|PCT/KR2011/008196||KOREA ELECTRIC POWER CORPORATION||EOM, Tae Hyoung|
The present invention relates to a method for manufacturing a carbon dioxide absorbent and to the absorbent manufactured by the method. The method comprises: (A) a step of preparing a slurry composition including a carrier composition containing a support, an inorganic binder, and a solvent; (B) a step of preparing solid particles by spray drying the thus-prepared slurry composition; (C) a step of manufacturing a carrier by dry calcining the thus-prepared solid particles; and (D) a step of receiving an amine compound into the pores of the thus-manufactured carrier. According to the absorbent of the present invention, an absorbing reaction and a regenerating reaction at a low temperature range (less than or equal to 100°C may be conducted, and therefore, the cost for capturing CO2 in a dry capturing process may be expected to decrease.

|PCT/NZ2012/000203||LIGNIN POLYMERS LIMITED||BATHURST, Christopher Francis|
A continuous flow wood processing technology for extracting lignin from woody plant material and converting the delignified cellulosic residue to crude bio-oils is provided. Wood is chipped before processing starts and fed into a lignin extractor. The lignin extractor uses ethanol at high temperatures to dissolve the lignin with counter current material contactors and heat exchangers and a computer control system to control the operation. Most of the preservative chemicals are likely to precipitate out at this stage as a heavy sludge which can be removed from the process. The ethanol containing dissolved lignin is removed from the lignin extractor, the dissolved lignin recovered, the ethanol being recycled into the lignin extractor and the residual heat returned to the process. The delignified cellulosic pulp is removed from the lignin extractor and subjected to a milling operation to convert the pulp into a smooth sludge for entry to a bio-convertor by a super critical water process. The residue is prepared as a high phosphate Fertilizer. Also described is a process for the removal of toxic preservative chemicals from waste timber and conversion to useful or nontoxic forms.
