example 1

[0017] First, weigh 30g of oily sludge from the oil refinery and pour it into a Erlenmeyer flask containing 80mL of culture medium. Incubate in a shaker at 35°C and 120r / min for 5 days. Then take 10mL of the resulting culture solution and pour it into a fresh 80mL flask. In an Erlenmeyer flask of culture medium, incubate in a shaker at 35°C and 120r / min for 5 days. Repeat this for 3 times. Centrifuge and discard the lower sediment. Take the supernatant to obtain the enriched culture solution. ; Then sequentially add 75g54# paraffin wax and 45g microcrystalline wax to the crucible, heat it to melt completely, and then add dropwise to the fermenter containing 80mL of the enriched culture solution obtained above while hot, during the dripping process, Turn on the fermenter agitator, set the speed to 1200r / min, when the dripping is completed, stop the stirring, heat to 35℃, keep the fermentation for 2 days, suction filter, remove the filtrate, and wash the filter cake 3 times with d...

[0023] First, weigh 45g of oily sludge from the refinery and pour it into an Erlenmeyer flask containing 100mL of culture medium. Incubate in a shaker at 40°C and 160r / min for 7 days, and then take 15mL of the obtained culture solution and pour it into a 100mL fresh In the Erlenmeyer flask of the culture medium, incubate in a shaker at 40°C and 160r / min for 7 days. Repeat this for 3 times. Centrifuge, discard the lower sediment, and take the supernatant to obtain the enriched culture solution. ; Then sequentially add 90g54# paraffin wax and 55g microcrystalline wax to the crucible, heat it to melt completely, and then add it dropwise while hot to the fermenter containing 100mL of the enriched culture solution obtained above. During the dropping process, Turn on the agitator of the fermenter, set the speed to 1400r / min, when the dripping is completed, stop stirring, heat to 40℃, keep the fermentation for 4 days, filter with suction, remove the filtrate, and wash the filter cake 5...

Abstract

The invention discloses a method for preparing controllable shallow oxidized paraffin and belongs to the technical field of oxidized paraffin preparation. Firstly, microorganisms in oil-containing sludge of an oil refinery are subjected to culture and enrichment to obtain a culture solution, then paraffin and microcrystalline wax are mixed and fused, the mixture is added dropwise and dispersed in the culture solution in the high-speed stirring state, mixing, fermentation and activation are conducted, toughness of raw material paraffin is improved so that paraffin can not crack easily, then washed wet powder is mixed with calcium oxide for drying, calcium hydroxide is generated and used for improving hardness of a product, then compressed air serves as weak oxidant under the catalytic condition of manganese stearate, and paraffin is oxidized to prepare the controllable shallow oxidized paraffin through injection molding and curing. The method has the advantages that the obtained product is good in toughness, hardness is as high as 6-10 H, mixing, fermentation and activation of the mixed paraffin and the culture solution are fully used, calcium oxide is added to improve toughness and hardness, pertinence is high, and the problem that breaking happens under the action of external force is effectively solved.

Description

Technical field [0001] The invention relates to a preparation method of controllable shallow oxidized paraffin, belonging to the technical field of oxidized paraffin preparation. Background technique [0002] The world's paraffin-based crude oil is mainly concentrated in Asia, and my country is the country with the most paraffin-based crude oil resources and production. Although my country's production of paraffin wax is large, the trading of domestic special wax products in the international market is still in its infancy, and the composition of paraffin wax varieties is unreasonable. Most special waxes and special wax products are only produced in small batches. [0003] The development of high value-added paraffin products and the improvement of the technical content of deep-processed paraffin products can further enhance the market competitiveness of paraffin products. Paraffin wax can be widely used in chemicals, medicine, food, transportation and other industries. my countr...
