| Abstract |
A two-step process for the complete gasification of aqueous carbohydrate streams towards H-2 and CH4 production is proposed. Sucrose is selected as a model compound that represents aqueous carbohydrates in waste water streams. In the first step, called stabilisation, sucrose is treated with H-2 under mild temperatures and is fully converted to sorbitol and mannitol using 5wt% Ru/C as a hydrogenation catalyst. In the second step, the stabilised mixture is gasified at 300 degrees C using 5wt% Pt-Al2O3 and 5wt% Ru-C. A combination of the two catalysts in series provides enhanced gasification without compromising on the H-2 yield. This process provides an opportunity to obtain clean water and valuable fuels (H-2 and CH4) from low-value carbohydrate or wastewater streams that otherwise would typically present coking problems upon gasification. The presence of an additional stabilisation step enhances gasification with no additional requirement of H-2. |
