Definitions
- the present invention relates to a catalytic thermal de- polymerization process of plastic waste materials. More particularly, relates to the use of a solid catalyst to convert plastic waste materials into high quality liquid fuels at a substantially low temperature without affecting yields thereof.
- waste plastics pyrolysis process has successfully alleviated limitations generally observed in fluidized bed process, for example, back mixing of pyrolysis products, non-uniformity of the fluidized bed, and more importantly low yield of valuable aromatic and high molecular hydrocarbons.
- this technology is relatively expensive since it is a multistep stage process and requires high temperature and high pressure conditions to completely decompose the plastic wastes into hydrocarbon oils.
- additional step such as removal of coke deposited on the fluidized bed by means of combustion at a temperature between 600°C and 900°C is required and thus contributes to a high maintenance cost.
- thermal catalytic de-polymerization process of plastic wastes to obtain its original monomers under a milder thermal condition is rather preferred than any pyrolysis methods in the art.
- An example of such thermal catalytic de-..polymerization process. . includes . U ..S . Patent Application No.
- a thermal de- polymerization process involves the use of limestone catalyst to catalytically enhance decomposition of waste plastic materials to their constituent monomers, which in turn are readily convertible into liquid transportation fuels at a temperature of below 460°C under normal atmospheric pressure condition, is provided.
- Said thermal de-polymerization process preferably comprising the steps of: providing waste plastic materials in molten form; de-polymerizing the molten waste plastic materials into a reaction chamber using a limestone catalyst at a temperature ranging from 420°C to 450°C range at normal atmospheric pressure condition of 1 Bar; and introducing gaseous de- polymerized products to a distillation unit thereby allows the de-polymerized products to be fractionally distilled and condensed into liquid transportation fuel. It .is.
- the limeston.e catalyst o.f the present invention is a sintered product resulted from a solid composition comprising aluminum oxide (A1 2 0 3 ) ranging from 39% to 41%; calcium oxide (CaO) ranging from 30% to 32%; silicone oxide (SiO) ranging from 0.09% to .0.-12%; and magnesium oxide ranging from 0.01% to 0.03%.
- Figure 1 is a flow chart illustrating the thermal de- polymerisation process of waste plastic materials so as to obtain liquid hydrocarbons therefrom, particularly transportation fuels in details. '
- the .present ..invention relates to a proce.ss (100) for. thermal depolymerization of waste materials, particularly plastic waste materials (10), into liquid transportation fuel (15) with the use of limestone (20) as a catalyst.
- the wasteplastic materials (10) as described herein referred to municipal and/or industrial wastes made of, include but not limited to, polyethylene, polypropylene and polyvinyl chloride.
- the limestone catalyst (20) is resulted by means of sintering a solid composition comprising aluminum oxide (AI2O3) ranging from 39% to 41%; calcium oxide (CaO) ranging from 30% to 32%; silicone oxide (SiO) ranging from 0.09% to 0.12%; and magnesium oxide ranging from 0.01% to 0.03%. More preferred the solid composition comprises 40.6% ⁇ 0.1 aluminum oxide (AI2O3) ; 31.7% ⁇ 0.1 calcium oxide (CaO); 0.15% ⁇ 0.01 silicone oxide (SiO); and 0.03 ⁇ 0.01 magnesium oxide (MgO) .
- AI2O3 aluminum oxide
- CaO calcium oxide
- SiO silicone oxide
- MgO magnesium oxide
- such limestone catalyst (20) allows plastic waste materials to be totally depolymerized into higher olefins (C4-C25) at a low temperature, preferably at temperature of below 460° under normal atmospheric pressure condition of 1 Bar.
- carbonization process which leads to formation of decomposed residues or coke crystals and unacceptable environmental hazards, for example, greenhouse gases, dioxins and furans, can be suppressed with such substantially low operating temperature.
- Thermal depolymerization of plastic waste materials alongside with said limestone catalysts therefore, has undoubtedly rendered the technology more economically viable and environmentally acceptable .
- Figure 1 provides the thermal depolymerization process of plastic waste materials (10) into valuable chemicals, particularly liquid transportation fuels (20) in details.
- Said method involves the step of depolymerizing (S103) a molten form of plastic waste materials (10) in a reaction chamber having a limestone catalyst (15) of the present invention included therein, at a temperature ranging 420°C to 450° under normal atmospheric pressure condition of 1 Bar.
- the molten plastic waste materials (10) can be prepared by heating (S101) solid plastic wastes (10) at a temperature of below 250°C in a heated chamber.
- the solid plastic wastes (10) may be , shredded and water content thereof is eliminated prior to being subjected to a hot melt extruder (S101) .
- solid composition a solid composition comprising aluminum oxide (AI2O3) ranging from 39% to 41%; calcium oxide (CaO) ranging from 30% to 32%; silicone oxide (Si.O) ranging from 0.09% ⁇ to 0.12%; and. magnesium oxide ranging from 0.01% to 0.03%.
- solid composition comprises 40.6% ⁇ 0.1 aluminum oxide (AI2O3) ; 31.7% ⁇ 0.1 calcium oxide (CaO); 0.15% ⁇ 0.01 silicone oxide (SiO); and 0.0310.01 magnesium oxide (MgO) is pulverized and sintered (S102) to form the limestone catalyst (15) of present invention.
- the depolymerization products (25), preferably a mixture of gaseous hydrocarbons, are then subjected to a distillation unit whereby allows the gaseous hydrocarbons (25) to be fractionally distilled and condensed (S106) into liquid transportation fuels (20) such as fuel diesel, kerosene and gasoline.
- the mixture of gaseous hydrocarbons (25) is preferably fractured (S104) at temperature ranging from 420°C to 450 °C under normal atmospheric pressure condition of 1 Bar before the distillation process (S106) .
- a cleaning step (S105) to eliminate aerosols and particles carried by the .depolymerized. hydrocarbons .(2.5) is . provided.
- Said cleaning step (S105) preferably includes the step of guiding depolymerized hydrocarbons (25) into a pressure secure container through a high speed cyclone, thereby removing undesirable substances thereof prior to- being distilled.
- the depolymerization process (100) of the present invention not only can decompose plastic-derived waste ⁇ materials (10) at a temperature ranging 420°C to 450°C with a cost-effective catalyst, but high quality motor vehicle fuels (20) having a cetane number of above 55 and sulfur PPM of between 0 and 50 have also been successfully recovered from waste plastic materials (10) .
