Description

CATALYST FOR THERMOCATALYTIC CONVERSION OF PLASTICS WASTES AND METHOD OF MANUFACTURING THE SAME
Field of the invention.
The present invention concerns a catalyst, particularly for thermocatalytic conversion of polyolefin plastics wastes such as, for example, polyethylene or polypropylene. Advanageous application of the present catalyst comprises a continuous process of catalytic cracking of plastified and liquefied plastics wastes, even highly contaminated polyolefinic plastics wastes, to the form of liquid mixture of non-saturated and saturated hydrocarbons , constituting the high quality paraffin. The present invention relates also to a method of manufacturing of the present catalyst.
Background of the invention.
The American patent US 4,215,015 (TU HOSHENG) disloses a catalyst constituting a zeolitic crystalic aluminosilicate compound dispersed in amorphous matrix made of silicates and alurninium oxides, specifically for catalytic cracking of hydrocarbon charge. A method of its manufacturing comprises addition of crystalic aluminosilicate to gel containing an organic polymer together with silicates and aluminium oxides and subsequent spray-drying the gel in the temperature of its decomposition.
The Polish patent application P 336,773 teaches the application of the waste catalysts from fluidal catalytic cracking or natural aluminosilicates for catalytic cracking of plastics wastes.
The Polish patent application P 313,217 teaches also catalysts and carriers of catalysts obtained by means of press forming, in the form of granules having predetermined geometrical shape.
Additionally the Polish patent application P 321,062 presents a method of manufacturing hydrogenation catalyst basing on aluminium and transition metal alloy, in which, from the alloy and the auxilliary means, the kneaded mass is manufactured and the profiles are formed, roasted and treated with alkali metal hydroxide.
Besides the above, the Polish patent PL 85,689 presents a method of covering metal surfaces with catalyst, in which a cleaned metal surface is covered first with a layer of the hot plasma sprayed ceramic carrier and then the layer of carrier, partially melted with the metal, is covered or impregnated with a catalyst.
Also the Polish patent PL 87,626 teaches a method of manufacturing a stable aluminium oxide, as a catalyst carrier, out of aluminium hydroxide stabilized thermally with barium ions.
In addition, the Polish patent PL 58,082 teaches a method of placing profiles, in the form of solid bodies, spheres, pellets or rings, acting as a catalyst, in a permanent position on carrying elements fixed to pipe walls of chemical devicer l Known catalysts which are used specifically for catalytic cracking comprise mainly ceramic, in particular zeolitic, catalysts. They are characterised by poor thermal conduction, which causes difficulties at the initial stage of cracking of plastified and liquefied plastics wastes. They require special processes to place them on metal surfaces of cracking devices. They are quickly consumed. They are not suitable for hydrogen-free catalytic cracking of plastics wastes carried out at atmospheric pressure. Known methods of manufacturing of catalysts for catalytic cracking comprise complicated and costly multi-stage manufacturing of ceramic carrier later covered or impregnated with a catalyst. The hot plasma spraying requires costly devices for argon plasma spraying with argon-shielded internal arc. Besides, known methods for catalytic profiles placing concern only pipe conduits and known catalytic profiles have got small active surface.
It is the aim of the present invention to provide a catalyst, particularly for continous, hydrogen- free, thermocatalytic conversion of plastified polyolefin plastics wastes carried out at atmospheric pressure, without the above mentioned drawbacks.
It is also the aim of the present invention to provide a catalyst characerised by high porosity and good thermal conduction, in the form suitable for various stages of this industrial process.
It is also the aim of the present invention to provide a simple, easy and cheap method of manufacturing of the present catalyst preventing the installations corrosion and at the same time protecting against uncontrolled reactions during the melting and bringing the melted wastes to the predetermined depolymerisation temperature, and particularly against their carbonization.
The summary of the invention
These objects are achieved by a catalyst, particularly for thermocatalytic conversion of polyolefin plastics wastes with the participation of passivated aluminium, as expressed in claim 1, characterized in that it comprises a spongy bed built of aluminium microgranules surface covered with aluminium oxides, having multilayer bonded structure.
