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.

In the method for conversion with recovery of energy carriers in a cyclical process of a thermal engine, a first recirculation cycle is formed involving gas generator, device for converting kinetic and thermal energy into mechanical energy, hydrogenation reactor, and gas generator. Water is evaporated in steam boilers, and steam is fed into turbine for converting steam energy into mechanical energy. In this process, steam boilers are located in gas generator and in hydrogenation reactor. The steam is carried onward from conversion device into condenser, and a second recirculation cycle is formed. Atmospheric oxygen from an air bubble is supplied to gas generator. The air is cooled, and cooling operation is repeated, until a maximum residual water content in the air of 0.2 g/m3 is attained. Formed condensate is collected and used steam boilers. Invention makes it possible to simplify process of recovering carbon oxides formed in thermal engines.
