    Abstract: The present invention addresses the processing of waste and low-value products to produce useful materials in reliable purities and compositions, at acceptable cost, without producing malodorous emissions, and with high energy efficiency. In particular, the invention comprises a multi-stage process that converts various feedstocks such as offal, animal manures, municipal sewage sludge, tires, and plastics, that otherwise have little commercial value, to useful materials including gas, oil, specialty chemicals, and carbon solids. The process subjects the feedstock to heat and pressure, separates out various components, then further applies heat and pressure to one or more of those components. Various materials produced at different points in the process may be recycled and used to play other roles within the process. The invention further comprises an apparatus for performing a multi-stage process of converting waste products into useful materials, and at least one oil product that arises from the process.

  • Patent number: 8318997
    Abstract: Techniques, systems, apparatus and material are disclosed for generating renewable energy from biomass waste while sequestering carbon. In one aspect, a method performed by a reactor to dissociate raw biomass waste into a renewable source energy or a carbon byproduct or both includes receiving the raw biomass waste that includes carbon, hydrogen and oxygen to be dissociated under an anaerobic reaction. Waste heat is recovered from an external heat source to heat the received raw biomass waste. The heated raw biomass waste is dissociated to produce the renewable fuel, carbon byproduct or both. The dissociating includes compacting the heated raw biomass waste, generating heat from an internal heat source, and applying the generated heat to the compacted biomass waste under pressure.

  • Publication number: 20120285862
    Abstract: A process and apparatus for improving the production of coke having a high volatile combustible material content are disclosed. The process may include, for example: heating a coker feedstock to a coking temperature to produce a heated coker feedstock; contacting the heated coker feedstock with a quench medium to reduce a temperature of the heated coker feedstock and produce a quenched feedstock; feeding the quenched feedstock to a coking drum; subjecting the quenched feedstock to thermal cracking in the coking drum to (a) crack a portion of the quenched feedstock to produce a cracked vapor product, and (b) produce a coke product having a volatile combustible material (VCM) concentration in the range from about 13% to about 50% by weight, as measured by ASTM D3175.

  • Publication number: 20120261247
    Abstract: A process is described for treating waste plastics material to provide at least one on-specification fuel product. Plastics material is melted and then pyrolysed in an oxygen-free atmosphere to provide pyrolysis gases. The pyrolysis gases are brought into contact with plates in a contactor vessel so that some long chain gas components condense and return to be further pyrolysed to achieve thermal degradation. Short chain gas components exit the contactor in gaseous form and proceed to distillation to provide one or more on-specification fuel products. A pipe directly links the pyrolysis chamber to the contactor, suitable for conveying upwardly-moving pyrolysis gases and downwardly-flowing long-chain liquid for thermal degradation.

  • Patent number: 8266812
    Abstract: An apparatus for torrefaction of water containing cellulosic materials is performed in an inert atmosphere. The cellulosic material is cascaded through the apparatus between a plurality of rotatable trays vertically stacked within multiple processing zones. Steam being generated from heating of the cellulosic material is recycled back to the apparatus to provide an inert atmosphere. The steam may be superheated in a heat exchanger. Exhaust from the torrefaction zone of the apparatus has some moisture and other volatiles removed prior to being reheated in a burner. The heated exhaust is used in the heat exchanger to superheat the recycled steam.

  • Publication number: 20120181160
    Abstract: This invention relates to systems and methods for converting biomass into highly inert carbon. Specifically, some embodiments densify the carbon into anthracite-style carbon aggregations and store it in geologically stable underground deposits. The use of certain embodiments yield a net effect of removing atmospheric carbon via the process of photosynthesis and converting it into hard coal, which can be stored in underground beds that mimic existing coal deposits which are known to be stable for thousands of years.

  • Publication number: 20120175236
    Abstract: A system and a method of decomposing organic waste are provided. The system decomposes organic waste in a decomposition chamber without use of enzymes, additives, or microorganisms. In one embodiment, the system decomposes organic waste within 24 hours and deodorizes the odor of decomposing organic waste during decomposition process. The system provides sufficient heat and operating conditions to evaporate moisture from the organic waste without burning the organic waste. The byproduct of the organic waste after decomposition process by the system is substantially homogeneous material that is reduced in volume compared to the organic waste. In one embodiment, the system reuses or recycles water and heat used in the system for different processes in the system. The system includes a blower that provides flow of the moisture inside the system.

  • Publication number: 20120160658
    Abstract: A process and system is disclosed for optimizing a key parameter of a biomass feedstock that enhances bio-oil production. The process and system involves optimizing the values of the key parameter in multiple biomass feedstocks by regulating their feed rates and blending those feedstocks to produce a cumulative biomass feedstock with an optimal value for the key parameter. The key parameter in the biomass feedstocks is measured and the feed rates of the multiple biomass feedstocks are adjusted in order to produce a cumulative biomass feedstock exhibiting optimal values for the desired key parameter. The key parameters can include compositional properties, such as lignin content or mineral content, and/or fluidization properties of the biomass materials, such as density, particle cohesion force, or particle size.
