Abstract
The invention discloses a hydrolysis and hydrogenation process of palm oil and hydrolyzed crude acid. The process comprises the following steps of: performing a hydrolysis reaction between 75 percent of palm oil and 25 percent of crude acid in a reaction kettle with water in the same weight as the raw materials, washing a hydrolysis product and dehydrolyzing in vacuum; and hydrogenating the washed hydrolysis product for 3 hours. The process has the advantages of reasonable and effective process, good effect, low cost and the like.
Description
Technical field
The present invention relates to a kind of plam oil and the thick acid hydrolysis hydrogenation technique of hydrolysis of grease manufacture field.
Background technology
At grease manufacture field, Hydrolysis of Palm Oil hydrogenation and these two technology of the thick sour hydrogenation of hydrolysis have been the technique of comparative maturity at present, but be current technological gap by the mixture of plam oil and the thick acid of the hydrolysis repeated hydrogenation that is hydrolyzed, almost do not have the research of this respect to record.
Summary of the invention
The object of the invention is to overcome in grease manufacture field Hydrolysis of Palm Oil hydrogenation and be hydrolyzed the technological gap that thick sour hydrogenation exists, a kind of plam oil and the thick acid hydrolysis hydrogenation technique of hydrolysis are provided.
The present invention realizes by following process program:
Processing step is as follows:
1) hydrolysis reaction: plam oil 75% and thick acid 25% add the water of above-mentioned raw materials equivalent, and described raw material is mass percent, the reaction that is hydrolyzed in reactor, hydrolysis temperature is 260 DEG C, hydrolysis time 4 hours, in hydrolytic process, pressure is 3.8MPa ~ 4.6MPa;
2) hydrolyzate washing: hydrolysate is washed, removed the glycerine that hydrolysis produces, carry out vacuum hydro-extraction after washing again, design temperature is 140 DEG C, vacuumizes with vacuum pump, and the time is 1 hour;
3) hydrolyzate hydrogenation: to the hydrolysate hydrogenation after washing, hydrogen pressure is 1.8MPa, initial setting temperature is 210 DEG C, hydrogenation reaction is thermopositive reaction, and in reaction process, temperature can rise to 250 DEG C, react the violent phase later temperature can decline to some extent, in temperature decline process, be 230 DEG C by Temperature Setting, keep higher hydrogenation reaction temperature, hydrogenation time keeps 3 hours.
The present invention compared with prior art has following beneficial effect:
1. technique is rationally effective;
2. effective cost is low.
Embodiment
Below by specific implementation process, content of the present invention is further described:
Implementation step:
1. the water of plam oil (75%)+thick acid (25%)+equivalent, the reaction that is hydrolyzed in reactor, hydrolysis temperature is 260 DEG C, hydrolysis time 4 hours, in hydrolytic process, pressure is 3.8MPa ~ 4.6MPa;
2, hydrolysate is washed, removed the glycerine that hydrolysis produces, carry out vacuum hydro-extraction after washing again, design temperature is 140 DEG C, vacuumizes with vacuum pump, and the time is about 1 hour, (in vacuum hydro-extraction process, temperature can rise to 180 DEG C of left and right);
3, hydrolysate hydrogenation, hydrogen pressure is 1.8MPa, initial setting temperature is 210 DEG C, hydrogenation reaction is thermopositive reaction, and in reaction process, temperature can rise to 250 DEG C of left and right, react the violent phase later temperature can decline to some extent, in temperature decline process, be 230 DEG C by Temperature Setting, keep higher hydrogenation reaction temperature, hydrogenation time keeps 3 hours.
