It is superfluous to there is domestic and international low side wax product in current phase-change wax industry, and the problem that high-end wax product is rare, and traditional phase-change wax preparation method is by being prepared from petroleum fractionating component, often there is complex process, cost is high, produces the problem that there is potential safety hazard.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, and technical problem to be solved is to provide the simple phase-change wax preparation method of a kind of technique, and the method can realize customized production as required, cuts the waste, reduces costs, effectively increase economic efficiency.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of phase-change wax preparation method, comprises following step: coal produces the synthetic raw gas (H obtained through gasification
2with the mixture of CO, hydrogen-carbon ratio is 1.5:1-2.0:1), at 220 DEG C, under 3.0MPa condition, unstripped gas enters paste state bed reactor, under the effect of Fe-series catalyst (IGC-IAR, Chinese Academy of Sciences's coalification developed), there is Fischer-Tropsch synthesis, obtain Fischer-Tropsch synthetic (comprising light ends oil, heavy distillate, pyroparaffine and other oxygenatedchemicals); At 8.0MPa, under 280-300 DEG C of condition, Fischer-Tropsch synthetic carries out hydrogenation reaction, and (required catalyzer is the ICR-154 that Chevron Corporation produces, the FF26 that Fushun petrochemical industry research institute produces or the KF-848 that Aksu company produces), obtain the mixture that cut is wider, i.e. Fischer Tropsch waxes; Fischer Tropsch waxes, under 0.5MPa, 230-280 DEG C of condition, carries out the short steaming rectifying of molecule, obtains the refining wax product of different phase transformation enthalpy; Add NNO, additives ratio is 10ppm/kg, obtains stable phase-change wax.The recovered temperature that different phase transformation enthalpy refines wax product is as shown in table 1 below:
The different phase transformation enthalpy of table 1 refines the recovered temperature of wax product
Compared with prior art the invention has the beneficial effects as follows:
1. the present invention adopts the technique of the short steaming rectifying of molecule to Fischer Tropsch waxes, compared with conventional pressure relief distil process: reduce costs, and shortened process; Because the Product Precision needed is high, adopt the short distil process of molecule more effective selectivity can steam specific product; In minimizing mixture, other impurity is to the pollution distilling out product; The temperature needed is low, reduces security risk.
2. the product phase transformation enthalpy that distillates of the present invention is classified, with traditional classify with fusing point compared with: directly produce product according to customer need for leading; Reduce and blindly produce, reduce costs; Be beneficial to subsequent production technique classification process.
3., by phase-change wax prepared by the preparation method of phase-change wax of the present invention, tool has the following advantages:
(1) can customized production as required, cut the waste, reduce costs;
(2) because domestic and international low side wax product is superfluous, and high-end wax product is rare, therefore has object to distill out related products, can more effectively increase economic efficiency;
(3) other derived prods can be obtained through follow-up more effective art breading, aromatic hydrocarbon product etc. as high in other economic worth to the mix product that other non-required distills out.
