A novel carbon absorption material is described which is formed from anaerobic digestate. The material has a hollow tubular structure and is particularly advantageous in converting hydrogen sulfide in biogas and in absorbing the converted sulfur and sulfur compounds from biogas into its structure. The material after use as a hydrogen sulfide absorbent has value as a horticultural or agricultural product or as a sulfur impregnated activated carbon. The process for producing this novel carbon absorption material is described. In an embodiment, the process described uses in particular, a humidified inert gas over a temperature range of between about 500&#xb0; C. to 900&#xb0; C. to convert anaerobic digestate to an active carbon absorbent. The thermal treatment is relatively mild and retains the fibrous structure of the source material while removing cellulosic and hemicellulosic components from the anaerobic digestate.

Methods of sequestering carbon dioxide (CO) are provided. Aspects of the methods include precipitating a storage stable carbon dioxide sequestering product from an alkaline-earth-metal-containing water and then disposing of the product, e.g., by placing the product in a disposal location or using the product as a component of a manufactured composition. Also provided are systems for practicing methods of the invention.

A low-energy method and system of forming hydroxide ions in an electrochemical cell. On applying a low voltage across the anode and cathode, hydroxide ions form in the electrolyte containing the cathode, protons form at the anode but a gas e.g. chlorine or oxygen does not form at the anode.

Low energy electrochemical hydroxide system and method

An electrode of use in electrolytic cells, particularly water electrolyser cells for the production of hydrogen, and comprising an electrically conductive first metal sheet having an electrochemically active gas-evolving planar surface; an electrically conductive second metal electrochemically active gas-evolving screen intimately adjacent and parallel to the planar surface to define an electrolyte and gas-evolving chamber between the sheet and the screen having a narrow width. The electrode provides improvements in voltage and efficiency, longer-term electrode stability and opportunity for periodic depolarization.

Self supporting members of copper containing phosphorus, for example bulk copper anodes or plates, for use as consumable anodes for copper electrodeposition or for melting for alloy production are manufactured by electrodeposition from an electrolyte containing copper ions and a suspension of phosphorus bearing particles having a phosphorus concentration of up to about 5 grams per liter.
