Abstract
The invention provides a PET polyethylene terephthalate material degradation catalyst, the catalyst is a load type ramie stick carbon based catalyst, the catalyst uses ramie stick carbon as a main raw material, and after basic load processing in a fluoride and sodium sulfate solution, the catalyst is prepared. The invention discloses the PET polyethylene terephthalate material degradation catalyst, the PET polyethylene terephthalate material degradation catalyst is reasonable in component configuration, can be prepared by making full use of biomass wastes, and is simple in process and low in cost, the prepared catalyst not only saves resource effectively, but also has a significant effect on the degradation of PET, and realizes the resource reuse.
Description
Technical field
The present invention relates to a kind of catalyst of PET material, particularly relate to a kind of PET material degraded catalyst, belong to plastic material technical field.
Background technology
Polyethylene terephtalate is a kind of important engineering plastics, it has excellent physical and mechanical properties in wider temperature range, under high-temperature high-frequency, still can keep excellent electrical insulation capability, be widely used in the every profession and trades such as electronics, food, medicine, office appliance, toy by the PET sheet that it is produced.But PET is very slow at occurring in nature degradation speed, to environment, therefore needs to carry out recycle and reuse to PET, to reduce environmental pollution, realizes the recycling of resource.
In current art, for solving the pollution of waste PET material, generally recycling PET by physics, biology and chemical recovering method, by ethylene glycol and catalyst degraded PET, reclaiming ethylene glycol terephthalate monomer, realizing resource reutilization.At present, the catalyst that degraded PET selects adopts chemical raw material to be prepared mostly, although have good degradation effect, compare power consumption, cost is high again, and the economic worth of performance is limited.Therefore, developing a kind of biomass castoff that adopts is new catalyst prepared by primary raw material, can reduce environmental pollution, saving resource, can turn waste into wealth again, meet the requirement of sustainable development.
Summary of the invention
For the demand, the invention provides a kind of PET material degraded catalyst, this catalyst makes full use of biomass castoff and is prepared, preparation technology is simple, with low cost, obtained catalyst has not only effectively saved resource, and to PET, there is significant degradation effect, achieve resource reutilization.
The present invention is a kind of PET material degraded catalyst, this catalyst is support type ramie boon carbon-supported catalysts, described catalyst is with ramie boon carbon for primary raw material, shaping by preparing after the alkaline load process carried out in potassium fluoride and metabisulfite solution.
In a preferred embodiment of the present invention, described ramie boon carbon is powdered granule, and its average particulate diameter is about 15-18um.
In a preferred embodiment of the present invention, the concentration of described potassium fluoride solution is 10%, and the mass ratio of it and ramie boon carbon is 3:1.
In a preferred embodiment of the present invention, the concentration of described metabisulfite solution is 15%, and the mass ratio of it and ramie boon carbon is 5:1.
Present invention is disclosed a kind of PET material degraded catalyst, the configuration of this catalyst component rationally, biomass castoff can be made full use of be prepared, simple process, with low cost, obtained catalyst has not only effectively saved resource, and to PET, there is significant degradation effect, achieve resource reutilization.
Detailed description of the invention
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
In the PET material degraded catalyst that the present invention mentions, this catalyst is support type ramie boon carbon-supported catalysts, described catalyst is with ramie boon carbon for primary raw material, shaping by preparing after the alkaline load process carried out in potassium fluoride and metabisulfite solution.
Further illustrate, this catalyst for primary raw material with ramie boon discarded in a large number, is prepared ramie boon carbon by pyrolysis, and is carried out alkaline load to it, and then it is catalyst based to prepare biomass carbon, and be applied to the ethylene glycol catalytic degradation reaction of PET material.Wherein, ramie boon is the major part in ramie, and it accounts for about 90% of whole ramie weight, and it is made up of cellulose, hemicellulose, lignin and pectin etc.As a kind of biomass castoff, current ramie boon is not utilized effectively, and both contaminated environment, waste resource again; Ramie boon resource is fully utilized, turns waste into wealth, played the economic worth that it is maximum.Introduce two kinds of alkaline solutions during this catalyst preparing and carry out alkaline load-reaction, wherein, the concentration of potassium fluoride solution is 10%, and the mass ratio of itself and ramie boon carbon is 3:1; The concentration of metabisulfite solution is 15%, and the mass ratio of itself and ramie boon carbon is 5:1; Ramie boon carbon is powdered granule, and its average particulate diameter is about 15-18um.
The present invention is applied to the ethylene glycol catalytic degradation reaction of PET material usually, and it can reach 100% to the degradation rate of PET.To in the actual degradation process of PET material, be first the sodium hydroxide solution immersion treatment PET material section 2h of 10% by mass concentration, then washes clean post-drying that PET material is cut into slices; Then get a certain amount of support type ramie core carbon-supported catalysts, ethylene glycol solvent, and catalyst, ethylene glycol solvent and PET are placed in reactor, stirring reaction 3h at 200 DEG C; Finally be cooled to room temperature, and reclaim filtrate steam remove after obtain ethylene glycol terephthalate monomer.
Present invention is disclosed a kind of PET material degraded catalyst, the configuration of this catalyst component rationally, biomass castoff can be made full use of be prepared, simple process, with low cost, obtained catalyst has not only effectively saved resource, and to PET, there is significant degradation effect, achieve resource reutilization.
The above; be only the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention; the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
