What is Gasification?
A Business Unit of GBH Enterprises, Ltd.
Gasification converts any carbon-containing material into
synthesis gas, composed primarily of carbon monoxide and
hydrogen (referred to as syngas)
Syngas can be used as a fuel to generate electricity or steam,
as a basic chemical building block for a large number of uses
in the petrochemical and refining industries, and for the
production of hydrogen
Gasification adds value to low- or negative-value feedstocks
by converting them to marketable fuels and products

Gasification – Differences from Combustion
Add water and high pressure
Use less air or oxygen
Gasification exit gases are at high pressure, so smaller
volume, smaller reactors
Combustion makes heat + CO2 + H2O
Gasification makes less heat + carbon monoxide + hydrogen
(CO + H2); called Syngas

So what can you do with CO and H2 ?

Water-Gas-Shift (WGS) Reaction
Dry syngas is ~ 40% CO + 50% H2
For each CO molecule the WGS reaction creates one H2 molecule
and one CO2 molecule
CO + H2O + catalyst CO2 + H2
After the WGS reaction, the CO2 and H2 can be separated
High pressure CO2 results in lower cost sequestration
Hydrogen can be burned to make power
2H2 + O2 2H2O

Benefits of Gasification
Feedstock flexibility
Wide range of coals, petcoke, liquids, wastes, biomass can be utilized
Product flexibility
Syngas can be converted to high valued products: electricity, steam,
hydrogen, liquid transportation fuels, chemicals, SNG
Environmental superiority
Pollutants can be economically controlled to extremely low levels (SO2,
NOX, CO, Hg, etc.)
Reduced water consumption
Potential solid wastes can be utilized or easily managed
High efficiency / low CO2 production
CO2 can be easily captured for sale or geologic storage (sequestration)
