Modeling study on the production of hydrogen/ syngas via partial oxidation using a homogeneous charge compression ignition engine fueled with natural gas

Morsy, Mohamed H. . 2014

The production of hydrogen and syngas from natural gas using a homogeneous charge
compression ignition reforming engine is investigated numerically. The simulation tool
used was CHEMKIN 3.7, using the GRI-3 natural gas combustion mechanism. This simulation
was conducted on the changes in hydrogen and syngas concentration according to
the variations of equivalence ratio, intake temperature, oxygen enrichment, engine speed,
initial pressure, and fuel additives with partial oxidation combustion. The simulation results
indicate that the hydrogen/syngas yields are strongly dependent on the equivalence
ratio with maxima occurring at an optimal equivalence ratio varying with engine speed.
The hydrogen/syngas yields increase with increasing intake temperature and oxygen
contents in air. The hydrogen/syngas yields also increase with increasing initial pressure,
especially at lower temperatures, yet high temperature can suppress the pressure effect.
Furthermore, it was found that the hydrogen/syngas yields increase when using fuel additives,
especially hydrogen peroxide. Through the parametric screening studies, optimum
operating conditions for natural gas partial oxidation reforming are recommended at 3.0
equivalence ratio, 530 K intake temperature, 0.3 oxygen enrichment, 500 rpm engine speed,
1 atm initial pressure, and 7.5% hydrogen peroxide.
