Abstract
The invention discloses a process for producing lignin diesel. The method is characterized by comprising the following steps of: uniformly mixing the components of an emulsifier in a ratio, forcibly dispersing the uniformly mixed emulsifier and diesel by a physical means to obtain a stable dispersing system, then adding assistant emulsifier and an oil modifier in a certain ratio, injecting decolored alkali lignin aqueous solution from which impurities are removed into the system at a constant speed, continuously dispersing cyclically for certain times, taking out and naturally settling for 1 to 2 days, and filtering to obtain supernate, namely the lignin diesel. In the process, the lignin diesel is prepared from the waste lignin used as raw materials instead of partial diesel. The process has the advantages of simplicity, easiness in amplification, and industrialization and the like.
Description
Technical field
The present invention relates to the act as a fuel fuel production technology of additive of a kind of biomass, particularly a kind of diesel oil emulsification production technique that contains xylogen with energy-conserving and environment-protective, long preservative period, advantage such as easy to use.
Technical background
Xylogen is a class material that is made of the polymeric aromatic alcohol, is respectively: to a kind of complicated phenol polymer that four kinds of alcohol monomers of tonquinol, lubanol, 5-hydroxyl lubanol, sinapyl alcohol form, be a kind of many rings macromolecule organic that contains many negative electricity group.It is one of composition that constitutes plant cell wall, and mainly between cellulosic fibre, it is formed and the character more complicated, has the effect that strengthens cell walls and binder fibre in plant tissue.In xylophyta, xylogen accounts for 25%, is second organism the abundantest in the world.
In theory, xylogen is the highest natural high moleculer eompound of occurring in nature unit volume energy density, the xylogen combustion heat is 26.6kJ/g, be that inexpensive (1500～2000 yuan/ton) contain natural carbon containing, hydrogen that can be the highest, the macromolecular compound of oxygen, suitable with the ethanol combustion heat 30kJ/g of same carbon containing, hydrogen, oxygen, but because of xylogen than great, its volume combustion heat then is about 1.5 times an of alcoholic acid, close with diesel oil, and the spontaneous ignition temperature and the diesel oil of xylogen are close, make it be suitable for mixing the back with diesel oil and light acting in the diesel engine cylinder inter-sync.Therefore, the genetic prerequisite that has alternative diesel oil.
In fact, the mankind just begin xylogen is studied from nineteen thirty, American in 1980 advises xylogen mixed with diesel oil and substitutes diesel oil, but stable dispersion and the transportation problem of xylogen in diesel oil when all not solving xylogen as the diesel oil alternative fuel technically.Also promptly owing to never search out suitable dispersion agent or emulsifying agent, fine granular xylogen is as contain the power fuel that the inflammable high energy fuels of oxygen can not be used as modern engine in the past always.
Patent CN 101735871 A (quasi-liquid fuel for internal combustion engines and conveying thereof and injection method), CN 101724475 A (biomass base liquid fuels, utilize method and engine structure), CN 101792684 A (oil engine or gas-engine quasi-liquid fuel) and CN 101798534 A (oil engine or internal combustion turbine quasi-liquid fuel) disclose one group and have utilized xylogen polymolecularity and mobile characteristics, by dispersion medium or emulsifying technology, make xylogen subparticle and diesel oil uniform mixing as a kind of quasi-liquid fuel between liquid and solid, partly substitute diesel oil.This method is complex process not only, and to get particle diameter big for the xylogen particle in the fuel that makes, and is extremely unstable, and the oil feeding system of oil engine must be carried out corresponding transformation and could be used very difficult realization industrialization.
And alkali lignin is soluble in water, is insoluble to diesel oil.The present invention just be based on change the aqueous solution that thinking proposes to be dissolved with alkali lignin and diesel oil form even one stablize diesel oil emulsification, with this solve that the xylogen addition of xylogen diesel oil is low, poor stability, defect of high cost.
Summary of the invention
The present invention relates to the act as a fuel fuel production technology of additive of a kind of biomass, particularly a kind of diesel oil emulsification production technique that contains xylogen with energy-conserving and environment-protective, long preservative period, advantage such as easy to use.
At first each prescription of emulsifying agent is mixed in proportion, after the emulsifying agent that mixes and diesel oil adopted physical means is powerful to disperse to obtain stable dispersion system, add a certain proportion of assistant for emulsifying agent and oil product modifying agent then, the alkali lignin aqueous solution that will decolour at last after the removal of impurities at the uniform velocity injects above-mentioned system, continue circulation and disperse certain number of times, took out natural subsidence 1～2 day, filtering gained supernatant liquid promptly is xylogen diesel oil.
Advantage of the present invention:
1 technical process of the present invention is simple, easy and simple to handle, and favorable reproducibility is with low cost, is easy to be amplified to industrialization production.
2 gained xylogen diesel oil content of lignin height of the present invention, system is stable, good fluidity.
The applied xylogen of 3 the present invention is a trade waste, measures inexpensively greatly, and turning waste into wealth is a kind of energy and material, is a kind of recycling economy industry pattern.
4 the present invention can provide new approaches for the energy strategy deposit plan of country.
