Environment-friendly and energy-saving additive used for fuel and preparing method thereof

The invention relates to an environment-friendly and energy-saving additive used for fuel and a preparing method thereof, and belongs to energy cleaning technologies. The environment-friendly and energy-saving additive used for the fuel is characterized by being prepared from, by weight, 0.002-0.004 part of biological enzyme, 0.001-0.003 part of coenzyme preparation, 0.3-0.5 part of plant extracts, 25-30 parts of petroleum distillation as a carrier, 0.001-0.005 part freeze-dried powder of Bacillus licheniformis with the content of viable count of (2*109)-(3*109) cfu/g. The provided additive added in the fuel can reduce the viscosity of the fuel to make the fuel become oxidizing combustible, improve burnout performance and a low oxygen combustion feature of the fuel, and reduce discharge of oxynitride, oxysulfide and hydrocarbon after the fuel burns. 本发明涉及种用于燃油的环保节能添加剂及其制备方法，属于能源清洁技术，其特征在于包括以下重量组份：生物酶：0.002－0.004份、辅酶制剂：0.001－0.003份，植物提取物：0.3～0.5份，作为载体的石油馏出物：25～30份；活菌数含量为2×10-3×10cfu/g的地衣芽孢杆菌(Bacillus lichenifo
