Abstract
Systems and methods for producing processed organic-carbon-containing feedstock from an unprocessed carbon-containing feedstock are described. Unprocessed feedstock is introduced into and transported through at least one reaction chamber. The reaction chamber is configured for each feedstock to produce processed feedstock having a water-soluble salt reduction of at least 60 percent from that of unprocessed organic-carbon-containing feedstock and a water content of less than 20 percent.
Claims19
A system for removing water and water-soluble salts from an organic-carbon-containing feedstock, comprising:
- a. a transmission device configured to convey into a reaction chamber unprocessed organic-carbon-containing feedstock comprising free water, intercellular water, intracellular water, intracellular water-soluble salts, and at least some plant cells comprising cell walls that include lignin, hemicellulose, and microfibrils within fibrils;
- b. at least one reaction chamber comprising at least one entrance passageway, at least one exit passageway for fluid, at least one exit passageway for processed organic-carbon-containing feedstock, and at least three sections, the sections comprising,
- i. a wet fibril disruption section configured to interact with at least some of the lignin and hemicellulose between the fibrils to make at least some regions of the cell wall more susceptible to outflow by water-soluble salts,
- ii. a vapor explosion section in communication with the wet fibril disruption section and at least configured to volatilize plant fibril permeable fluid through rapid decompression to penetrate the more susceptible regions of the cell wall so as to create a porous organic-carbon-containing feedstock with plant cell wall passageways for intracellular water and intracellular water-soluble salts to pass from the plant cell, and
- iii. a compaction section in communication with the vapor explosion section and configured to compress the porous organic-carbon-containing feedstock between pressure plates configured to minimize formation of water-impermeable felt so as to permit the escape of intracellular water and intracellular water-soluble salt from the reaction chamber fluid exit passageway and to create processed organic-carbon-containing feedstock that passes out through its reaction chamber exit passageway;
- and
- c. a collection device in communication with the reaction chamber and configured to gather the processed organic-carbon-containing feedstock having a water content of less than 20% by weight and a water-soluble salt content that is decreased by at least 60% on a dry basis from that of the unprocessed organic-carbon-containing feedstock.
A process for removing water and water-soluble salts from organic-carbon-containing feedstock, comprising the steps of:
- a. inputting into a reaction chamber unprocessed organic-carbon-containing feedstock comprising free water, intercellular water, intracellular water, intracellular water-soluble salts, and at least some plant cells comprising cell walls that include lignin, hemicellulose, and microfibrils within fibrils;
- b. exposing the feedstock to hot solvent under pressure for a time at conditions specific to the feedstock to make some regions of the cell walls comprising crystallized cellulosic fibrils, lignin, and hemicellulose more able to be penetrable by water-soluble salts without dissolving more than 25 percent of the lignin and hemicellulose;
- c. removing the pressure so as to penetrate the more penetrable regions to create porous feedstock with open pores in the plant cell walls;
- and
- d. pressing the porous feedstock with conditions that include an adjustable compaction pressure versus time profile and compaction time duration, and between pressure plates configured to prevent felt from forming and blocking escape from the reaction chamber of intracellular and intercellular water, and intracellular water-soluble salts, and to create processed organic-carbon-containing feedstock that has a water content of less than 20 wt % and a water-soluble salt content that is decreased by at least 60 wt % on a dry basis from that of unprocessed organic-carbon-containing feedstock.
