Journal ArticleDOI
An experimental study on biomass air-steam gasification in a fluidized bed.
TL;DR: The results showed that higher temperature contributed to more hydrogen production, but too high a temperature lowered gas heating value, and a smaller particle was more favorable for higher gas LHV and yield.

Selection of Oxygen Carriers for Chemical-Looping Combustion
Juan Adánez,L.F. de Diego,Francisco García-Labiano,and Pilar Gayán,Alberto Abad,J.M. Palacios +5 more
TL;DR: In this paper, the authors used a metal oxide as an oxygen source, and an inert as a binder for increasing the mechanical strength of the carrier, which is used to transfer oxygen from the air to the fuel, preventing direct contact between them.
