Alcohol biomass clean diesel fuel

The invention relates to an alcohol biomass clean diesel fuel oil, which comprises following materials according to weight percentage: mixed ester 60 to 80%, C9 10 to20%, mixed alcohol 8 to 15%, antioxidizer preservative 1 to 3% and emulsifier 1 to 3%. The alcohol biomass clean diesel fuel oil has the advantages of reducing demand of petrochemical fuel petroleum since main material mixed ester can be extracted from various biomass to substitute petroleum fuel, reducing generation cost and saving resources since mixed ester can be extracted from wastes, facilitating thorough combustion of carbon molecule in fuel and greatly reducing discharge of particle dust since the biomass fuel is the mixture with high oxygen content, and reducing discharge of deleterious wastes and generation of carbon deposition and facilitating thorough combustion of fuel due to the decrease of generation amount of oxynitride caused by slight explosion initiated by water in emulsion liquid with alcohol. The alcohol ...

Method for removing pollutants in water by ultrasonic-absorption synergy

The invention relates to a method for removing pollutants in water by ultrasonic-absorption synergy and aims at realizing fast and high-efficiency removal of the pollutants in the water. The method is characterized in that a special absorbing agent (such as diatomite and coal ash) is added in the process of carrying out ultrasonic treatment on the water to be treated so as to be effectively dispersed in the ultrasonic process and enhance the occurrence of the absorption process; simultaneously, due to enrichment of the pollutants on the absorbing agent and the catalytic action of the absorbing agent, the absorption process can intensify the ultrasonic-removing action, so that the synergistic action is generated. In the method, the pollutants in the water are removed by the synergistic action of ultrasonic radiation and the absorbing agent, the needed ultrasonic-radiation energy is lower, the total energy consumption is lower, and the solid absorbing agent is easily and fast removed by the ...
