A review on CO2 capture with chilled ammonia and CO2 utilization in urea plant

Carbon neutral methanol from pulp mills towards full energy decarbonization: an inside perspective and critical review

“…In fact, considering the specific case of CO 2 capture for e-methanol production, it is necessary to consider the cost competitiveness of the process with other CO 2 uses and applications, such as fuel production through CO 2 fixation by microalgae 44 and the Fischer-Tropsch route, 45 as well as other pathways towards distinct chemicals and fertilizers. 46,47 For this purpose, this work provides an overview and critical review of the integration of distinct biomethanol and e-methanol production processes in the P&P industry, including current technological and market drivers and barriers, as well as opportunities and potential synergies. Novel integrated biorefinery designs involving thermochemical technologies and PtL concepts are also proposed to harvest biogenic CO 2 and efficiently transform it into green methanol.…”

Absorption Kinetics of CO2 in Aqueous Ammonia with High Load and Salinity

“…Post-combustion carbon capture (PCC) technology of the flue gas is the most widely applied technology in the coal-fired power plants, mainly including absorption, adsorption, and cryogenic methods. Considering the low partial pressure of carbon dioxide (CO 2 ) in the flue gas of coal-fired power plants, the large flue gas volume, and the maturity of technology, compared with other CO 2 separation principles, the chemical absorption method is a more suitable choice at present . Among the existing chemical absorption methods, researchers have proposed to replace the traditional monoethanolamine (MEA) absorption method with inorganic ammonia carbon capture (IACC) in recent years. , Also, the results of explored studies of the technical and economic feasibility of CO 2 removal from flue gas by aqueous ammonia − showed that aqueous ammonia, as an absorbent, on the one hand, can achieve the combined removal of pollutants from flue gas of power plants and, on the other hand, can ensure the original production efficiency of power plants, which has a broad application prospect.…”

A series of bifunctional metalloporphyrins as efficient catalysts for cycloaddition of CO2 with epoxides

“…As is known to all, carbon dioxide (CO 2 ) is a ubiquitous, non-toxic, and inexpensive carbon resource, 1,2 and the chemical conversion of CO 2 has attracted extensive attention of chemists in various countries. For example, in industry, CO 2 is used as raw material to synthesize urea, 3 methanol, [4][5][6] polycarbonate, 7 and cyclic carbonate. 8,9 Among them, the 100% atom-economical cycloaddition reaction of CO 2 and epoxide to produce cyclic carbonate has the most promising development for the excellent market application value of cyclic carbonate in lithium batteries, 10 polymer materials, 11,12 fuel, 13 and other new energy fields.…”
