Abstract:
Methods for fractional catalytic pyrolysis which allow for conversion of biomass into a slate of desired products without the need for post-pyrolysis separation are described. The methods involve use of a fluid catalytic bed which is maintained at a suitable pyrolysis temperature. Biomass is added to the catalytic bed, preferably while entrained in a non-reactive gas such as nitrogen, causing the biomass to become pyrolyzed and forming the desired products in vapor and gas forms, allowing the desired products to be easily separated.

Abstract:
The invention relates to devices for treating liquid carbonous fuel. The inventive device comprises external and internal electrodes, which are coaxially arranged in such a way that a treatment chamber connected to a fuel line by means of inlet and outlet channels is formed therebetween, and a dielectric insert placed between the electrodes. The outlet channel is located along the longitudinal axis of the electrodes. The external electrode is embodied in the form of a bolt which is fixable to the fuel line body by means of an external thread. The inlet channel is formed by means of at least one orifice connecting the bolt external surface, which is located between the bolt head and the end face thereof opposite to the head, to the treatment chamber. The internal electrode is extended beyond the end face of the bolt head through a dielectric sleeve. The inlet and outlet channels are embodied according to a relationship (I), wherein Sin is the cross-section area of an i-th inlet channel, n is the number of inlet channels and Sout is the cross-section area of the inlet channel. ∑ i = 1 n S iB Π = ( 0 , 1 ÷ 2 , 7 ) S B H Π ( 1 )
Abstract:
This invention provides processes for producing fuel, particularly transportation fuel, from biological material, e.g., lipid material. One aspect of the invention involves hydroprocessing a feedstock in a hydroprocessing zone that is maintained at conditions that promote the efficiency of converting the lipid-containing feedstock into transportation fuel. Such conditions include one or more of maintaining CO content of the hydroprocessing zone at a predetermined amount and recycling or providing a hydrogen-containing gas to the hydroprocessing zone that has been treated to remove CO.
Abstract:
The present invention discloses a nano-granule fuel oil, which substantially contains no granule greater than 10 nm. This nano-granule fuel oil can be obtained by treating conventional fuel oils under a magnetic field with a air gap magnetic field intensity of at least 8000 Gauss and a magnetic field gradient of at least 1.5 tesla/cm. The nano-granule fuel oil of the present invention significantly improves the combustion degree of fuel oil as compared with the conventional fuel oils. Its application can considerably economize fuel oil and reduce the emissions of CO and the like in tail gas.
Abstract:
A waste-to-energy cogeneration system is described in various embodiments. The system can convert certain fuel-laden waste to thermal energy and electrical power. In certain embodiments, fuel-laden waste which has not been pre-filtered or pre-treated to remove particulates and water is deposited in the cogeneration system and prepared by the system for combustion in an unmodified diesel engine. The fuel-laden waste can comprise oils, greases and fats from food preparation which are contaminated with water and particulates. Thermal and mechanical energy produced by the engine are utilized to provide thermal energy and electrical power external to the cogeneration system.
Abstract:
In a method for producing high carbon content products from biomass, a biomass oil is added to a cracking reactor vessel. The biomass oil is heated to a temperature ranging from about 100° C. to about 800° C. at a pressure ranging from about vacuum conditions to about 20,700 kPa for a time sufficient to crack the biomass oil. Tar is separated from the cracked biomass oil. The tar is heated to a temperature ranging from about 200° C. to about 1500° C. at a pressure ranging from about vacuum conditions to about 20,700 kPa for a time sufficient to reduce the tar to a high carbon content product containing at least about 50% carbon by weight.
Abstract:
A method and apparatus involve: determining a specification for a fuel volatility characteristic so that a fuel complying with the specification meets an applicable regulatory requirement for volatility with or without the addition of ethanol; and utilizing a fuel blending mechanism to blend a plurality of different fuel components in a manner meeting the specification. A different aspect involves a computer-readable medium storing a computer program that, when executed: determines a specification for a fuel volatility characteristic so that a fuel complying with the specification meets an applicable regulatory requirement for volatility with or without the addition of ethanol; and causes a fuel blending mechanism to blend a plurality of different fuel components in a manner meeting the specification.
Abstract:
Disclosed is a method of monitoring and optimizing the concentration of a denaturant composition in a fuel ethanol. The method includes adding a known amount of the denaturant composition to the fuel ethanol to create a treated fuel ethanol. A measured spectroscopic absorbance or transmittance signal provides information for determining the concentration of the denaturant composition in the fuel ethanol. A component in the denaturant composition is capable of providing the spectroscopic absorbance or transmittance signal or capable of being chemically derivatized to provide a spectroscopic absorbance or transmittance signal. Based upon the measured spectroscopic absorbance or transmittance signal, the concentration of the additive composition in the fuel ethanol may be adjusted.
Abstract:
The present invention addresses the processing of waste and low-value products that contain bone material to produce useful materials in reliable purities and compositions, at acceptable cost, and with high energy efficiency. In particular, the invention comprises a process that converts various feedstocks such as offal, animal manures, and municipal sewage sludge, to useful materials including gas, oil, specialty chemicals, and carbon solids. The process heats the feedstock in order to breakdown proteins and separate organic material from bone material, applies further heat and pressure to the resulting liquid mixture, separates out various components, then further applies heat and pressure to one or more of those components. The invention further comprises an apparatus for performing a process of converting waste products into useful materials, and an oil product that arises from the process.
