P-10　Steam gasification of rice husk in the presence of calcined seashells

Abstract

Rice husk (RH) contains a high content of silica (Si), and it is not so easy to be gasified at a low gasification temperature. To enhance hydrogen yield from the gasification of rice husk, the disposal seashells obtained from sea bay of Aomori prefecture, Japan, was calcinated at 900°C, and utilized as the catalyst. The effects of reaction temp erature and steam flow rate on the gasification of RH in the presence of different amounts of calcined seashells (CS) were investigated in details. It is found that the addition of CS can effectively enhance the gasification of CS at low temperatures
