Abstract

Improving the productivity of gasification process and its syngas product utility value has been carried out by applying the dolomite catalyst method. This research has been tested on pilot scale which is manufactured and installed based on the updraft gasification technology principle. Dolomite catalyst is mixed with rice husk. Research results showed that with 15 % w dolomite catalyst used and gasificated by is air with 3 m3/h flow, the gasification producvity is improved up to 23.45 % comprared with the case of without catalyst (7.76 %). The syngas productivity and its energy value is 67% and 3.36 MJ/Kg, respectively. The ratio of H2 and CO of syngas product is also improved. The syngas product is similar to syngas standard which could be directly used for gaz generator.
