TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The system further comprises: a pretreatment chamber that is configured to use for each organic-carbon-containing feedstock a particular set of conditions including time duration, temperature profile, and the chemical content of pretreatment solution to at least initiate the dissolution of contaminates that would hinder creation of the plant cell wall passageways that allow intracellular water and intracellular water-soluble salts to pass outward from the plant cells; and a mastication chamber before the reaction chamber and configured to reduce particle size of the unprocessed organic-carbon-containing feedstock to less than 1 inch (2.5 cm) as the longest dimension. The section (b2) further comprises at least one rinsing subsection configured to flush at least some of the water-soluble salt from the porous organic-carbon-containing feedstock before it is passed to the compaction section. The reaction chamber is configured to operate at conditions predetermined for each unprocessed organic-carbon-containing feedstock to minimize the energy consumed to lead to a particular set of processed organic-carbon-containing feedstock properties, where: the section (b1) is configured to use conditions that comprise at least a solvent medium, time duration, temperature profile, and chemical content, and the conditions are tailored for each organic-carbon-containing feedstock; the section (b2) is at least configured to create porous organic-carbon-containing feedstock with decompression conditions tailored for each organic-carbon-containing feedstock that comprise at least pressure drop, temperature profile, and decompression duration to form porous organic-carbon-containing feedstock; and the section (b3) is configured to compress the porous organic-carbon-containing feedstock between the pressure plates at conditions particular to each organic-carbon-containing feedstock that include compaction pressure profile and compaction duration to form processed organic-carbon-containing feedstock. At least one pressure plate has a pattern that is adapted to compress each organic-carbon-containing feedstock with targeted results.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The pressure is removed within a time of less than 500 milliseconds. The process (P1) further comprises: prewashing the unprocessed organic-carbon-containing feedstock before it enters the reaction chamber with a particular set of conditions for each organic-carbon-containing feedstock that includes time duration, temperature profile, pressure profile and chemical content of pretreatment solution to at least initiate the dissolution of contaminates that hinder creation of the cell wall passageways for intracellular water and intracellular water-soluble salts to pass outward from the plant cells; masticating the unprocessed organic-carbon-containing feedstock into particles having a longest dimension of less than 1 inch (2.5 centimeters) before it enters the reaction chamber; and separating at least oils, waxes, and volatile organic compounds from the porous feedstock with solvents less polar than water. Preferred Components: The unprocessed organic-carbon-containing has a water-soluble salt content of at least 4000 mg/kg on a dry basis. The contaminants comprise resins, rosins, glue, creosote, and oils. The organic-carbon-containing feedstock comprises at least two types comprising a herbaceous plant material, a soft woody plant material, and a hard woody plant material, where each type passes in series through the reaction chamber, and the energy density of each type of plant material in the processed organic-carbon-containing feedstock is substantially the same, and is at least 17 MMBTU/ton (20 GJ/MT). The volatile plant fibril permeable fluid decompression comprises steam decompression.
