Abstract:
The present invention relates to an amine-polymer CO_2 adsorbent which does not need a molding process for using a spherical polymer support, and has excellent performance by adding a surfactant as an additive. The adsorbent, generated by various aspects and embodiments of the present invention, uses the polymer support in a globular shape, and thus does not need a molding process, and a conformational change of water does not occur.

Abstract:
PURPOSE: A design of a support structure for optimizing a solid oxide fuel cell stack is provided to minimize electricity loss from a positive electrode, and to maximize the power per unit volume. CONSTITUTION: A design of a solid oxide fuel cell (20) comprises a hexagonal pipe type fuel electrode support (22) formed of six outer peripheral surfaces; a solid oxide electrolyte layer formed on the entire surface of the fuel electrode; an air electrode (23) formed on the entire surface of the solid oxide electrolyte layer; and a fuel electrode connector (24) and an air electrode connecter (25) which are alternately installed in the six planes. The solid oxide fuel cell stack is obtained by laminating a plurality of solid oxide fuel cells.
Abstract:
본발명은아민간 가교를형성하는아민구조개선과다공성지지체내에코어/쉘구조형성을통해장기흡탈착성능뿐만아니라입자의유동성이증진된 CO흡착제및 이를제조하는방법에관한것으로서, 본발명에따른이산화탄소흡착제는가교제에의해서가교되어구조가개선된아민을포함하는층을구비하고있어서요소가형성되는등의비가역적인부반응을일으키지않아반복재사용시에도이산화탄소흡착량이매우우수하게유지된다. 또한, 아민기끼리가교된아민구조체가다공성지지체내부에형성되어있어아민기가침출하지않아침출된아민에의해흡착제가뭉치는현상이발생하지않으므로장기적으로흡착량이유지된다. 또한, 가교아민의경우점도및 분자량이높아지지체내부에함침이어려우나, 본발명에따른이산화탄소흡착제의제조방법은가교제와아민을지지체기공내에서반응시키므로가교가일어나기전에아민을지지체에함침시키는특징을가져서함침율이매우우수하다. 또한, 가교제는함침된아민물질의 1차아민과반응하여 1차아민의비율을감소시켜요소생성부반응을억제하여높은이산화탄소흡착능을유지할수 있다.
