On the basis of process simulation and basic theoretical analysis, a new energy saving double-column process is proposed for FCC absorption and desorption system with "bi-directional mass transfer".
From the microscopic view point ofenergy transfer, energy transfer mechanism of femtosecond pulse laser radiation on metal film and the resulted molecules desorption from substrate is discussed.
Taking solar energy as a drive thermal resource, the static temperature distribution at some time, the dynamic state change of temperature, pressure and desorption speed with time was analyzed.
