Method for converting energy, increasing enthalpy and raising the coefficient of compressibility

A method of converting thermal energy into mechanical energy, comprising introducing a catalytic additive into a working fluid;

• imparting thermal energy, sufficient to transfer the working fluid from liquid to vapor phase, to the working fluid in a tank;
• feeding the working fluid in the vapor phase into a device for converting energy into mechanical work with expansion of the vaporous working fluid and reduction in temperature and pressure;
• condensing the vaporous working fluid;
• cyclically returning the working fluid in the liquid phase into the tank, wherein said introducing of a catalytic additive into a working fluid is accomplished before or after said imparting of thermal energy thereto;
• a catalytic substance or a catalytic mixture of substances is used as the catalytic additive in the form of a solid, a solution or suspension thereof or a liquid or emulsion thereof;
• said catalytic substance or at least one substance in the catalytic mixture comprises at least one carbonyl functional group and has at least one intense absorption band in the region from 1550 to 1850 cm−1 in the IR spectrum;
• the additive is introduced in an amount ranging from 0.0000001 to 0.1 wt. %, and the catalytic substance and the weight ratio of individual substances in the catalytic mixture are chosen to prevent or promote decomposition of the substance or the mixture under the effect of high pressure and temperature in accordance with current needs.
