HIGH-CARBON BIOGENIC REAGENTS AND USES THEREOF
This invention provides processes and systems for converting biomass into high-carbon biogenic reagents that are suitable for a variety of commercial applications. Some embodiments employ pyrolysis in the presence of an inert gas to generate hot pyrolyzed solids, condensable vapors, and non-condensable gases, followed by separation of vapors and gases, and cooling of the hot pyrolyzed solids in the presence of the inert gas. Additives may be introduced during processing or combined with the reagent, or both. The biogenic reagent may include at least 70 wt %, 80 wt %, 90 wt %, 95 wt %, or more total carbon on a dry basis. The biogenic reagent may have an energy content of at least 12,000 Btu/lb, 13,000 Btu/lb, 14,000 Btu/lb, or 14,500 Btu/lb on a dry basis. The biogenic reagent may be formed into fine powders, or structural objects. The structural objects may have a structure and/or strength that derive from the feedstock, heat rate, and additives.

METHOD FOR REMOVING ASH FROM SOLID CARBONACEOUS MATERIAL
A method for removing ash from a solid carbon material: Reaction conditions are mild, and ash may be removed more effectively. The ash removing method comprises: S1) mixing an alkaline sub-molten salt medium and a solid carbonaceous material to be treated, heating so that alkali and ash in the solid carbonaceous material to be treated react in the alkaline sub-molten salt medium, and performing solid-liquid separation on a mixed slurry resulting from the reaction to obtain a first solid product and an alkali treatment solution, wherein in the alkaline sub-molten salt medium, the mass fraction of the alkali is greater than or equal to 50%; S2) using an acid solution to perform acid cleaning treatment on the first solid product, and performing solid-liquid separation again to obtain a second solid product and an acid cleaning solution.
SOLID-LIQUID CRUDE OIL COMPOSITIONS AND FRACTIONATION PROCESSES THEREOF
A process for the production of a fractionated product is disclosed, comprising providing a solid hydrocarbonaceous material, wherein the material is in particulate form, and wherein at least about 90% by volumic (% v) of the particles arc no greater than about 500 μm in diameter. The solid hydrocarbonaceous material is combined with an unrefined liquid hydrocarbonaceous material, such as crude oil, in order to create a combined solid-liquid blend; and the combined solid-liquid blend is subjected to fractionation in order to generate one or more fractionation products. Typically the solid hydrocarbonaceous material comprises coal, optionally the coal is ultrafine coal, and suitably the coal is comprised of microfine coal. The coal may be dewatered and deashed prior to combination with unrefined liquid hydrocarbonaceous material. Compositions and products of the process are further provided.

PROCESS FOR PRODUCING BRIQUETTES FROM A WASTE MATERIAL AND BRIQUETTE MADE OF A WASTE MATERIAL
A method for producing briquettes made of a waste material includes provisioning of at least one metal and at least one organic material. The waste material is mechanically prepared in a single or multiple stages and at least one first fraction of the waste material is separated. A briquette mixture containing the at least one first fraction is produced, wherein the at least one first fraction has a calorific value of 0 MJ/kg to 30 MJ/kg. A calorific value of the briquette mixture is adjusted by varying at least the first fraction. The briquette mixture is introduced into a briquetting device and pressed into briquettes. Briquettes with a calorific value of 5 MJ/kg to 30 MJ/kg and with a maximum copper content of 0.1 wt % to 20 wt % are produced.
