Abstract: PURPOSE: A carbon dioxide adsorbent is provided to be able to be operated at a high temperature, to have an excellent capture capacity of carbon dioxide, and therefore, to be able to be usefully used in adsorption of pre-combustion carbon dioxide as well as carbon dioxide generated in combustion. CONSTITUTION: A carbon dioxide adsorbent (10) includes a porous inorganic oxide (1) having multiple mesopores (5), and active compounds combined to the surface of the mesopores. The active compounds are selected from alkali metal-containing compounds, alkali earth metal-containing compounds and a combination thereof. The mesopore has an average pore diameter of 2-50 nm. The porous inorganic oxide is selected from silica, alumina, titania, zirconia, tin oxide, cobalt oxide, zinc oxide, indium oxide, nickel oxide, hafnium oxide, vanadium oxide and a combination thereof. A manufacturing method of the carbon dioxide adsorbent comprises a step of providing an acidic aqueous solution; a step of adding an inorganic oxide precursor to the acidic aqueous solution to hydrate; a step of adding an active compound precursor selected from alkali metal-containing compounds, alkali earth metal-containing compounds, and a combination thereof and drying; and a step of plasticizing the dried product.

Abstract: A power saving circuit reduces a power-consumption in a standby state by adding an additional power saving circuit to TVCR(television & video & cassette & recorder). The circuit includes: a full-wave rectifier for outputting a DC power; a power value converter for converting the DC power into at least predetermined DC powers; a standby power reduction controller which connects the DC power from the full-wave rectifier to the power value converter, or cuts off a connection between the DC power and the power value converter; a key input means having a standby state power saving key; a main controller for outputting the power saving control signal by selecting the standby state power saving key; and an auxiliary power supply means for providing the standby power to the main controller in a system standby state wherein a DC power is cut off.
