Anode material for lithium secondary battery, process for production thereof, and lithium secondary battery

The present invention discloses an anode material for lithium secondary battery, comprising a particulate core composed of a metal or semimetal capable of forming a lithium alloy and a carbon layer covering the surface of the particulate core; a lithium secondary battery using said anode material; and a method for discharging of said secondary battery.

Anode material for lithium secondary battery, lithium secondary battery using said anode material, and method for charging of said secondary battery

A process for the production of an edible food supplement preservative from a rootcrop by processing such rootcrop into dry powder, the process steps including, placing the rootcrop in a closable vessel, subjecting the rootcrop to chopping or cutting while the vessel is evacuated, effecting a primary drying followed by the injection of an inert gas thereinto, crushing the rootcrop, spraying a synergist onto the crushed mass, spraying a drying distillation liquid thereonto, effecting a secondary drying of the resulting mass and mixing the dried mass to a dispersed state.

A sulfur dioxide-containing gas, for example, one obtained by an SO.sub.x and NO.sub.x removing process using ammonia is treated by the use of a reaction apparatus comprising a reducing reaction portion and a composition controlling oxidation reaction portion, provided in the same reactor or reactors adjacent to each other, to convert the composition of the gas into one suitable for the Claus reaction.

Apparatus for treating a sulfur dioxide-containing gas

An SO.sub.2 -containing gas, in particular, pre-stage gas for the Claus reaction to recover sulfur can effectively be purified by removing NH.sub.3 contained therein using a TiO.sub.2 catalyst.
