Abstract: The present invention provides a process for producing an activated carbon having a small average particle diameter, a uniform particle size and a relatively large specific surface area suitable for an electric double layer capacitor electrode, in an easy and cost effective manner. The process comprises calcining an easily graphitizable carbon material such as petroleum coke or coal coke, used as the raw material under an oxidizing gas atmosphere, adjusting the particle size of the carbon material, and then activating the carbon material. The use of the activated carbon produced by the process of the present invention in an electrode can provide an electric double layer capacitor having a large capacitance per unit volume.

Abstract: A process for manufacturing a block of material that imitates natural stone. The manufactured stone not only looks and appears like natural stone, but is also consistent with the composition of natural stone. The process comprises forming an aqueous mixture of limestone aggregates, treating the mixture with carbon dioxide under pressure and then highly compressing the treated mixture in a sealed mold. This process recreates the endogenous matrix of the natural stone and its original composition. The block of material is intended for construction and decoration purposes.

Abstract: A method of producing calcium carbonate from a waste sludge containing calcium carbonate and at least one silicate mineral. The method comprises the steps of: (i) incinerating the sludge to an ash in which at least 60% of the calcium carbonate present in the sludge is converted to free calcium oxide which is unreacted with the silicate mineral(s), (ii) optionally slaking the ash to convert at least a portion of the free calcium oxide therein to calcium hydroxide, (iii) treating either the ash from step (i) or the slaked ash from step (ii) with an aqueous solution of a polyhydroxy compound to provide a solution of dissolved calcium hydroxide, (iv) separating insoluble material from the solution of calcium ions obtained in step (iii), (v) dispersing carbon dioxide through the solution obtained from step (iv) so as to produce calcium carbonate, and (vi) separating the calcium carbonate produced in step (v).

Abstract: The disclosure utilizes a hydroxide sorbent for humidification and CO2 removal from a gaseous stream comprised of CO and CO2 prior to entry into a water-gas-shift reactor, in order to decrease CO2 concentration and increase H2O concentration and shift the water-gas shift reaction toward the forward reaction products CO2 and H2. The hydroxide sorbent may be utilized for absorption of CO2 exiting the water-gas shift reactor, producing an enriched H2 stream. The disclosure further provides for regeneration of the hydroxide sorbent at temperature approximating water-gas shift conditions, and for utilizing H2O product liberated as a result of the CO2 absorption.
