Abstract:
The H2020 Pulp&Fuel project intends to make a significant contribution to biofuel development by taking advantage of the synergy between dry gasification and supercritical water gasification. The project has chosen to demonstrate its applicability to pulp industry that have both dry and wet wastes available. The process produces sludge as wet waste and an excess of black liquor in chemical pulp mills. Supercritical water gasification (SCWG) is considered the most suitable route as no drying step is required to transform wet waste as black liquor in syngas (mainly composed of H2, CH4 and CO2). The objective is to maximize organic matter conversion of black liquor into a gas and to maximize H2 yield production. Black liquor gasification is studied in two kinds of reactors in the CEA platform: batch and continuous reactor. This paper focuses on batch experiments. Some batch experiments (55 runs) have been performed to characterize gasification efficiency, gas composition and carbon conversion in liquid, solid, and gaseous phase.
