Abstract
The utility model relates to a 1,4-cyclohexanedicarboxylates continuous fixed bed reactor which has the innovative characteristics that a first-order reactor and a second-order reactor, connected in series, are included; a material inlet is formed in the top end of the first-order reactor; a material outlet is formed in the bottom end of the second-order reactor; and the first-order reactor and the second-order reactor are tube type fixed bed reactors. Material, namely dimethyl terephthalate, is subjected to ring hydrogenation continuously through tube-type fixed bed reactors connected in series, the material conversion rate reaches more than 98%, and is improved by 1 to 2% as compared with the traditional independent fixed bed reactor, and in addition, the service life of a catalyst is prolonged to be more than one year.
Description
Technical field
The utility model relates to a kind of fixed bed reactors, particularly a kind of Isosorbide-5-Nitrae-cyclohexane diacid dimethyl ester serialization fixed bed reactors.
Background technology
1,4-CHDM is saturated polyester and the synthetic intermediate of unsaturated polyester (UP) of coating, printing ink, adhesive, insulating materials and some specific use aspects.Have very high vitrification point by its goods that produce, have good hardness and certain pliability is arranged, the gained light-colored resin has good heat endurance and preferably dissolubility and against weather is arranged.For the manufacture of polyester fiber, polyester electrical appliance, unsaturated polyester resin, polyester glaze, polyurethane foam plastics, and for the production of lubricant and hydraulic fluid.
In the process of the synthetic 1,4-CHDM of dimethyl terephthalate (DMT) two-step catalysis hydrogenation, at first need dimethyl terephthalate (DMT) ring Hydrogenation is got Isosorbide-5-Nitrae-cyclohexane diacid dimethyl ester.Traditional Isosorbide-5-Nitrae-cyclohexane diacid dimethyl ester reactor adopts independently fixed bed reactors, and it utilizes catalyst to encircle hydrogenation reaction and makes.The shortcoming of this kind fixed bed reactors is: conversion ratio is lower, and the life-span of benefiting from of catalyst only has 4 to 6 months.
Summary of the invention
But the technical problems to be solved in the utility model provides the high and extending catalyst of a kind of conversion ratio one prismane dimethyl ester serialization fixed bed reactors in service life.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of 1,4-cyclohexane diacid dimethyl ester serialization fixed bed reactors, its innovative point is: comprise A reactor and second reactor that series connection arranges, the top of described A reactor arranges material inlet, and the bottom of second reactor arranges material outlet; Described one-level, second reactor are calandria type fixed bed reactor.
The utility model has the advantage of: the material dimethyl terephthalate (DMT) encircles hydrogenation by the calandria type fixed bed reactor of profit series connection continuously, materials conversion rate reaches more than 98%, intersect traditional independent fixed bed reactors and improve 1-2%, in addition, prolonged the service life of catalyst, reached more than 1 year.
Description of drawings
Fig. 1 is Isosorbide-5-Nitrae in the utility model-cyclohexane diacid dimethyl ester serialization fixed bed reactors structural representation.
The specific embodiment
As shown in Figure 1, comprise A reactor 1, second reactor 2, material inlet 3 and material outlet 4.
Above-mentioned A reactor 1 and second reactor 2 series connection arrange, and A reactor 1 bottom discharging opening is communicated with second reactor 2 top charging apertures, on the top of A reactor 1 material inlet 3 is set, and the bottom of second reactor 2 arranges material outlet 4.
A reactor 1 and second reactor 2 all adopt calandria type fixed bed reactor, and catalyst adopts alundum (Al2O3) as the metal palladium catalyst of carrier.
