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 the grease manufacture field, these two technology of the thick sour hydrogenation of plam oil hydrolysis hydrogenation and hydrolysis have been the technology of comparative maturity at present, but be present technological gap with the mixture of the thick acid of plam oil and the hydrolysis repeated hydrogenation that is hydrolyzed, almost do not have the research record of this respect.
Summary of the invention
The objective of the invention is to overcome in the grease manufacture field technological gap that plam oil hydrolysis hydrogenation and the thick sour hydrogenation of hydrolysis are existed, provide a kind of plam oil and hydrolysis thick acid hydrolysis hydrogenation technique.
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 material equivalent, and described raw material is mass percent, the reaction that in reactor, is hydrolyzed, and hydrolysis temperature is 260 ℃, hydrolysis time 4 hours, pressure is 3.8MPa ~ 4.6MPa in the hydrolytic process;
2) hydrolyzate washing: hydrolysate is washed, removed the glycerine that hydrolysis produces, carry out vacuum hydro-extraction after the washing again, design temperature is 140 ℃, vacuumizes with vacuum pump, and the time is 1 hour;
3) hydrolyzate hydrogenation: to the hydrolysate hydrogenation after the washing, hydrogen pressure is 1.8MPa, the initial setting temperature is 210 ℃, hydrogenation reaction is thermopositive reaction, and temperature can rise to 250 ℃ in the reaction process, react the violent phase later temperature can descend to some extent, in temperature decline process, temperature is set at 230 ℃, keeps higher hydrogenation reaction temperature, hydrogenation time kept 3 hours.
The present invention compared with prior art has following beneficial effect:
1. technology 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 in reactor, is hydrolyzed, hydrolysis temperature is 260 ℃, hydrolysis time 4 hours, pressure is 3.8MPa ~ 4.6MPa in the hydrolytic process;
2, hydrolysate is washed, removed the glycerine that hydrolysis produces, carry out vacuum hydro-extraction after the washing again, design temperature is 140 ℃, vacuumizes with vacuum pump, and the time is about 1 hour, (in the vacuum hydro-extraction process, temperature can rise to about 180 ℃);
3, hydrolysate hydrogenation, hydrogen pressure is 1.8MPa, the initial setting temperature is 210 ℃, hydrogenation reaction is thermopositive reaction, and temperature can rise to about 250 ℃ in the reaction process, react the violent phase later temperature can descend to some extent, in temperature decline process, temperature is set at 230 ℃, keeps higher hydrogenation reaction temperature, hydrogenation time kept 3 hours.
