Biomass autothermal reforming

CO = 25 vol.%, C02 = 12 vol.%) not containing any hydrocarbons and a low tar (200 mg Nm 3) content at 800 °C and S/C (steam over carbon ratio) = 1.5. Problems associated with pyrolysis oil gasification are similar to those of biomass gasification. Gasification of the tar fraction and conversion of methane formed are important challenges. Both require highly active and stable steam/autothermal reforming catalysts. 

Since most biomass compositions are hydrocarbons or oxidative hydrocarbon with a general molecular formula of CnlT,nOz [25], biomass processing can use similar technologies for the hydrogen production via natural gas. The reactions of steam reforming of biomass, biomass partial oxidation, and biomass autothermal reforming are summarized in Table 9.5 [25].

Liquefaction of biomass is mostly performed at low temperature and high pressure in presence of hydrogen and a catalyst. The process results in a liquid product along with considerable amount of tars which makes the process expensive for their removal. Autothermal reforming is an attractive alternative...
