Abstract
The invention belongs to the technical field of clean energy, and in particular relates to an ethyl levulinate-diesel oil mixed fuel. The fuel comprises the following components in percentage by volume: 10 to 30 percent of ethyl levulinate, 64.37 to 89.79 percent of commercial No.0 diesel oil, 0 to 5 percent of cosolvent, 0.2 to 0.6 percent of cetane number improver and 0.01 to 0.03 percent of flash point improver. Various indexes of the fuel meet the indexes of commercial diesel oil, and the oil consumption quantity and the oil consumption rate of the fuel are equivalent to those of the diesel oil; and the fuel has stable performance and can enable a diesel engine to work stably and reliably, the safety and the explosion resistance of the fuel can meet the safety requirement of the fuel for vehicles, and meanwhile, the fuel can achieve the effects of saving energy and reducing emission to a certain extent.
Description
Technical field
The invention belongs to the clean energy technology field, particularly a kind of ethyl levulinate diesel blended fuel.
Background technology
Along with the traditional energy based on fossil oil is day by day exhausted, substitute energy more and more obtains people's attention.Biomass energy is to be only second to coal, oil and natural gas and the energy that occupies world energy sources total quantity consumed the 4th, and is renewable energy source.The scale operation biomass fuel helps to ensure energy security, developing agricultural economy and promotes energy-saving and emission-reduction.With biomass liquid-phase hydrolysis product levulinic acid is that the ethyl levulinate that raw material makes can partly substitute conventional diesel fuel, and can reduce pollution, for improving China's energy structure, realizes that Sustainable development has great importance.
Summary of the invention
The object of the present invention is to provide a kind of mixed clean fuel ethyl levulinate diesel blended fuel, substitute diesel oil, improve energy structure with part.
The technical solution used in the present invention is as follows:
A kind of ethyl levulinate diesel blended fuel, its volume percentage composition is as follows:
Ethyl levulinate 10%～30%, commercial 0# diesel oil 64.37%～89.79%, solubility promoter 0%～5%, cetane number improver 0.2%～0.6%, flash point improver 0.01%～0.03%.
Described solubility promoter is that carbon atom quantity is one or more the mixture in the straight chain saturated fatty alcohol of 4-8, more preferably butanols.
Preferably, the ethyl levulinate diesel blended fuel can carry out proportioning by following volume percent:
The volume percentage composition of propellant combination is as follows: ethyl levulinate 10%, commercial 0# diesel oil 89.79%, cetane number improver 0.2%, flash point improver 0.01%.
Perhaps be ethyl levulinate 20%, commercial 0# diesel oil 76.58%, butanols 3%, cetane number improver 0.4%, flash point improver 0.02%.
Perhaps be ethyl levulinate 30%, commercial 0# diesel oil 64.37%, butanols 5%, cetane number improver 0.6%, flash point improver 0.03%.
Described cetane number improver and flash point improver select the commercially available prod to get final product.
When obtaining described propellant combination, by volume ethyl levulinate, commercial 0# diesel oil, solubility promoter butanols, cetane number improver, flash point improver are mixed in same container and get final product, each composition adds order does not have particular requirement.
The present invention adds solubility promoter, cetane number improver and the flash point improver of low ratio in the propellant combination of ethyl levulinate and diesel oil to, make it can stable for extended periods of time not stratified, wherein, cetane value and flash-point all are on close level with commercial diesel oil, can make the reliable and stable work of diesel motor, oil consumption and rate of fuel consumption and diesel oil are on close level, and can be used as the alternative fuel of diesel oil.
The present invention has following advantage with respect to prior art:
1, every technical indicator of product of the present invention all reaches the index of commercial diesel oil.This product replaces diesel oil to use, and the result of use on engine can reach commercial diesel oil level, and oil consumption and rate of fuel consumption and diesel oil are on close level; And product performance of the present invention are stable, can make the reliable and stable work of diesel motor, security, and anti-bomb all can satisfy the vehicle fuel safety requirements.2, ethyl levulinate is made by the biological material hydrolysate, and its combustion heat value is higher, and extra discharge harmful can not reach the effect of energy-saving and emission-reduction to a certain extent.
