Abrégé

Methods and systems disclosed herein can treat biomass compositions to produce valuable products, reduce emissions, and decarbonize biomass. The biomass compositions can be raw biomass (e.g., green, woody-plant derived) or waste biomass (e.g., industrial waste, pulp and paper processes, construction materials). The biomass compositions can be mixed with a reagent to form a mixture. The reagent can include ammonia. The mixture can be reacted to separate one or more components from the biomass and form a treated biomass composition. The one or more components can include lignin, polylactic acid, carbon oxides, methane, minerals, volatiles, or semi-volatiles. The treated biomass can be dried and processed into heating pellets that have higher calorific value and fewer emissions than conventional heating chips. The separated components can be used to produce valuable products, such as wood composites, bioplastics, fertilizer, fuels, lignin anodes for batteries, additives, glues, resins, and bio-based carbon fiber.

A method of processing coal to remove sulfur and other contaminants by mixing coal in a solution of aqueous ammonia having a selected concentration range (preferred range of 3%-5%) of ammonia to water in a reaction vessel. The mixing causes the solution to be brought into contact with the surfaces and pores of the coal. The process is monitored to detect when the concentration of aqueous ammonia in the reaction vessel has fallen below the selected range, and aqueous ammonia with an ammonia concentration in or above the selected range is fed into the reaction vessel to return the solution to within the selected range. The cleaned coal may be rinsed and dried, or dried without rinsing to form an ammonia coating on the coal surfaces and pores. Several plant layouts to practice the method are described.
