Abstract
A carried alkali-metal catalyst for synthesizing biologic diesel oil by exchange reaction of the fatty-acid ester is prepared from alkali-metal salt (LiNO3, NaNO3, or KNO3) or alkali-metal hydroxide (LiOH, NaOH, or KOH) and alkali-earth metal oxide (Cao, SrO, or BaO) through preparing the salt (or alkali)-soluble aqueous solution of alkali-metal salt (or hydroxide), immersing alkali-earth metal oxide in it, ageing, evaporating solvent, baking and grinding.
Description
Technical field
The present invention relates to a kind of catalyst, especially relate to a kind of solid base catalyst that can carry out the ester exchange reaction biodiesel synthesis at the following catalysis fatty glyceride of methyl alcohol boiling point and methyl alcohol.
Background technology
Adopt the biomass materials such as soybean oil, rapeseed oil, rice bran oil, the former oil expression of transgenosis oil plant crop, catering trade waste grease and industrial oil foot of wide material sources, carry out the fatty acid methyl ester that ester exchange reaction prepares with methyl alcohol, as the substitute fuel of mineral diesel, advantage such as have that power performance is good, safe in utilization, the pollutant emission index is low and resource is renewable.With respect to the acid catalysis system, the base-catalyzed transesterification reaction has the high and alcohol ester advantage lower than requiring of reaction specific activity, but in the technology with liquid base catalyzed transesterifications such as NaOH, sodium methoxides, the washing separation and purification link of complex steps has still increased running cost and Environmental costs inevitably; And in production of biodiesel with lipase-catalyzed esterification, existing reaction efficiency is low, catalyst costs an arm and a leg and methyl alcohol to enzyme catalyst poison problem such as effect, also limited the competitiveness of this method on practicability is promoted.By liquid base is carried out the immobilization transformation, can keep under the prerequisite of high activity of catalyst, simplify process procedure, (Min Enze, Chinese engineering science, 2005,7 (4): 1-4) reduce production costs.
In existing solid base type ester exchange catalyst design; the general base strength of all emphasizing load alkali center; and the ignorance metal ion is to the polarization activation of carbonyl; make and descend through the acyl acceptor of alkali center activation formation and the reaction efficiency of carbonyl carbon; under same transesterification conditions, the formation speed of fatty acid methyl ester will be subjected to restriction (Li Weimin, the chemical industry journal of this step; 2005,56 (4): 711-716).Because the restriction of acidylate speed, reaction needed obviously can cause adverse effect to equipment and production efficiency by improving the yield that temperature or time expand guarantee the biodiesel product.Mentioned solid base from the patent application (CN 200510037862.2) of disclosed solid base ester exchange catalyst; the activation of acyl group is only considered to utilize its alkalescence; adopted the strong but bigger alkali metal rubidium of radius of alkalescence; and also introduce the polarization center be complementary on the carrier, so catalytic performance can only rely on the highly basic center after the activation to guarantee.Yet ester exchange reaction will cause the forfeiture gradually of catalytic activity to its continuous passivation, shortens catalyst service life, and then influences the catalyst reuse.
Summary of the invention
Purpose of the present invention is intended at above-mentioned problems of the prior art, provide a kind of can be under the reaction condition of gentleness, promote the exchange reaction of fatty acid ester efficiently to carry out, and technology is simple, the synthesis reaction catalyst for loading type alkali metal biodiesel oil that cost is low.
The composition of synthesis reaction catalyst for loading type alkali metal biodiesel oil of the present invention comprises alkali metal salt and alkaline earth oxide, or alkali metal hydroxide and alkaline earth oxide, the content of alkali metal salt or alkali metal hydroxide is 5%～40% of catalyst total amount by mass percentage, the content of alkaline earth oxide is 60%～95% of catalyst total amount, described alkali metal is Li, Na, at least a among the K; Described alkaline earth oxide is CaO, SrO, and at least a among the BaO, described alkali metal salt is LiNO
3, NaNO
3, KNO
3In at least a, described alkali metal hydroxide is LiOH, NaOH, at least a among the KOH.
The preparation method of synthesis reaction catalyst for loading type alkali metal biodiesel oil of the present invention is as follows:
The alkaline earth oxide carrier is immersed in the aqueous solution of alkali-soluble salt or solvable alkali by catalyst proportion, flood minimum 0.5h through stirring ageing, after being preferably 0.5～10h, the heating solvent evaporated, powder aggregates after the poly-powder oven dry of gained is ground less than 100 purpose powder, obtain synthesis reaction catalyst for loading type alkali metal biodiesel oil.The temperature of oven dry is 80～200 ℃, is preferably 90～120 ℃.
It is 3: 1～50: 1 material system that the ester exchange active testing has adopted methyl alcohol/vegetable oil mol ratio, in weight be the solid base catalyst of reactant 1%～5% in the mode that suspends at 1 atmospheric pressure, under 63 ± 2 ℃ the condition, reaction 0.5～6h, obtain product, form through the gas chromatographic analysis mixture, calculate the yield of fatty acid methyl ester.For preventing solid base catalyst because of surperficial saponification inactivation, reaction uses the acid value of feedstock oil must be controlled under the level of 3mg/g, as uses the higher waste grease of acid value to be raw material, need carry out depickling to raw material before reaction and handle.
The present invention introduces the basic supports surface with charge density higher alkali metal ion, promote two consecutive steps in the catalytic reaction simultaneously, realize quickening the purpose of ester exchange reaction, improve the ester exchange activity of solid base catalyst, this solid base catalyst can be under the reaction condition of gentleness (pressure＜0.5MPa, temperature＜80 ℃, acid value＜3mg KOH/g), promote the exchange reaction of fatty acid ester efficiently to carry out, make the production of biodiesel efficient of solid base catalyst near liquid bases such as sodium methoxides.Ester exchange rate reaches about 90% (part catalyst ester interchange conversion rate reaches 99%), and product obtains satisfying 0 after separating purification
#The fatty acid methyl ester of diesel oil main performance index, and by-product glycerol.And with the solid base particle of heterogeneous forms participation reaction, simple and easy to do with separating of biodiesel product, postprocessing working procedures obtains simplifying, and catalyst is also reusable, has reduced the running cost and the Environmental costs of production of biodiesel.
