Alternate panspermia of similar extraterrestrially formed and observed hydrocarbons to earth is also discussed. September 27, DOI: Being a solid substance, the catalyst can be recovered by a simple filtration, if necessary.

Furthermore, addition of neat formic acid is sufficient to reuse the catalyst and maintain a constant flow of H2 and CO2 mixture and the stable performance of a coupled fuel cell. The easy to recycle catalyst did not show any loss of activity after 20 days of continuous use, and similar activity was observed even a year after the original preparation.

This integrated system embodies the first example of an indirect formic acid fuel cell, which can function, without the requirement of applying inert conditions and feed gas purification, for extended periods of time. December 29, DOI: Ease of separation of CH3OH is demonstrated by simple distillation from the reaction mixture.

Various sources of CO2 can be used for this reaction including air, despite its low CO2 concentration ppm. June 18, DOI: Hang Zhang, Alain Goeppert, G. The stability of the adsorbents under CO2, air, and N2 was also investigated. Surya Prakash and George A.An Easy Essay.
