Summary of the invention
Oil engine of the present invention or internal combustion turbine quasi-liquid fuel, the firstth, seek a kind of substitute energy with biological material or derivatives thereof of higher energy density as gasoline, kerosene, diesel oil; Second provides all or part of alternative gasoline of a kind of quasi-liquid fuel between liquid and solid or kerosene or diesel oil, still with gasoline, kerosene, diesel oil as delivery vehicles, so that only need minimally to change the structure of existing oil engine or internal combustion turbine, can use, perhaps low-calorie biomass microparticle material be mixed the back with gasoline, kerosene, the diesel oil of high-energy-density and obtain still to have the fuel of the accurate liquid combination of higher energy density as oil engine or internal combustion turbine.
The present invention utilizes the lignin that utilizes the whole bag of tricks to obtain from biological material to be used for all kinds of gasoline, kerosene, diesel oil (light or heavy gas oil or biofuel) explosive motor, as accurate all or part of alternative gasoline of " liquid " fuel or diesel oil fuel.Various pulp and paper making methods are (as soda processes, sulphate process, neutrality or alkali sulfite process, chemical mechanical pulping, the thermomechanical extraction method, organic solvent method) in, or utilize the hydrolysis of various routines, alcoholysis, the ketone hydrolysis, acidolysis, amine catalysis etc. utilizes protolignin or the non-protolignin after the separation or the product or the derived products of fragment behind the lignin degradation or various structures of the chemical reagent method various different chemical structures that separated and dissolved goes out from biomass, or the degraded lignin and part lignin self or with hemicellulose or with saccharan generation condensation reaction after product, be referred to as lignin in the present invention, because the lignin microtexture that different methods obtains, molecular weight varies in size, and the data 26.6KJ/g that provides in its combustion heat and the document should be different to some extent.
Though lignin has advantage, but lignin is insoluble to gasoline, kerosene, diesel oil under the normal temperature user mode, what utilize that lignin at first needs to solve is how lignin and conventional liquid fuel such as gasoline, kerosene, diesel oil effective to be mixed and be conveyed into that jet ignition burns rapidly in the engine cylinder, obviously, by machinery rock, dynamically to keep their mutual mixing and flowability be direct and simple technical scheme for vibrations, stirring method.Be convenient to be conveyed into engine cylinder in order to keep mixing the suspension state, this suspension must stir or vibrations.Present hand tractor is installed on the same support with diesel oil tank and engine cylinder, often move the diesel engine of board R180 type power 8P as Jiangsu, the vibrations that vibrations during the engine operation can keep fuel tank automatically, therefore this vibrating state can be by being fixed on this fuel tank and engine cylinder on the same support, utilizes the vibrations of cylinder to drive not stopping to shake and making the suspension that mixes of lignin and fuel oil directly pass through oil thrower by oil injection pump and spray in the cylinder of fuel tank.
Commercially available alkali lignin is easy to absorb moisture, therefore, before adding fuel oil, preferably carry out acid treatment or pickling after drying dispersion and fining, reduce metal ion or metal oxide in the alkali lignin on the one hand, as sodium ion, calcium ions and magnesium ions etc., one side and reduce water-absorbent also improves the invert point that the glassy phase of lignin changes on the other hand and avoids its softening obstruction at the oil nozzle place.Consider that lignin is easy to take place the condensation polycondensation under acidic conditions, therefore, add trace and fear that quinone, methyl are feared quinone, beta naphthal stops the lignin aggregation to help to prevent the generation of lignin condensation.In addition, add ethanolamine derivative and do additive, contain the oilness of the low-sulfur fuel of lignin with raising.
