摘要： A process for upgrading of a coal product is provided. The process comprising the steps of: (i) providing a purified coal composition, wherein the composition is in the form of solid particles, and wherein at least about 90% by volume (%vol) of the solid particles are no greater than about 500 µm in diameter; and(ii) combining the purified coal composition with a solid coal feedstock, in order to create a combined solid-solid blend upgraded coal product. Further aprocess for preparation of a purified coal product is provided. The process comprising the steps of:obtaining a starting material that comprises coal; subjecting the starting material to at least one fine grinding stage so as to reduce the starting material to a particulate composition in which substantially all of the particles are no more than 500 microns (µm) in diameter; exposing the particulate composition to at least one froth flotation stage so as to separate hydrocarbonaceous material comprised within the particulate composition from mineral matter, wherein during the at least one froth flotation stage the hydrocarbonaceous material is associated with froth produced and separated from the at least one froth flotation stage; washing the froth separated from the at least one froth flotation stage with water to release the hydrocarbonaceous material; and subjecting the hydrocarbonaceous material to at least one dewatering stage so as to obtain a particulate purified coal product that has an ash content of less than 12%m, a water content of less than 25%m and wherein the particles comprised within the particulate purified coal product have a d90of less than 00 µm. Products, such as pelletized or briquetted coal,comprising purified coal material obtainable via the described processes are also provided.

摘要： Processes are described for the production of a pitch for use in the manufacture of carbon composite materials. The process comprises the steps of providing a purified coal product (PCP), wherein the PCP is in particulate form, and wherein at least about 90% by volume (%v) of the particles are no greater than about 25 µm in diameter; wherein the PCP has an ash content of less than about 10%m; and combining the PCP with a feedstock for pitch to create a combined blended mixture suitable for thermal reaction followed by distillation to create a resultant pitch. The combined blended mixture comprises at least around 0.1 %m and at most around 90%m PCP. Composite materials that find utility as carbon electrodes, particularly electrolytic baked carbon anodes, can be made from combining the pitch and PCP with a filler material, such as a pet coke.

摘要： Processes and compositions are provided for asphalts, asphalt binder, and asphalt concrete. The process for making asphalt compositions comprises the steps of (i) providing a purified coal product (PCP), wherein the PCP is in particulate form, and wherein at least about 90% by volume (%v) of the particles are no greater than about 25 μm in diameter; wherein the PCP has an ash content of less than about 10 wt% and a water content of less than about 5 wt%; and (ii) combining the PCP with an asphalt feedstock to create a combined blended mixture; wherein the combined blended mixture comprises at least about 0.1 wt% and at most about 50 wt% PCP. The asphalt compositions may be combined with aggregate to provide asphalt concrete compositions. Methods are also provided for the use of PCP as an additive in the manufacture of asphalt containing compositions.

摘要： Activated carbon (AC) produced from agglomerated purified carbonaceous product (PCP) are provided. The PCP is in particulate form, at least about 90% by volume (%v) of the particles are no greater than about 25 J.lm in diameter; the PCP has an ash content of less than about 5%m and a water content of up to about 60 %m. The PCP may be used to make AC, or utilized as an additive for production of AC from other carbonaceous feedstocks.

摘要： There is provided a process for the production of anisotropic coke, the process comprising providing a purified coal product (PCP), wherein the PCP is in particulate form, and wherein at least about 90% by volume (%v) of the particles are no greater than about 100 µm in diameter; wherein the PCP has an ash content of less than about 10%m and a water content of less than around 5%m. The PCP is combined with a feedstock oil, such as a decant oil, in order to create a combined solid-liquid blend, wherein the solid-liquid blend comprises at least around 0.1 %m and at most around 50%m PCP. The solid-liquid blend is subjected to a temperature in excess of 400 °C, typically as part of a delayed coker process, for a time period sufficient to induce formation of mesophase, and production of anisotropic coke. Improved yields of valuable needle coke can be obtained via the processes described.
