Patent number: 9108859Abstract: An engineered process of manufacturing a carbon capturing agent calcium aluminum carbonate Ca—Al—CO3 includes steps of mixing, solid-liquid separation, drying and extrusion, crushing and conveying, and calcined molding. The acid bath of Ca+2 and Al+3 is mixed with the alkaline bath of Na2CO3 and NaOH while stirring to form slurry which are then subject to solid-liquid separation to obtain a filtrated cake. The filtrated cake is place into a drying and extrusion device to obtain granular material. The granular material is placed in a conveying and crushing equipment to obtain a powder material. The powder material is calcined at furnace for forming a Ca—Al—CO3, which is nano-layered composite with high porosity. Thereby, the preparation of a solid sorbent can be scale up under systematically controlled with yield of at least batches of kilograms used in medium-high temperature (400˜800° C.) CO2 capture.Type: GrantFiled: September 13, 2012Date of Patent: August 18, 2015Assignee: INSTITUTE OF NUCLEAR ENERGY RESEARCH, ATOMIC ENERGY COUNCILInventors: Ching-Tsung Yu, Yau-Pin Chyou, Wei-Chin Chen, Wun-Syong Chen

Patent number: 8754002Abstract: A dry material is synthesized by alkali metal (Li, Na and K) promoted calcium aluminate carbonates to obtain a CO2 sorbent used at a temperature higher than 600 Celsius degrees (° C.). The key composition of the sorbents is 52˜69% of CaO, which is beneficial to capture CO2 at 400˜800° C. A breakthrough result is achieved by using this sintering-resistant sorbent, which includes the features of 50% initial carbonation capacity and 20 folds CO2 capturing performance maintained after 40˜60 hours. Besides, alkali bearing material provides good velocity in CO2 capturing/releasing cycles; for example, by using Li and K series sorbents, 40 hours is required for 40 cycles only.Type: GrantFiled: July 11, 2011Date of Patent: June 17, 2014Assignee: Institute of Nuclear Energy Research, Atomic Energy CouncilInventors: Ching-Tsung Yu, Chi-Hung Wang, Yau-Pin Chyou

Publication number: 20060025304Abstract: Disclosed is a radiation sensitive photocatalyst composition and application thereof. The composition can be induced by using ionization radiation or non-ionization radiation, which comprises a photocatalyst to perform photocatalysis; an enhancer to convert radiation energy into photons for photocatalysis; and a porous material to absorb and to immobilize the photocatalyst/enhancer becoming a composition system. The advantages of using radiation to carry out the photocatalytic reaction for environmental protection are high permeability as well as time flexibility in comparison of artificially UV/natural solar radiation. Anyway, the present invention can be used to fulfill the environmental application such as volume-reduction of spent radioactive resin and organics degradation. It is worthy to explore the regeneration of hydrogen energy by this invention.Type: ApplicationFiled: June 3, 2005Publication date: February 2, 2006Inventors: Chu-Fang Wang, Ching-Tsung Yu, Jeng-Hung Lee
