Abstract:
One aspect of this invention is a method of recovering a bio-oil product by heating a biomass at reaction conditions to produce a bio-oil. The bio-oil is then mixed with biodiesel. The bio-oil/biodiesel mixture is then further mixed with petroleum diesel to form a miscible multi -component diesel fuel mixture.
Abstract:
Briefly described, embodiments of this disclosure include methods of recovering bio-oil products, fuels, diesel fuels, and the like are disclosed.

Abstract:
A process for making a hydrogenated carbon material Is provided which includes forming a mixture of a carbon source, particularly a carbonaceous material, and a hydrogen source. The mixture is reacted under reaction conditions such that hydrogen is generated and/or released from the hydrogen source, an amorphous diamond-like carbon is formed, and at least a portion of the generated and/or released hydrogen associates with the amorphous diamond-like carbon, thereby forming a hydrogenated carbon material. A hydrogenated carbon material including a hydrogen carbon clathrate is characterized by evolution of molecular hydrogen at room temperature at atmospheric pressure in particular embodiments of methods and compositons according to the present invention.
Abstract:
Elemental sulfur is combined with either liquid anhydrous ammonia, liquid sulfur dioxide, or both to form a solution or slurry which is transportable through pipelines or other transport vessels without a risk of clogging due to the environmental temperature drops that these vessels typically encounter. This unusual behavior and the advantages it offers arise from the discovery of unexpected solubility vs. temperature relationships of elemental sulfur in each of these two carriers. Among the advantages are significant improvements in the economics of many industrial chemical processes that involve the presence of sulfur either in elemental or chemically combined form, including natural gas or tar sands production and processing, hydrogen sulfide abatement, hydrogen production without carbon dioxide emissions, and sulfur extraction from ores, subterranean deposits, depositories, or fouled impaired industrial facilities. Large-scale ramifications for energy and fertilizer mineral resource utilization, greenhouse gas abatement, hydrogen economy, and nitrogen fertilizer production are taught.
Abstract:
The present invention constitutes a heat treatment apparatus like a fluidized-bed dryer for heat treating a particulate material in a low temperature, open-air process. Preferably, available waste heat sources within the surrounding industrial plan operation are used to provide heat to the dryer. Moreover, conveyor means contained within the dryer can remove larger, denser particles that could otherwise impede the continuous flow of the particulate material through the dryer or plug the fluidizing dryer. This invention is especially useful for drying coal for an electricity generation plant.
Abstract:
The present invention harvests and utilizes fluidized bed drying technology and waste heat streams augmented by other available heat sources to dry feedstock or fuel. This method is useful in many industries, including coal-fired power plants. Coal is dried using the present invention before it goes to coal pulverizers and on to the furnace/boiler arrangement. Coal can be intercepted on current coal feed systems ahead of the pulverizers. Drying fuel, such as coal, is done to improve boiler efficiency and reduce emissions. A two-stage bed utilized in the process first "pre-dries and separates" the feed stream into desirable and undesirable feedstock. Then, it incrementally dries and segregates fluidizable and non-fluidizable material from the product stream. This is all completed in a low-temperature, open-air system. Elevation of fan room air temperature is also accomplished using waste heat, thereby making available to the plant system higher temperature media to enhance the feedstock drying process.
Abstract:
A method of purifying a biodiesel fuel by contacting the biodiesel fuel with at least one adsorbent material, such as magnesium silicate. Such method removes impurities, such as soap, formed during the production of biodiesel fuels.
Abstract:
A novel fuel composition suitable for fueling fluid bed reactors has been discovered. The fuel composition comprises a mixture of a combustible base, a densifying component, and a binder. The fuel composition can be formed into a briquette that is stable in a fluid bed reactor. The amount of densifying component can be adjusted to produce briquettes that exhibit neutral density in the fluid bed. At neutral density the briquettes will mix throughout the fluid bed. If desired, higher levels of densifying component can be utilized to make briquettes that sink in the fluid bed such that they remain in the combustion zone of the fluid bed. The fuel compositions of the present invention allow the use of inexpensive fuels as the combustible base, such as waste petroleum coke and coal.
