摘要:
The present invention concerns a process for producing synthetic coal and aqueous liquid plant fertilizing solution products from a fermentation residue such as is left over from the corn based process of producing ethanol. The synthetic coal has a high heat value commensurate with naturally occurring coals and is lower in ash and sulfur content and thus has value as a clean burning energy source. The aqueous fertilizer includes commercially useful amounts of phosphorous, potassium and nitrogen in solution. The process of the invention is also energy efficient in that the products produced thereby involve the use of substantially less energy as compared to the traditional methods of processing fermentation residues in the corn based ethanol production industry.

The present invention concerns low energy requiring methods for processing low cellulosic biomass materials into oil, char and liquid components. One method comprises the steps of subjecting the biomass to hydrothermal carbonization under specified reaction conditions for producing a combined char and oil fraction as well as an aqueous fraction, separating the combined oil and char fraction from the aqueous fraction by filtration; separating the combined oil and char fraction into individual oil and char fractions using an organic solvent for forming an oil depleted char fraction and a liquid oil and solvent solution, and separating the liquid oil and solvent solution into individual oil and solvent fractions by distillation.
摘要:
Synthetic coal, methods of producing synthetic coal, produced from fermentation residue, such as the residue from ethanol production, by subjecting the fermentation residue to hydrothermal carbonization in an aqueous solution at a temperature and a pressure sufficient to form a synthetic coal solid and a liquid component. The solid synthetic coal component has a low ash content and may be used as a carbon source for energy production, such as for combustive thermal energy generation, or for gassification for the production of synthesis gas.

Algae-derived synthetic coal and filtrates. The invention described herein provides an algae-derived synthetic coal product and filtrates and process for preparing the same using an improved hydrothermal carbonization process. The synthetic coal product is similar to natural bituminous coal in terms of percent carbon content and energy equivalency while at the same time containing relatively low levels of sulfur and contaminant heavy metals. Unlike natural coal and other fossil fuels, because the carbon of the biomass is formed through photosynthesis, carbon dioxide formed during combustion is a “carbon neutral” event with little or no “new” carbon dioxide being added to the earth's atmosphere. The algae-derived filtrates contain useful constituents.

摘要:
The invention herein describe a novel process for producing a novel synthetic coal product from fermentation residues, such as, the waste materials from fermentation based ethanol production. The fermentation residue is subject to a hydrothermal carbonization process in an aqueous solution at a temperature and at a pressure sufficient to form a synthetic coal solid and a liquid component. This process does not require drying of the fermentation residue which provides for a more energy efficient method of processing thereof. The synthetic coal solid has a high heat content combustive material. The liquid component has nutrient value so that it can be recycled thereby permitting the sustainable recycling of such nutrients and the water in which those nutrients are dissolved.

A process is provided for improving the reliability of sterilization of canned viscous food products by ensuring the proper amount and rate of rotation of cans during heat processing. Improvement in controlling the lethality of microorganisms can be accomplished. The method involves intervallically monitoring the rotation of the canned food in the processing equipment and utilizing the obtained rotation information to correct processing conditions to ensure commercial sterility.
摘要:
The food material to be processed is alternately transferred from two sources to an elongated treating chamber. The apparatus for carrying out the method includes rotary valve means employing two pocket areas, each pocket area including a plurality of pockets with each pair of diametrically located pockets having an interconnecting passage. The pockets of one area are angularly displaced or out-of-phase with the pockets of the other area. Owing to the out-of-phase relationship, the food material to be processed is alternately received by one pocket of one area, then by the next pocket of the other area and so on through each revolution of the valve means in which the pockets are contained, the material being discharged in the same out-of-phase relationship through the interconnecting passages and diametrically disposed pockets into the inlet of a pressurized elongated treating chamber.

A method is provided for preparing a breading material suitable for use in coating various meat and vegetable products. A mixture including flour, yeast, whey together with various other materials is fed into an elongated treating chamber under pressure. The chamber has an inlet at one end and an outlet at the other end. A flow of hot gaseous fluid from the direction of the inlet propels the mixture through the elongated chamber and out of the outlet.
