Considering the future demand gor hydrogen, advanced coal gasification technology is a promising alternative. In the present study, the screening of catalysts for coal char-steam gasification, and gasification tests using fluidized beds were carried out which successfully applied fluidized bed technology to catalytic coal gasification. Catalyst screening was carried out by using a TG type apparatus on the following groups of catalysts: (I) chlorides, carbonates, hydroxides, nitrates, and sulfates of alkali metals, (II) chlorides, nitrates, and sulfates of alkaline earth metals, and (III) chlorides, nitrates, and sulfates of transition metals. Two kinds of coals, Mettiki (USA) and Womboo (Australia), were mainly used in the form of catalyst-supported char (1.0meq-metal/g-char). The gasification temperature was 1098 K and the partial pressure of steam was 12.2 kPa. The result of the screening showed that K_2CO_3-Mettiki char system was the most favorable one for hydrogen production. The effects of the catalyst loading and the partial pressure of steam on the gasification rate were investigated for the system. Mettiki char with a catalyst (K_2CO_3 or Na_2CO_3) was gasified by steam in fluidized beds (10 cm and 15 cm of internal diameter) at 1098 K. The gasification experiments in fluidized beds showed that the quartz sand used as ballast acted as an inhibitor to the gasification. By using ceramic particles supporting Li_2CO_3, the inhibition effect decreased. |
