Title: Harmonic adsorption recuperative power systems and methods

Abstract

A new power generation thermodynamic cycle is described that eliminates need for bulk liquid condensation and vaporization steps required in conventional ORC power systems. An exemplary harmonic adsorption recuperative power cycle system offers more efficient power generation as compared with conventional ORC systems. A multibed adsorption system is used to provide thermal compression for the cycle. An adsorption compressor contains a sorbent with strong adsorption affinity for the working fluid in the pores while well outside the P-T conditions needed to condense the liquid phase, allowing the adsorption compressor to reduce operating pressure exiting the expander.
