摘要:
The invention relates to a mixed salt composition which is useful as a CO2 sorbent. The mixed salt composition comprises a Mg salt, and at least one Group IA element salt, where the Mg and Group IA element are present at a molar ratio of from 3:1 to 8:1. The resulting composition can adsorb about 20% or more of CO2 in a gas. Via varying the molar ratios of the components, and the Group IA element, one can develop compositions which show optional functionality at different conditions. The composition is especially useful in the adsorptive capture of CO2 on mobile sources, such as transportation vehicles, where it can be recovered during regeneration of the adsorbent composition and the CO2 used as a coolant gas, as a reactant in manufacture of fuel, and so forth.

The present invention provides a method of increasing the efficiency of exothermic CO2 capture processes. The method relates to withdrawing heat generated during the exothermic capture of CO2 with various sorbents via heat exchange with a working fluid. The working fluid is provided at a temperature and pressure such that it is in the liquid state, and has a vaporization temperature in a range such that the heat arising from the reaction of the CO2 and the sorbent causes a phase change from liquid to vapor state in whole or in part and transfers heat from to the working fluid. The resulting heated working fluid may subsequently be used to generate power.

A method and apparatus directed to formation of a connection with an ultrasonic transducer apparatus (UTA) comprising a transducer device having first and second electrodes is provided. The UTA is engaged with an interposer device surface. The interposer device is greater in at least one lateral dimension than and extends laterally outward of the UTA, and comprises at least two laterally-extending conductors. A conductive engagement is formed between the first and second electrodes and respective first ends of the conductors. A connection support substrate is engaged with the interposer device about second ends of the conductors, and includes at least two connective elements for forming a conductive engagement with the respective second ends of the conductors. The UTA is then inserted into a catheter member lumen such that the device plane of the UTA and the at least two connective elements extend axially along the lumen.
