Definitions

  • the present invention relates to pyro-catalytic continuous process for conversion of carbonaceous homogenous and/or heterogeneous, segregated or unsegregated, wet or dry multi-feed waste material into hydrocarbon fuels and solid carbon in presence of external agglomerated nano catalyst.
  • the invention also relates to a compact, modular, economic and simple to operate processing plant for pyro-catalytic cracking of said waste material into value added eco-friendly fuels and industrially usable solid carbon mass.
  • the feed stocks which are generally waste materials, are almost moist, contaminated, un-segregated, non-homogeneous and homogeneous blends and as such cannot be processed by conventional methods. Segregation, washing and drying are expensive procedure which makes the processes un-economic. Besides, there are environmental costs to the cleaning process as the water and detergents used in the washing process add to the cost and disposal concerns. Further, the drying process requires energy and increases the cost of processing.
  • the end product is either a syngas having a low calorific value or a liquid fuel having a high viscosity with a low value generation for the processors.
  • US5811606 describes a process for treating waste plastics including adding the waste plastics and a catalyst into a reactor for catalytic cracking to obtain gasoline and diesel oil.
  • the patent teaches mixing of powdered catalyst intrinsically into viscous reactants, such as molten plastic in this case, which leads to non-uniform mixing and incomplete and inefficient cracking leading to waxy and inconsistent products.
  • Such a process and its equipment are not conducive to handle unprocessed, moisture laden wastes.
  • Volatile vapours generated in the process tend to pose a dangerous explosive hazard should there be any leaks. Residual products that cannot be reutilised may pose yet another disposal issue.
  • US7473348 discloses a process for production of diesel oil from hydrocarbon-containing residues in an oil circuit with solids separation and product distillation for the diesel product with energy input by means of pumps and counter rotating agitators and by the use of fully crystallized catalysts of potassium, sodium, calcium, and magnesium-aluminium silicates, where all surfaces are cleaned continuously by the agitator mechanisms.
  • WO 2005/087897 describes a process and plant for . the thermocatalytic conversion of plastic waste materials into reusable fuels and a fuel produced by the process involving the steps of delivering melted plastic material to one or more pyrolysis chambers via heated and valved manifolds and effecting pyrolysis of the plastic material into a gaseous state in an oxygen purged and pressure controlled environment. Pyrolytic gases are then transferred to a catalytic converter where the molecular structure of the gaseous material is altered in structure and form, followed by transferring gases to one or more condenser means to distil and cool gases into separate fractions.
  • the said condenser system is operated at a temperature ranging from 60°C to 8°C where the gases are selectively cooled and distilled at the said temperature.
  • the application proposes use of a conventional catalytic reactor tower that uses high surface area metal plates arranged in a torturous path as catalysts.
  • the catalysts are selected from from a special catalytic metal alloy including MCM-41, silicates of iron , cobalt, nickel, manganese, chromium etc and the chamber is heated to 220C for selected pyrolysis to obtain a fuel with a carbon chain in the range of C8-C25 peaking at C I 6 (octane).
  • the plant in said application described includes a) commuting means for breaking the waste material into particulate matter ; b) melting means for receiving and melting the particulate waste maternal ; c) pyrolysis chamber for receiving waste material, the pyrolysis chamber operative to: i) seal the chamber from the environment and to purge air-borne oxidants from the pyrolysis chamber by the introduction of a non-oxidising gas; and ii) heat the waste material to effect pyrolysis of the waste material into a gaseous state in a substantially air-borne oxidant-free and pressure-controlled environment ; d) catalytic converter means, consisting of metallic plates having a torturous path for contact with the pyrolysed gases, operative to receive and crack the gaseous waste material whereby the molecular structure of the gaseous material is altered ; and e) condenser means operative to receive, cool and separate the cracked gaseous material into fractions to form at least one type.
  • the said arrangement thus becomes bulky and inconvenient for serviceability and maintenance and requires a halt in the working of the plant in order to carry out the servicing and maintenance.
  • the functioning of the said tower is dependent upon maintaining its temperature to 220°C thus adding additional steps and components required in the process.
  • the non-condensable gases and the liquid fuels have to undergo additional filtration and scrubbing steps thus adding to additional equipment, increased capital cost and need for costly maintenance in the operation of the plants.
  • the process described in said application is selective to plastics as waste feed material.
  • a German application DE 3503069 discloses a rotary-drum reactor, which is indirectly heated by means of a flowing heat transfer medium, comprising a rotatably mounted, drivable shell tube and a plurality of tubes or tube sections arranged within the shell tube in which, the tubes or tube sections arranged in the interior of the shell tube are designed as material tubes for the throughput of the material to be reacted.
  • the material tubes can be heated indirectly and individually by means of liquid heat transfer media, and the outer wall of the shell tube does not come into contact with the heat transfer medium.
  • Each of the plurality of material tubes preferably is covered with the heating coils and is heated indirectly.
  • the reactor is preferably used for pyrolysis.
  • the process is characterized in that the indirect heating is accomplished by using a salt melt as the heat transfer medium.
  • a salt melt as the heat transfer medium.
  • the conventional processes and the plant units for the processes of applications described hereinabove are targeted to convert one or two limited feed stocks into end products, the processes require pre-segregation and pre-processing, the processes cannot handle waste in an un-segregated manner and the catalysts have low efficiency at low temperature affecting the yield of liquid hydrocarbon fuels, produce gas with low calorific value.
  • the conventional processes of thermal cracking and catalytic cracking are preceded separately at high temperature leading to high consumption of energy and carbonization of raw material thereby leading to low yield and quality of oil and gas.
  • Equipment seen in the prior art fail to embody higher levels of safety and minimize accidental hazards.
  • the object of the invention lie in providing a process/ means which is convenient, safe, operates at the optimal vaporization temperature of the various types of feed material in a single chamber, and has a methodical way of disposal of untreated and other residual discharge which can be recycled and reused in a continuous manner.
  • the present invention provides a process for the conversion of un-segregated or segregated, wet or dry, co-mingled, carbonaceous homogenous and/or heterogeneous, contaminated, moist material as individual feed or multi-feed into usable hydrocarbon liquid fuels and carbon, which are all fuels having a high end product value, by a pyro- catalytic process using agglomerated nano catalyst, embedded in multifunctional cartridges, that is not mixed with the processed input material.
  • the present invention can process almost any feed stock wet or dry, in an unsegregated/segregated mode/form, containing hydrogen-carbon bonds within their molecular structures to produce combustible fuel, liquid fuels and carbon residue.
  • the present invention provides a pyro-catalytic continuous process of conversion of carbonaceous homogenous and/or heterogeneous waste feed into usable combustible fuels and solid carbon, using external agglomerated nano catalyst, the said process involving the following steps;
  • step (b) Pyro-catalytic cracking of the intermediate vapors of higher molecular weight hydrocarbons of step (b) by passing the vapors through field ⁇ replaceable multifunctional cartridges loaded with agglomerated nano catalyst in the processing plant to obtain gases/ vapors of low molecular weight hydrocarbons and others;
