Abstract: Apparatus for the production of carbon dioxide from limestone includes a nuclear energy source (32) arranged to generate electricity and a rotary kiln (10). The rotary kiln (10) has an inlet (15) for the introduction of limestone and an outlet (19) for the release of carbon dioxide. An electrical resistance heating element (21) disposed within the kiln (10) is arranged to be supplied with electricity derived from the nuclear energy source (32) to raise the temperature of the element (21) for transfer of heat to the interior of the rotary kiln (10). Limestone in the rotary kiln (10) is thereby heated to a temperature sufficient for the release of carbon dioxide.

Abstract: A system (10) for producing carbon monoxide as a step in a process for the production of carbon neutral fuel includes heating apparatus (11) arranged to heat coal to produce coke and a limekiln (32). The limekiln (32) has an inlet (34) for the introduction of limestone, a heater (35) for heating limestone contained therein and an outlet (36) for the release of carbon dioxide. A coke chamber (39) is operatively connected to the heating apparatus (11) to receive coke therefrom and is operatively connected to the limekiln outlet (36) to receive carbon dioxide therefrom. The coke chamber (39) is configured to react received coke with received carbon dioxide, thereby to produce carbon monoxide.
