Abstract:
Disclosed is a fuel additive concentrate having a high flash point which is characterized by a viscosity controlled for dosing in a Bernoulli feed device. The concentrate is high temperature stable and is in a form suitable for on-board dosing of fuel which can provide predictable feed rates from a feed device. It comprises a fuel soluble platinum group metal composition and/or a fuel soluble or dispersible cerium composition and/or a fuel soluble or dispersible iron compound and a high flash aromatic solvent. The solvent and the metal composition or compositions are present in relative amounts to provide a FBC concentrate having a flash point (ASTM D93-85) of greater than 140°F and, a preferred kinematic viscosity within the range of from 7 to 25 centistokes, as measured by ASTM D445 at 105°F.
Abstract:
Disclosed is a process for the upgrading of heavy oils and bitumens, where the total feed to the process can include heavy oil or bitumen, water, and diluent. The process can include the steps of solvent deasphalting (110) the total feed (105) to recover an asphaltene fraction (116), a deasphalted oil fraction (118) essentially free of asphaltenes, a water fraction (112), and a solvent fraction (114). The process allows removal of salts from the heavy oils and bitumens either into the aqueous products or with the asphaltene product.
Abstract:
A process (10) for the manufacture of form coke includes briquetting (22) an admixture of particulate hard coking coal (HCC), particulate semi-soft coking coal (SSCC), a particulate carbon-containing filler other than hard coking coal or semi-soft coking coal, and a binder to form briquettes. The hard coking coal has a particle size distribution with a D90 value of no more than 500 µm, the semi-soft coking coal has a particle size distribution with a D90 value of no more than 500 µm, and the carbon-containing filler has a particle size distribution with a D90 value of no more than 500 µm. The hard coking coal makes up at most 30% by mass of the admixture and the carbon-containing filler makes up at least 10% by mass of the admixture. The briquettes are carbonised (24) at a temperature of at least 900°C to provide form coke.
Abstract:
A system and method for producing solid pellets from a slurry HDC pitch is disclosed which utilizes a polymer additive that is mixed with the pitch to increase the softening point of the solid pellets.
Abstract:
In one embodiment, a method for processing carbonaceous materials that includes introducing a first source of carbonaceous material as a first feedstock into a mixer. Then, a second source of carbonaceous material is introduced as a second feedstock into the mixer. The second feedstock is one of the outputs of the processing of the carbonaceous materials. These carbonaceous materials are mixed into a single feedstock of carbonaceous materials that is customized into a predetermined material composition, and this predetermined mixture is then pyrolyzed in a pyrolyzer to produce a custom carbonaceous output. Other embodiments are also disclosed.
Abstract:
In embodiments of the present invention, a method of heat treating a solid fuel briquette may include heating the solid fuel briquette using energy from at least one of a heat furnace or an electromagnetic energy system of a solid fuel treatment facility as the solid fuel briquette is moved through the treatment facility to a specified internal temperature, and sealing the heat-treated solid fuel briquette in a vessel for a duration of time. methods and systems for processing solid fuel.
Abstract:
The invention relates to a method for producing formed pieces, especially briquettes, from a fine-grained to medium-grained mixed material using binders. The method according to the invention comprises a first step of heating the mixed material to a temperature required for forming, and a second, atmospherically separate step, of mixing the mixed material with binders, and subsequent process steps. The method allows the avoidance of health hazards caused by emissions.
