Abstract
The invention discloses a method for recycling tung seed press cakes to convert into biodiesel; the method comprises the following steps: crushing machine-pressed tung cakes obtained after tung tree nuts are pressed into tung oil, removing impurities, carrying out destructive distillation, cracking, decomposing, and thus obtaining a product reaching the indexes of Chinese No.0 petroleum diesel. The product is put in markets, is selectively checked to conform to diesel engine fuel blending biomass diesel GB/T20828, and is subjected to analysis detection to obtain the results: the cetane number (CN) is not less than 49%, the sulfur content (mass fraction) is not greater than 10 mg/kg, the water content (mass fraction) is not greater than 0.05%, the total glycerol content (mass fraction) is not greater than 0.2%, the acid number (KOH) is not greater than 0.5 mg/g, the sulfate ash content (mass fraction) is not greater than 0.2%, and the ester content (mass fraction) is not less than 96.5%.
Description
Technical field:
The present invention relates to the grouts scrap concrete recycling economy regeneration after wild resource tung tree kernel ejection squeezing Oleum Verniciae fordii,
It is specifically related to the cake after tung oil tree kernel squeezing Oleum Verniciae fordii and prepares biodiesel, belong to agricultural byproducts processing field.
Background technology:
In the face of global minimizing fossil energy consumes, control the form of greenhouse gas emission, utilize biomass energy to substitute fossil
The energy has become inevitable.Biomass energy is the most widest regenerative resource, has renewable, and low stain is widely distributed,
The features such as total amount is abundant.At present, biomass energy accounts for the 11% of global energy utilization, it is contemplated that to mid-21st Century, uses specially
The various biomass substitute fuels that profit technology produces will account for more than the 40% of whole world total energy consumption.It is downloaded from paulownia cake renewable resource utilization today
Conversion biodiesel there is no report.
Summary of the invention:
Technical scheme: the machine after tung tree kernel squeezing Oleum Verniciae fordii squeezes cake → pulverizing → remove impurity → dry distilling → cracking → decomposition
→ product reaches the index of domestic No. 0 petroleum diesel, and step is:
1, the cake after squeezing Oleum Verniciae fordii with organic solvent leaches, and leaching weight of solvent is calculated as 0.8-2.0: 1, and extraction time is 60-200
Minute, the miscella after leaching obtains leaching the weight of oil concentration miscella than 60%-90% after evaporation or refrigerated separation, leaches
After containing wet cake obtain after precipitation residual oil content by weight less than or equal to 1% the defat dregs of rice.
2, the concentration mixed weight that will obtain, carries out biodiesel conversion reaction, reacted product warp after the catalyst of 1-10%
Obtaining biodiesel crude product and glycerol after separation, biodiesel crude product obtains biodiesel oil product through distillation.
Detailed description of the invention:
Tung tree kernel cake after squeezing Oleum Verniciae fordii leach the miscella that obtains preheated to 55 DEG C after enter the first long-tube evaporator
Being evaporated, the concentration concentrating miscella after evaporation reaches 78% by weight leaching oil proportion, adds its weight in miscella
The strength by weight of the methanol of 10% and its weight 1.5% carries out biodiesel conversion reaction than the sodium hydrate methanol solution being 0.7%,
Heating reflux reaction 2 hours, reaction stops stirring after terminating, and glycerol starts to separate out, and quiet to 2 hours, isolates lower floor's glycerol
Phase, ester is centrifugal in centrifuge, and glycerol is separated further.After separating glycerol, add the hot water of fatty acid wt 30%
Washing, separates hydrothermal solution and obtains washing thick ester, and the distillation cooling layering that the distillation of thick ester obtains, the upper strata obtained after separation is
No. six solvents, lower floor is methanol.Pumping into infuser after No. six solvent recovery to carry out leaching and carry oil, methanol pumps into ester reactor to be carried out
Esterification.Axe liquid is biodiesel oil product.The technical program meets (BD100) diesel fuel blending biomass
Diesel oil GB/T20828 method analysis detection Cetane number (CN) is not less than 49 percent, and sulfur content no more than (divide by quality
Number) 10 mg/kg, water content (mass fraction) is not more than percent zero point zero five, and total glycerol content (mass fraction) is no
More than percent point two, acid number (in terms of KOH) is not more than 0. 5 milligrams per gram, and sulfated ash (mass fraction) is no
More than percent point two, ester content (mass fraction) is not less than 96 five had point.
