The materials produced with a low superheat exhibit a fine globular structure.
The results show that the tendencies of true stress-true strain responses for all materials were similar except for the materials poured at high temperature with very large dendrtic structure having a higher peak stress.
Materials were cast at 725,650 and 625oC,respectively.

In a dual fluidized bed reactor, char produced in the gasifier and materials recycled into the combustion chamber.The heat released from char combustion is transported by the circulating material into the gasifier for endothermic steam gasification reactions[6].
Because of the use of CaO , circulating bed material becomes not only heat carrier to provide heat for the steam gasification, but also CO2 acceptor and carrier.
Environment temperature 20℃, Initial bed material is CaO with amount of 100kg.The composition of straw is shown in Table 1.
