Abstract:

Supercritical water coal steaming technology has outstanding advantages such as fast reaction speed, high hydrogen production, no emission of gaseous pollutants, low water consumption and strong material adaptability. At the sub-particle scale, the micro-scale momentum and energy transfer mechanism of the particle-supercritical water under the supercritical water environment are revealed; at the particle scale, the critical fluidization velocity changes of supercritical water hydrogen production fluidized bed reactors with different particle size distributions are studied. The scale-up criterion for supercritical water fluidized bed reactor is proposed at the reactor scale.

Brief Introduction of Lecturer:
