Abstract: A method for removal of selected substances from carbonaceous material by use of a solvent is provided comprising: (a) introducing the carbonaceous material containing the selected substances into an extraction zone to form a bed; (b) introducing a gas which at a given pressure liquifies at a higher temperature than the solvent, the introduction being made under a pressure and at a temperature to cause the temperature and pressure of the extraction zone to be sufficient to cause the solvent to liquify when the solvent is introduced to the extraction zone; (c) introducing into the extraction zone the solvent capable of extracting the selected substance; (d) passing the solvent through the bed of carbonaceous material to extract the substances from the material; (e) removing the resulting substance/solvent mixture from the extraction zone to a separation zone under conditions which will maintain the solvent in liquid form as it is passed through the bed of carbonaceous material and out of the extraction zone to

Abstract: A process for removing fats and oils from prepared animal-derived fried-derived food products, particularly fried meat, poultry, and fish products. The method involves treating the animal-derived fried-derived food product with a normally gaseous solvent at effective temperatures and pressures.

Abstract: In a solvent extraction process for the extraction of an extractive from extractive-containing material employing in an extraction zone operating under extraction conditions a process solvent, whereby a miscella comprising a portion of the process solvent and a portion of the extractive, and an extractive-depleted substrate is formed, the improvement to which comprises: (a) removing the miscella from the extraction zone under extraction conditions, (b) filtering the miscella by use of a microfiltration, an ultrafiltration, a nanofiltration, or a reverse osmosis membrane, under conditions which achieve a differential pressure across said membrane, to separate the solvent in the miscella from the extractive in the miscella, and (c) recycling under extraction conditions at least a portion of the separated solvent to the extraction zone.

Abstract: A process for recovering edible oil and bleaching clay from an edible oil-bleaching clay waste stream and for recovering edible oil and nickel catalyst from a hydrogenated edible oil-nickel catalyst-filter aid waste stream; the recovered bleaching clay may be reused directly and the recovered nickel catalyst and filter aid mixture is pelletized for metallurgical nickel recovery.

Abstract: An improved low temperature process for extracting oil from oil-bearing materials by extracting the oil-bearing material in an extraction zone with a normally gaseous solvent selected from propane, butane, and mixtures thereof. As the resulting solvent/oil mixture is passed through the bed of extracted oil-bearing material, from the extraction zone, and to a separation zone, it is done so under conditions that will maintain the solvent in liquid form. The resulting extracted materials have substantially more of their protein and vitamin value intact when compared with similar materials extracted by more conventional high temperature methods. The present process is also a lower energy consuming process than more conventional, extractive processes.

Abstract: The invention relates to a process for extracting oil from an oil bearing plant material with the use of a solvent suitable for dissolving the oil in the plant material. Grounded plant material is deposited into a reactor vessel, and vacuum is created in the reactor vessel. Liquid solvent is introduced into the reactor vessel and allowed to contact the plant material for a time sufficient to dissolve oil from the plant material, while the temperature in the reactor vessel is maintained at a level which prevents denaturing of constituent components of the plant oil and the plant material. Additional solvent vapors are introduced into the bottom of the reactor to cause mixing of the plant material and the solvent and separate fine particulate matter from heavier particles. Pressurized heated solvent vapors are introduced into the top of the reactor vessel while the liquid solvent and oil combination is being removed from the bottom of the reactor vessel through filters.

Abstract: The present invention provides anti-tumor neutral lipids of the endosperm of Job's tears (Coix lachrymajobi), a method to extract and refine it from the endosperm of Job's tears and a pharmaceutical composition containing the neutral lipids. The neutral lipids of the endosperm of Job's Tears and its pharmaceutical composition are indicated for anti-tumor effect, enhancement of immunity and protection from many diseases.

Abstract: An extraction process comprising contracting a material to be extracted with an extracting fluid at elevated pressure within a defined space, and separating the extracted fluid and extract as a mass, from the extracted material while reducing the volume of the defined space and while maintaining the elevated pressure within the defined space. Apparatus for carrying out the process is adapted to separate the extracting fluid and the extract, as a mass, from the extracted material, while maintaining elevated pressure and reducing the volume as the point of separation.

Abstract: A vegetable oil process and assembly is disclosed for extracting oil from an oil bearing material such as soybean, corn and the like. The process comprises adding at least one reagent to the oil bearing material to form a slurry mixture. The slurry is heated at a preselected temperature for a preselected period of time preferably under a partial vacuum. This processing reduces the phospholipid and trace metal content in the oil extracted from the oil heating material. The oil product produced is light in color, shows no turbidity and exhibits minimal amount of phosphorus, calcium, magnesium and iron. The oil is ready for physical refining.

Abstract: The process for recovering vegetable oleaginous substances from oil-containing natural substances comprises a series of continuous combined pressing and extraction steps to increase and simultaneously to guarantee a high quality product for different kinds of natural substance starting materials. This is accomplished by subjecting the natural substances, conditioned and comminuted if necessary, after mixing with a solvent phase containing some oil to an intensive processing, mixing and extraction in the shear field of at least one rotor-stator unit and subsequently feeding the resulting liquid phase, through a filter if necessary, to a distillation column. The solid phase is extracted in successive stages until a residual oil content of 1% is reached and the solvent is fed back to a solid phase in a counterflow. The process as defined in my invention is universally applicable to all fat and oil-containing natural substances using suitable fluid extraction means.
