Steam Reforming and Oxidative Steam Reforming of Isobutanol Over Supported Metal Catalysts.
PhD thesis, Indian Institute of Technology Hyderabad.
Abstract
The human civilization is deeply reliant on fossil fuels to meet societal needs of
energy and organic chemicals. The fossil fuels reserves are however diminishing
continuously to meet growing demands of energy and organic chemicals of the
world’s mounting population with improved standards of living. The increased
usages of fossil fuels have also vast impact on earth environment due to emissions
of greenhouse gases (CO2 and CH4) which are responsible for global warming.
Therefore, there is a strong need of finding carbon-neutral renewable resources for
sustainable production of energy and organic chemicals while preserving earth
environment. In recent times, the bio-n-butanol has been received widespread
attention as bio-fuel because of its superior fuel qualities over biodiesel and bioethanol.
The isobutanol having lesser toxicity and higher octane number compared
to n-butanol and same essential fuel potentials as n-butanol is deliberated as one of
the promising bio-fuels of the future. Once bio-butanols based biorefinery is
realized successfully, novel methods of production of synthesis gas (SG) must also
be established from bio-butanols. Apprehending tremendous upcoming prospective
of bio-butanols based biorefinery, present work initiated to explore experimental
and thermodynamic investigation on steam reforming (SR) and oxidative steam
reforming (OSR) of isobutanol over supported metal catalysts for production of SG.
The SG finds wide ranges of applications in chemical industries, for example,
manufacture of hydrogen, ammonia, fertilizers, methanol, and dimethyl ether by
Fischer-Tropsch synthesis (FTS). SG also provides a source of highly pure
hydrogen for fuel cell applications to generate electric power in an environmentally
cleaner manner.
