Abstract
The present invention relates to preparation process of molybdenum containing oil soluble catalyst. The molybdenum containing oil soluble catalyst, molybdenum naphthenate is produced in a simple process with mild conditions, and the production process is suitable for use in industrial production. When molybdenum naphthenate is applied in producing oil with coal in the added amount of 1.0 %, the yield of oil may raised to over 60 %.
Description
The present invention relates to a kind of coal system oil catalyzer that metal molybdenum is main active ingredient that contains.
Because China's oil shortage of resources, for alleviating nervous this situation of oil supply, domestic many large-scale coal enterprise has begun to set foot in coal system oil field, in coal system oil process, crucial catalyzer is to contain the molybdenum organic compound, the molybdate compound of using in the past mostly is inorganics, cost an arm and a leg, and coal to change olefiant yield low.The research of domestic many enterprises, scientific research institutions' process recent two decades, find to use molybdenum naphthenate, coal to transform olefiant yield and greatly improve, but the existing production method of molybdenum naphthenate, do not satisfy the requirement of coal system oil tech, molybdenum content is low, synthesis technique complexity, product yield are not high, and all do not realize suitability for industrialized production.
The objective of the invention is to: take reasonable process technology, synthetic new catalyst with efficient catalytic ability.Make it in the reaction that coal system oil transforms, to promote yield to improve.
The present invention seeks to realize like this:
At first synthetic naphthenic acid diethanolamine ester reacts with molybdic acid under acidic conditions again, through extraction, the refining purpose product, brown or blue thick liquid molybdenum naphthenate of obtaining.
Its structural formula is:
Catalyzer-molybdenum naphthenate of the present invention is characterized in that molybdenum content is higher, and Mo% 〉=6 oil solubles are good, and is good with other catalyzer compatibleness, and concerted catalysis efficient height makes coal transform olefiant yield and significantly improves.
Elaborate in conjunction with the embodiments:
The preparation of l, naphthenic acid diethanolamine ester
In the there-necked flask that agitator, thermometer, vacuum extractor are housed, take by weighing 2.0mol naphthenic acid, 2.0mol diethanolamine, stir down and be warming up to 110 ℃ gradually, reacted 3.5 hours, reduce to normal temperature and make light yellow thick liquid, naphthenic acid diethanolamine ester.
2, synthetic molybdenum naphthenate
Take by weighing molybdic acid 1.0mol, water is dispersed into slip, add the 10ml vitriol oil, when naphthenic acid diethanolamine ester is warming up to 50 ℃ of left and right sides, add the molybdic acid aqueous dispersions, be warming up to 85 ℃ ± 1, react after 3 hours and heat up again, continue to react 3 hours to 130 ℃, reduce to then about 50 ℃, filtered while hot is removed solid impurity and is obtained the brown or blue thick liquid molybdenum naphthenate of purpose product.
It is molten to make purpose product molybdenum content be increased to Mo% 〉=6 oil by above-mentioned synthetic method, and the raising that coal is changed into oily yield has significant katalysis, and the key technical indexes of product is as follows:
Molybdenum naphthenate
| Project | Index | Analytical procedure |
| Outward appearance | Brown or blue thick liquid | Range estimation |
| Molybdenum content % | ≥6 | The n-butyl acetate extraction spectrophotometry |
| Moisture content % | ≤0.08 | GB/T 260 |
| Mechanical impurity % | ≤0.06 | GB/T 511 |
| Flash-point (opening) ℃ | Be not less than 150 | GB/T 3536 |
| Addition % | 1.0 |
Application experiment:
Produce in the technology of liquid fuel at hot melt catalysis coal, add 1.0% molybdenum naphthenate, coal transforms olefiant yield and brings up to more than 60% from original 29%, and katalysis is very obvious.
Claims (2)
1. catalysts containing molybdenum-molybdenum naphthenate is characterized in that by two step condensation reactions, under than the demulcent reaction conditions, is easy to synthetic this purpose product, adds 1% molybdenum naphthenate in coal system oil, can improve coal effectively and transform olefiant yield.
The molybdenum naphthenate structural formula is:
2. said according to claim 1, it is characterized in that adding when coal changes into oil 1% molybdenum naphthenate, can improve the yield of oil fuel.
