摘要:
An object of the present invention is to provide a carbon dioxide absorbing solution capable of avoiding precipitation of a product formed by the reaction with carbon dioxide. The absorbing solution is an aqueous solution characterized by containing an amino acid salt comprising at least one carboxylic acid salt connected to a heterocyclic ring including at least one nitrogen atom as the ring member atom.

The present invention provides a method of treating fats and oils containing low concentrations of aromatic halogen compounds and other contaminants by contacting the fats or oils with an adsorbing agent. The adsorbing agent contains a porous body and a non-protonic polar solvent held in the interiors of fine pores in the porous body to adsorb the contaminants. In one embodiment, the porous body also carries noble metal fine particles. In another embodiment, the adsorbing body comprises a solid acid for adsorbing the contaminants and there is a step of contacting the adsorbing body with an organic solvent to extract the adsorbed contaminants into the organic solvent.
摘要:
A method for manufacturing hydrogen includes supplying ethanol to a reactor which is filled with a reforming catalyst and a carbon dioxide absorbent containing a lithium composite oxide, and heating the reactor under the condition that the inside thereof is pressurized to 3 to 15 atm to carry out water-vapor reforming of the ethanol.
摘要:
The carbon dioxide absorbent contains a lithium-containing oxide, an alkali halide, has a high carbon dioxide absorption capability, and sufficiently maintains the carbon dioxide absorption capability even in repeated used for absorption and desorption of carbon dioxide.
