Abstract
The invention provides the chemical technology of biological diesel oil transformed by grease, which includes the reaction of grease and the carbinol, the invention is characterized in that dehydrated gypsum (chemical name: calcium sulphate) powders are mixed in the carbinol to conduct esterification reaction with the grease, the water-containing gypsum crystallinesubstance is filtered and separated after the completion of reaction, the gypsum can positively absorb water in the mixture to keep the ninety nine percent purity of the carbinol solution, thus improving the yield and reaction speed of the carbinol, so the invention can be used in biological diesel oil production of a plurality of types of grease.
Description
Technical field
The present invention relates to a kind of catalyst, especially quicken the catalyst of the conversion biodiesel of grease.
Background technology
In the transformation technology of present grease, carry out ester exchange reaction, generate methyl esters and glycerine at grease and methyl alcohol; And in the esterification of aliphatic acid and methyl alcohol, the reaction of 1 moles of fatty acids and 1 mole, of methanol generates the water of 1 mole of methyl esters and 1 mole.The concentration of the water meeting diluting reaction thing methyl alcohol that generates like this, thus methanol output is reduced greatly, and slowed down reaction speed.Processing mode is exactly to adopt the method for removing aliphatic acid at present, can increase technological process and cost like this.
Summary of the invention
The invention provides and a kind ofly can simplify technology, and save the catalyst of cost.
For achieving the above object, technical scheme of the present invention is:
A kind of catalyst that quickens the conversion biodiesel of grease is characterized in that being mixed with potassium hydroxide, sodium methoxide, ferric trichloride and being formed by dehydration silica gel.
Moisture in the dehydration silica gel energy active absorption mixture makes methanol solution keep 99% purity, thereby improves methanol output and reaction speed like this; Potassium hydroxide, sodium methoxide can improve reaction speed; Ferric trichloride can directly precipitate removing glycerine.
The specific embodiment
In concrete the enforcement, can have the inorganic salts of the crystallization water with having added some in the silica gel, as cobalt salt.When anhydrous be exactly state when losing the crystallization water be blue look, the state when being exactly the crystallization water during suction is pink.Discolour silica gel can recycle.
In addition, the mixed proportion of potassium hydroxide, sodium methoxide, ferric trichloride is the catalyst of forming at 3: 3: 10.
Claims (3)
1. catalyst that quickens the conversion biodiesel of grease is characterized in that being mixed with potassium hydroxide, sodium methoxide, ferric trichloride by dehydration silica gel and forms.
2. according to claim 1, it is characterized in that having the inorganic salts of the crystallization water, as cobalt salt with having added some in the silica gel.When anhydrous be exactly state when losing the crystallization water be blue look, the state when being exactly the crystallization water during suction is pink.Discolour silica gel can recycle.
3. according to claim 1, the mixed proportion that it is characterized in that potassium hydroxide, sodium methoxide, ferric trichloride is the catalyst of forming at 3: 3: 10.
