I must write a brief explanation about biomass and coal gasification. I am confused when I must explain hydrogen production from gasification. I can understand quite well about biomass gasification, because biomass contains H in their chains. But I still have no idea when many authors wrote about producing Hydrogen from coal.<BR>
<BR>
AFAIK coal is mainly carbon, but many wrote this reaction, concerning</FONT><FONT COLOR="#000000" FACE="Geneva" FAMILY="SANSSERIF" SIZE="2"><B> oxygen gasification</B></FONT><FONT COLOR="#000000" FACE="Geneva" FAMILY="SANSSERIF" SIZE="2"><BR>

C + O2 --> CO2<BR>
C + 1/2 O2 --> CO<BR>
H + 1/2 O2 --> H2O<BR>
<BR>
my question is where does the</FONT><FONT COLOR="#000000" FACE="Geneva" FAMILY="SANSSERIF" SIZE="2"><B> hydrogen</B></FONT><FONT COLOR="#000000" FACE="Geneva" FAMILY="SANSSERIF" SIZE="2"> in that reaction come from if it is not a steam gasification?<BR>
Or it should be a steam gasification ?<BR>
<BR>
Thank you,<BR>
