Abstract


This research studied  the  fluizided bed gasification  process of wood  waste that could produce  highly yield  and good quality   of fuel gas.

The processing  treatments  were conducted at 3 levels of  wood  feed flow  rate i.e 3. 6., 3.8 and 4.2  kgs/hour and 5 leveis  of air flow rate i.e  4.4,  4.7, 5.0,5.4 and 6.5  m3/hour.

The  result  revaled that highest  caloriffic  value of produced gas was 7.106  MJ/m3   which  resulted  from  wood  feed and air  flow  rate  3. 6 kg/hour  and  4. 4  m3 /hour, respectively.  The product   gas composition  of  this  rate  was H2  = 5. 62 .CH = 3.99; CO=  11.77; C2H4 = 4.34;  C2H6 = 0.21; N2 = 57.69; 02 = 0.40 and C02 = 15. 71 (in  %  volume)

The highest  total  energy  of product   gas was 20.36  MJ/m3  with fuel gas efficiency 26.16% which  resulted  from  feed and  air flow rote  4.2 kg/hour  and  6.5  m3/hour, respectively.  The product   gas composition at this rate  was H2  = 6.03; CH4  = 3.51;  CO=  12.60;  C2H4  = 2.46; C2H6  = 0.16; N2  = 57.23;  02  = 0.45  and C02   = 17.58,  while  the fluidued   bed gasification process  was held at 97oᵒC.
