Embodiment Construction

[0046]The cleaned power plant exhaust gas passes into a reaction bed with sodium sodium carbonate, and sodium bicarbonate is formed at 40 ° C;

[0047]Add the amount of water in sodium hydrogencarbonate, 5% PD / C (the load amount of Pd on C is 10%), stirring, giving hydrogen, the hydrogen pressure in the reactor is maintained at 1 atmospheric pressure, to be solved The solid disappeared pH keeps constant constant constant, and the solution is evaporated, centrifuged and dried to obtain sodium formate solids;

[0048]The resulting formate solid was reacted at 350 ° C for 35 min, i.e. sodium sodium sodium formate was completed.

[0049]The resulting oxalate is used in different laundry powder formulations, the laundry powder preparation process is as follows:

[0050]In accordance with Table 1 components and content, raw materials are performed. (1) Add deionized water to 50-60 ° C, heating to 50-60 ° C, start stirring; (2) to add anionic surfactant, buffer, sodium carbonate, sodium silicate, an...

Abstract

The invention discloses a method for sequestering carbon dioxide, which is directly applied to the production of oxalate after trapping and absorbing carbon dioxide with an inorganic base. The oxalate is used as a detergent additive in laundry detergent. Salt and calcium ions in water form calcium oxalate crystals, thereby realizing the utilization and mineralization of carbon dioxide. The present invention absorbs carbon dioxide through carbonate and directly uses it in the production of oxalate, avoiding a large amount of energy loss in the regeneration process of the adsorbent, and the whole process can realize zero emission; the oxalate produced from carbon dioxide is used as detergent Additives, through the combination of oxalate radicals and calcium ions during the washing process to form calcium oxalate precipitation, finally realize the mineralization and storage of carbon dioxide and alleviate the greenhouse effect.

Description

Technical field[0001]The present invention relates to a method of using and encapsulating carbon dioxide, and more particularly to the preparation of sodium oxide as a raw material for carbon dioxide and used oxalate to detergent auxiliaries, and to generate calcium carbon dioxide during detergent. The purpose of the storage.Background technique[0002]The main reason for global warming is the emission of greenhouse gases, emissions in greenhouse gases in CO2The amount of contribution exceeds 60%. Among them, fossil fuel power generation, accounting for CO21 / 4 of emissions. In order to meet the electricity needs of daily life, COs discharged to coal-fired power plants2It is an important issue to capture and use.[0003]CO for coal-fired power plants2Question, people put forward different COs2The capture method includes physical adsorption, chemical adsorption, membrane separation, biological fixation, and low temperature separation. The membrane separation is difficult to balance the am...
