Coking Chamber / Section : Made up of Stainless Steel or Mild Steel or Combination of them. Thickness of the material is in proportion of size of the Coker and to withstand the heavy temperature Shape: Cylindrical or Rectangular. If Cylindrical, diameter 9 cm (+ 15%) or in proper / viable proportion of the mentioned diameter for the purpose of industrial or commercial utilisation. Having height 30 cm (± 20%) or in proper / viable proportion of the mentioned height for the purpose of industrial or commercial utilisation. . If Rectangular, then having sides ad- measuring 8cm (+ 15%) each or in proportion of 8 cm and height of 30 cm (± 15%) or in proportion of 30 cm for the purpose of industrial or commercial utilisation. An Air-tight lid is provided. One Vent of 2 cm (± 15%) diameter or in proportion of the mentioned size coking chamber still at the upper side of coking chamber is provided which can be exactly fitted to a condensing system / device via Mild steel or Stainless Steel Tube.

An arrangement is made to measure the volume & rate of flow of distillate, continuously or intermittently at any point of time. This receiving assembly can be cooled down by suitable cooling device up to [-]20 °C or it can be heated up to 100° C, as and when required. This receiving container is provided with outlet vent for exit of Coker Gases which can be collected and utilised. Received Liquid or gas fuels can be partially utilised to raise the temperature of cocking chamber/ section. Thus at such stage the full process and apparatus runs without any outside energy. The principle object of this invention is therefore to provide an improved apparatus for the utilisation and conversion of waste plastic into usable product such as petrol / kerosene / diesel / furnace oil / lubricating oil 8 fractions, petroleum gases & coke. All are usable products that too without any waste or hazardous by-product. Still further object of this invention is to provide an improved apparatus for manufacturing of Petrol / Kerosene/ diesel/ furnace oil / lubricant oil fractions, Petroleum gases and coke from any type of waste plastic and refinery waste, refinery residue, coal tar or any type of secondary residue or any type of waste oil to obtain higher yield of distillates at controlled temperature.

With an electronic / electrical device to control & monitor the temperature within the coking chamber and other sections to achieve higher yields of distillate with high purity thereby cost effective, safe and user friendly. Still further object of this invention is to provide an improved apparatus for manufacturing of Petrol / Kerosene/ diesel/ furnace oil/ lubricating oil fractions, Petroleum gases and coke from any type of waste plastic and refinery waste, refinery residue, coal tar or any type of secondary residue or any type of waste oil wherein a value added useful product is obtained from the waste material. 9 Example 1: After ensuring that the coking chamber/ still is cleaned from inside, about 250 to 500 grams of feed ( combination of raw material chemical A and B in different ratios ranging 1:3,1:1, 3:1 or other proportions/ratios) is accurately weighed and put inside the coking still. Additives mentioned are added. The lid of the still is tightened with flanges in order to avoid any leakage. An additional gasket is also provided for the same purpose. After setting the unit as already described, heating of coking chamber/still and circulation of water/ thermic fluid is started. The temperature within the condenser is lowered by circulation of chilled water/ thermic coolant for condensation of vapours coming our of coking chamber. The heating process of coking chamber is well controlled and can be either slower or accelerated at any moment. The time of first drop of distillate coming is noted properly along with corresponding Temperature reading. Towards the end, the waxy material may come. So to keep distillate in liquid state, hot water/Thermic fluid is circulated through the condenser rube in latter stage. In the beginning the distillate evolution is more and reaches maximum and then the rate of distillate evolution falls and the rate of gas evolution increases. Then, the distillate evolution stops, finally the gas evolution also stops, and a final 30 minutes heating is required for the completion of coking. Then, the heating is stopped and the coking still is allowed to cool to the room temperature. After cooling, coking still is opened and coke inside the still is taken out and collected. The amount of coke formed is established by weighing. The volume of distillate formed with time was noted. And then the amount of total distillate & gases formed are also found out. 10 The total distillate collected is transferred to a flask. First this total distillate was analyzed for important properties like specific gravity, viscosity (Kinematic or Redwood), aniline point, refractive index etc. Next the ASTM distillation of total distillate was carried out and different fractions namely fraction I - IBP-140°C (Light Naphtha cut), Fraction II- 140°C- 200°C (Heavy Naphtha and gasoline component), fraction III - 200°C-250°C (kerosene fraction), fraction IV - above 250°C (Diesel Fractions furnace oil / Lubricating Oil were collected). From these by blending fraction I (IBP-140°C) and fraction II (140-200°C) full range motor Gasoline fraction (IBP - 200°C) is made. By blending fraction II (140-200°C) and fraction III (200-250°C) a new full range kerosene fraction (140-250°C) is made which is tested for kerosene. Fraction IV above (250°C) is tested for high-speed diesel, furnace oil & Lubricating oil. Different properties namely specific gravity, viscosity, aniline point and refractive index of each of these fractions were determined by BIS/IP/ASTM methods. The proximate analysis of the petroleum coke formed was also found out as per BIS standards. This is an embodiment of the invention. Several modifications are possible may be considered within the ambit and spirit of this invention. Since many modifications, variations and changes in detail may be made to the above described embodiments, it is intended that all matters described in the foregoing description as described in the accompanying specifications. 11 * fcyx 29JAJJ Effect of Addition of various Waste Plastics on the yeilds Studies of Progress of Reaction Result with and without Plastic. 2 9 JAN MW I CLAIM :- 1.
