Abstract
The invention provides a method of disposing the free fatty acids from oil and fat, it includes the separation, precipitation or conversion of fatty acid. Adjunct consisting of catalyst and dehydrated calcium sulfate powder is put into the solution which includes oil and ethyl alcohol. The oil contains free fatty acids, and the temperature of catalyst is higher than the boiling point of water. After the reaction finished, distilling the catalyst and recover it. Thus, dehydrated calcium sulfate could absorb water of the mixture positively, and makes it lower water amount, while the recovery of catalyst is economical.
Description
Technical field
The present invention relates to a kind of biodiesel technology, the chemical industry method of especially greasy conversion biodiesel.
Background technology
In the present greasy transformation technology, carry out in the transesterification reaction at grease and methyl alcohol, 1 mole of grease and 3 mole, of methanol are reacted, and generate 3 moles of methyl esters and 1 mole of glycerin; And in the esterification of lipid 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 lipid acid at present, can increase technical process and cost like this.
Summary of the invention
The invention provides the simplification technology that a kind of grease transforms, and save cost.
For achieving the above object, technical scheme of the present invention is:
A kind of chemical industry method of greasy conversion biodiesel comprises the reaction of grease and methyl alcohol, it is characterized in that adding Bibulous Silica Gel and methyl acetate catalyzer in grease liquid, methanol liquid slowly is added in the mixing liquid reacts then.
Moisture in the Bibulous Silica Gel active absorption mixture makes methanol solution keep 99% purity, thereby improves methyl esters output and speed of response.
Embodiment
In concrete the enforcement, can have the inorganic salts of crystal water with having added some in the silica gel, as cobalt salt.When anhydrous be exactly state when losing crystal water be blue look, the state when being exactly crystal water during suction is pink.Discolour silica gel can recycle.After colour-change, can in loft drier, toast, make it get back to anhydrous state and just can continue to have used.
Secondly, grease, methyl alcohol, Bibulous Silica Gel and methyl acetate mixture ratio ratio are 12: 2: 1.
Claims (3)
1. the chemical industry method of a greasy conversion biodiesel comprises the reaction of grease and methyl alcohol, it is characterized in that adding Bibulous Silica Gel and methyl acetate catalyzer in grease liquid, methanol liquid slowly is added in the mixing liquid reacts then.
2. according to claim 1, it is characterized in that having the inorganic salts of crystal water with having added some in the silica gel.
3. according to claim 1, it is characterized in that grease, methyl alcohol, Bibulous Silica Gel and methyl acetate mixture ratio ratio are 12: 2: 1.
