GAS-L: Syngas genset

[Peter Singfield <snkm@btl.net>]

Hi Ariel;

I have reformatted your chart by "guess" -- could you verify if this is
correct?

One question -- your gas products appear to be the result of steam
reformations under 3 differing conditions. Probably just temperature?
Methane being the product of steam reformation at lower temperatures.

What process are you using and with what carbon material as charge?

Could you enlighten us please?

Hello,

I have noticed the syngas composition did not go through so I am re-sending
my inquiry:

I am running an experiment of producing syngas (Gas rich with Hydrogen) and
feeding it to a reciprocating gas engine, the composition of the syngas
varies according to the process temperature from syngas I to syngas III as
follows:. 
   
Composition [moll - %]            
Gas                                                     Syngas I
Syngas II        Syngas III

Methane                                               0.296037
0.14331           0.020385
Carbon Monoxide                                  0.038796         0.100443
0.189042
Carbon Dioxide                                     0.185704         0.14857
0.088326  
Hydrogen                                             0.477759
0.607774          0.702234

Density                                                    6.22
5.35                  4.54
Net heating value (60 Deg. F) [kj/kg]          24353             22592
21968
Vol. LHV [kj/m^3]                                   151398            120783
99694

The gas conditions are at 25 Deg. C and 10 bar

The gas can be supplied at 10-50 Deg. C and at constant pressure in the
range of 10-15 barg to the engine.
If needed it is also possible to start the engine with liquid fuel or LPG
and then change over to the syngas.

The area the engine will be placed is classified as Class 1 Div.2 Group B
because of the Hydrogen presence.
The electrical output of the engine should be in the range of 100-400
kWe.(No heat recovery needed)

Can anyone direct me to a company that could supply a gas engine that could
stand in this specifications?