A method of manufacturing of a catalyst, particularly for thermocatalytic conversion of polyolefin plastics wastes, in which melted aluminium is sprayed, as expressed in claim 12, is accordingly to the present invention characterized in that it comprises spraying onto the base surface a spongy bed built of aluminium microgranules surface covered with aluminium oxides, having multilayer bonded structure.
Advantageous features have been presented in the sub claims 2-11 and 13-27 accordingly dependent on independent claims 1 and 12.
Brief description of the drawings
The present invention will be described in detail in advantageous embodiments with reference to the attached diagrammatic drawings, where Fig.l illustrates manufacturing of the catalyst bed, Fig.2 shows the microstructure of the catalyst bed, Fig.3 shows the base surface after shot blasting and Fig. 4 shows an axonometric view of the box container.
Detailed description of the invention
Fig.l illustrates diagrammatically the general scheme for the manufacturing of the present catalyst. This method comprises spraying the bed , built of aluminium microgranules 2 surface covered with aluminium oxides 2a, having multilayer bonded structure. This structure can be better seen in the Fig.2, which diagrammatically present the bed fragment indicated as A in the -Fig.l. A method of manufacturing the present catalyst consists generally in placing on the base 3 aluminium introduced into the spraying device 7, for example in the form of an oxy-acetylene blowpipe, wherein aluminium could be introduced in the form of a pure aluniinium wire 10, which is melted in the blowpipe flame 8 at temperature about 2800°C. Sprayed aluminium is placed onto the base surface in 3 to 5 layers, usually in four layers so, that microgranules have an average diameter 2-30 μm, advantageously about 10 μm. Microgranules 2 can be sprayed in the oxygen enriched atmosphere, to obtain faster oxidizing of their surface and as the spraying device 7 one can also use a metal spraying pistol. A spraying beam 9 should be highly uniform.
Depending on the destination, i.e. the place and the way of using the catalyst, the bed I is obtained differently, particularly in relation to the surface preparation of the base 3 and the final stages of the catalyst preparation (after the bed 1 has been sprayed).
In the present invention the bed I has been realized in two different advantageous embodiments. In the the first embodiment the bed 1 is permanently spreaded onto the surface 11 of the base 3, as seen on Fig.3, prepared by means of compressed air shot blasting. Before the shot blasting treatment all traces of corrosion are removed. Then the shot blasting treatment is carried on until the surface roughness 80 to lOOA is achieved. Later the surface 11 is washed with an organic solvent (toluene, xylene and carbon tetrachloride were used) to remove dust, damp and grease. Just before spraying the surface ϋ of the base 3 is heated to the temp. 350 to 400°C. Permanently spreaded, the bed i, with the thickness 0.2 to 0.6 mm, advantageously
0.4mm, is applied on internal surfaces of all devices taking active part in the process of thermocatalytic conversion of polyolefin plastics wastes.
According to the second embodiment of the present invention, the bed 1 is used without the base i.e. it is lifted off the base 3 after it has been formed by spraying. In the discussed embodiment, the base 3 , in the form of 3mm OH 18N9 (heat-resistant steel) metal sheet with dimensions 1000x1000mm, has been covered with one layer of anty-adhesive separator before spraying. Then the stabilized surface jj. of the base 3 was sprayed with three layers of A1/A12 O3j wherein it was cooled after having been sprayed with each layer, until the total thickness of the bed i reached about 0.4mm. The obtained sheet of the bed 1 has been then lifted off the base 3 and cut into strips 4 about 20mm wide, by means of a rotary cutter. The strips 4, with the length of about 500mm and the thickness of the bed I, i.e. about 0.4mm, are then spirally coiled and arranged in a box container 5, advanageously with dimensions 400x1 OOx 20mm, as shown on Fig.4, so that the axes of the coils were perpendicular to the openwork covers 6.
The obtained sheet of the bed 1 could be also crushed into pieces with the maximum dimension smaller than 10mm, which are added to the charge in the quantity of 1-2 % by weight. - The present catalyst, after its recovery from the waste product is regenerated by means of roasting it in temperatures between 500°C -660°C, advantageously below 600°C, and recycled. The regenerating increases the catalytic ability of the present catalyst.
