NOVELTY - High-efficiency coal-saving agent with low doping amount prepared by blending solid component and liquid component, where the solid component comprises 15-25 pts. wt. sodium chloride, 7-11 pts. wt. ammonium persulfate, 4-8 pts. wt. cerium nitrate, 22-28 pts. wt. polyoxyethylene ether, 6-10 pts. wt. potassium chlorate and 10-15 pts. wt. calcium chloride, and the liquid component comprises 18-25 pts. wt. sodium lignosulfonate, 2-3 pts. wt. graphene and 5-6 pts. wt. hydroxypropyl methylcellulose, is claimed. USE - Used as high-efficiency coal-saving agent with low doping amount. ADVANTAGE - The coal saving agent: is in liquid state, mainly suitable for various lignite, coke, bituminous coal and anthracite; and has efficient coal saving under the condition of low dosage, more significant effect on low calorific value coal, and wider application prospect compared with most domestic coal saving agents. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the high-efficiency and coal-saving agent with low doping agent, comprising (i) taking each raw material to prepare solid component and liquid component respectively, and (ii) mixing solid component obtained in the step (i) with the liquid component, heating to 72-80degrees Celsius, ultrasonically stirring and processing for 15-25 minutes, and cooling to obtain the finished product.
