584-08-7 | Potassium Carbonate

Chemical type

• Inorganic salt (carbonate-based)

^[1]

• Inorganic alkaline salt
• Hydrated form: K₂CO₃·1.5H₂O

^[2]

Key properties

• Low reaction rate but high CO₂ loading
• Regeneration energy of 2.6–3.1 GJ/ton CO₂
• Low corrosivity and cost
• Promoted with glycine or DEA for enhanced kinetics

^[1]

• Regulates acid-base balance
• Source of potassium (K)
• Mitigates ruminal acidosis from high-concentrate diets
• Enhances heat stress tolerance in hot conditions
• Increases ruminal acetate and isovalerate concentrations
• Shifts rumen lipid biohydrogenation to favor beneficial isomers (e.g., increases cis-9,trans-11 conjugated linoleic acid and trans-11 18:1; reduces trans-10,cis-12 conjugated linoleic acid and trans-10 18:1)

^[2]

• Hot carbonate process for CO₂ removal from natural gas
• Green alternative in hybrid systems

^[1]

• Dietary supplement in dairy cow feeds (doses: 250–750 g/d per head)
• Improves milk fat and protein percentages (optimal at 500 g/d)
• Enhances rumen fermentation and microbial metabolism
• Boosts amino acid biosynthesis, long-chain fatty acid biosynthesis, and fatty acid elongation pathways in rumen microbiota

^[2]

Classification by use

• Inorganic solvent for bulk CO₂ absorption
• Solvents in low-cost, environmentally benign processes

^[1]

• Feed additives for nutritional regulation
• Buffers for rumen pH and acid-base balance
• Supplements for improving dairy production performance and animal welfare
