Biomass fuel oil and preparation method thereof

Abstract

The invention relates to biomass fuel oil. The biomass fuel oil comprises the following components in percentage by weight: 10 to 15 percent of vegetable oil, 10 to 40 percent of bio-alcohol, 5 to 15 percent of bio-diesel, 0 to 5 percent of fatty acid, 5 to 15 percent of mutual solvent, 0 to 10 percent of combustion accelerant, 0.1 to 1 percent of solid base catalyst, 0.1 to 1 percent of combustion improver, 0.1 to 0.5 percent of oxygenate and 0.1 to 0.5 percent of detergent. A preparation method of the biomass fuel oil comprises the following steps of: a, adding and uniformly stirring the vegetable oil, the bio-alcohol and the mutual solvent in a reaction kettle, adding the solid base catalyst into the mixture and stirring the mixture to form suspension; and b, heating the suspension to 50 to 70 DEG C, making the suspension flow back through a condenser, stirring the obtained product for 10 to 90 minutes, cooling the product to the room temperature, filtering off the solid base catalyst, then sequentially adding the bio-diesel, the fatty acid, the combustion accelerant, the combustion improver, the oxygenate and the detergent and stirring and reacting the mixture for 20 to 30 minutes to obtain the biomass fuel oil. The biomass fuel oil provided by the invention has the advantages of high combustion value, high lubricating property and high flash point.

Description

technical field [0001] The invention relates to the field of fuel technology, in particular to a biomass fuel oil and a preparation method thereof. Background technique [0002] Oil resources are becoming increasingly tense and prices are rising, and there are signs that the era of low oil prices may be gone forever. In order to alleviate the shortage of oil supply and environmental pollution, a wave of renewable energy for the purpose of replacing petroleum energy has been triggered. From fuel ethanol to photovoltaic solar energy to biodiesel, all major countries in the world have received keen attention. In 2007, the Ministry of Energy and the State Environmental Protection Administration jointly announced that diesel will be completely prohibited from entering the kitchen in the next few years. At present, some cities have begun to prohibit the use of diesel in kitchen supplies. In view of the tight supply of petroleum and fuel oil and the huge market demand, the develop...

Problems solved by technology

The main problems of biodiesel are difficult sources of raw materials, high cost and complicated process

At present, biodiesel is generally synthesized by transesterification. The process is long and complicated, and the energy consumption is high, and the equipment investment is large. The follow-up process must have corresponding glycerin and methanol separation and recovery devices, crude product vacuum distillation devices, decolorization and refining. Equipment and other series of equipment and process, production process and waste liquid discharge, etc.
