Coupling of exothermic and endothermic hydrogen storage materials

Integrated design and control of plantwide systems coupling exothermic and endothermic reactions

The problem of integrated design and control of plantwide systems coupling endothermic and exothermic reactions is addressed. Processes simultaneously carrying on the endothermic first-order reaction A→R+Q and the exothermic second-order reaction B+Q→P are considered. As the physical properties of the species involved vary, possible flowsheets are identified and feasible control strategies are ...

Endothermic freezing on heating and exothermic melting on cooling.

Generally, a liquid freezes exothermally on cooling and a crystal melts endothermally on heating. Here we report an opposite occurrence--a liquid's endothermic freezing on heating and the resulting crystal's exothermic melting on cooling at ambient pressures. C(p) decreases on freezing and increases on melting, and the equilibrium temperature meets the thermodynamic requirement. Melting on cool...
