Abstract: front page image
(EN) FIELD: chemistry. SUBSTANCE: applied is a mechanic mixture of a thermally regenerated sorbent - carbon dioxide absorbent, which represents potassium carbonate, fixed in pores of titanium dioxide, and has the following composition: wt %: K2CO3 - 1-40, TiO2 - the remaining part to 100, and a photocatalyst for the process of methanation or reduction of a composition separated in the process of the carbon dioxide regeneration: wt %: Pt≈0.1-5 wt %, CdS≈5-20 wt %, TiO2 - the remaining part to 100, the content of the photocatalyst in the mixture constitutes 10-50 wt %. EFFECT: method represents an energy effective method of obtaining methane from air carbon oxide, applies alternative renewable energy for the fuel synthesis. 5 cl, 4 ex, 1 dwg
(RU) Изобретение относится к способу получения метана из атмосферного диоксида углерода. Способ характеризуется тем, что используют механическую смесь термически регенерируемого сорбента - поглотителя диоксида углерода, который представляет собой карбонат калия, закрепленный в порах диоксида титана, и имеет состав: мас%: K2CO3 - 1-40, TiO2 - остальное до 100, и фотокатализатора для процесса метанирования или восстановления выделяемого в процессе регенерации диоксида углерода состава: мас.%: Pt≈0,1-5 мас.%, CdS≈5-20 мас.%, TiO2 - остальное до 100, содержание фотокатализатора в смеси составляет 10-50 мас.%. Данный способ представляет собой энергоэффективный способ получения метана из диоксида углерода воздуха, использует альтернативную возобновляемую энергию для синтеза топлив. 4 з.п. ф-лы, 4 пр., 1 ил.
