    Abstract: Surface-oxygenated biochar compositions and sonication-ozonization methods create advanced hydrophilic biochar materials having higher cation exchange capacity, optimized pH, improved wettability, and toxin free components. These sonicated and ozonized biochar compositions are used as filtration materials for clean water and air, as phosphorus solubilizing reagents to mix with phosphate rock materials to make a slow-releasing phosphate fertilizer, as biochar soil additives to help solubilize phosphorus and reduce phosphorus fertilizer additions required to achieve desired soil phosphorus activity, crop uptake, and yield goals, as sand soilization reagents by utilizing their liquid gel-forming activity in the spaces among sand particles to retain water and nutrients and hold the sand particles together, as plant growth stimulants by using the humic acids-like surface-oxygenated biochar substances at a proper ppm concentration and as carbon sequestration agents to help control climate change for energy and environmental sustainability on Earth.

    Abstract: A system includes a heat exchange system and a power generation system. The heat exchange system includes first, second, and third heat exchangers each operable as a continuous source of heat from a delayed coking plant. The first and second heat exchangers heat first and second fluid streams to produce heated first and second fluid streams, respectively. The heated second fluid stream has a lower temperature and a greater quantity of heat than the heated first fluid stream. The third heat exchanger heats a third fluid stream to produce a heated third fluid stream that includes the heated first fluid stream and a hot fluid stream. The heated third fluid stream has a lower temperature than the heated first fluid stream. The power generation system generates power using heat from the heated second and third fluid streams.

    Abstract: A process for treating agglomerating coal includes drying coal in a drying step, and treating the dried coal in an oxidizing step to form oxides sufficient to convert the coal into a substantially non-agglomerating coal. The oxidized coal is pyrolyzed in a pyrolysis step to form coal char, and the coal char is cooled. At least one of the drying, oxidizing, and pyrolyzing steps is a dual zone step, with the dual zone step having a first zone and a second zone, with the temperature of the second zone being higher than that of the first zone.
