8751 results about "Hydrolysate" patented technology

Hydrolysate refers to any product of hydrolysis. Protein hydrolysate has special application in sports medicine because its consumption allows amino acids to be absorbed by the body more rapidly than intact proteins, thus maximizing nutrient delivery to muscle tissues. It is also used in the biotechnology industry as a supplement to cell cultures. In the December 2013 edition of The International Journal of Food Science and Technology, hydrolysate was shown to be rich in L-aspartic acid and the necessary minerals manganese and selenium...

Ethanol production with dilute acid hydrolysis using partially dried lignocellulosics

In a process for converting lingnocellulosic biomass to ethanol, the improvement of obtaining higher fermentable soluble sugar yields by drying acid impregnated biomass particles, comprising: a) feeding moist lignocellulosic biomass into an acid impregnator to render it acid-soaked and draining the acid-soaked biomass to about 30% to 35% by weight solids; b) dewatering the acid-soaked biomass by drying or centrifugation to prevent compaction of the biomass and arrive at about 40% to 60% by weight solids; c) subjecting the acid-impregnated biomass to a first-stage hydrolysis reactor at a temperature of from 130° C. to 220° C. and discharging formed hydrolysate into a flash tank at about 120° C. to 140° C. to hydrolyze most of the remaining soluble oligosaccharides to monomeric sugars, and flashing remaining hydrolysate to a second flash tank at a lower temperature than the first flash tank-the second flash tank serving as a feed surge tank for a counter-current extractor; d) washing the hydrolysate, adjusting the pH of the sugar extract to about 5, and recovering more than 95% of the soluble sugars in the first-stage hydrolysate slurry by a counter-current extractor; e) subjecting remaining washed-first stage solids of pretreated biomass to a second-stage acid and metal salt impregnator and dewatering by drying or centrifugation to prevent compaction of biomass to arrive at 40% to 60% by weight solids; f) subjecting the acid and metal salt-impregnated biomass to a second-stage hydrolysis reactor at a temperature from 190° C. to 240° C. and discharging formed hydrolysate into a flash tank, at about 120° C. to 140° C. to hydrolyze most of the remaining soluble oligosaccharides to monomeric sugars and flashing remaining hydrolysate to a second flash tank at a lower temperature than the first flash tank, the second flash tank serving as a feed surge tank for second-stage fementors; g) cooling pH-adjusted extract from the counter-current extractor, feeding the extract to a first-stage fermentor and air sparging the first-stage fermentor at a rate sufficient to promote enough yeast growth to compensate for loss through second-stage fermentors; h) pH adjusting second-stage hydrolysate slurry to 4.5, cooling the slurry and adding it into the top of the first fermentor of a two-fermentor train in the second stage fermentors, pumping broth from the bottom of the first stage fermentors to the second stage fermentors while the yeast is in the growth phase for a period sufficient to consume over 95% of fermentable sugars; and i) recovering ethanol.

Apparatus and Process for Production of Biogas

A process and an apparatus for the manufacture of biogas and a solids fraction from an organic waste feedstock is provided. The process involves thermal hydrolysis of the organic waste feedstock at a temperature from about 100 to about 220° C., a pressure from about 5 to about 20 bars, for a period of time from about 15 minutes to 4 hours, to produce a hydrolysate. The hydrolysate undergoes anaerobic digestion at a temperature from about 25 to 60° C., for a period of time from about 1 to 35 days to produce a biogas stream and a digestate. The digestate is separated into a solids fraction and a liquid fraction, and a portion of the solids fraction is recycled for further anaerobic digestion. The biogas stream, characterized as having a methane content from between 55 to 80% by volume, and the solids fraction, are recovered. The apparatus includes a receiving bin for receiving and supplying organic waste feedstock to a thermal hydrolysis reactor. The thermal hydrolysis reactor for processing the organic waste feedstock at a temperature from about 100 to about 220° C., a pressure from about 5 to about 20 bars, for a period of time from about 15 minutes to 4 hours to produce a hydrolysate. An anaerobic digester for processing the hydrolysate at a temperature from about 25 to 60° C., for a period of time from about 1 to 35 days to produce the biogas and a digestate, and a solids thickening tank for separating the digestate into the solid fraction, a liquid fraction and a secondary biogas fraction.

Method for extracting metal scandium and titanium from red mud

The invention relates to a method for extracting metal scandium and titanium from red mud; the method is used for extracting scandium and titanium from the red mud; the method takes the red mud which is produced through the sinter process of the high-grade ore two portion of clinker in alumina plant as the raw material; the hydrochloric acid with a concentration of 2 percent to 6 percent is used for leaching the calcium and sodium from the red mud to increase the content of the scandium and titanium in the red mud; and then the hydrochloric acid with a concentration of 16 percent to 22 percent is used for a second acid dipping of the red mud and the product of scandium oxide is obtained after the leaching liquid passes the processes of extraction, reverse extraction and baking; the hydrochloric acid with a concentration of 80 percent to 90 percent is used for a third acid dipping of the red mud after the second one and the leaching liquid is added with iron powder for reduction and then the temperature is reduced to crystallize and separate out iron in the pattern of FeSO<4>.7H<2>O; the acid liquid which contains titanium after the iron is removed is added with alkali and heated for hydrolysis; the product of titanium oxide is obtained after the hydrolysate is baked. The method is simple and easy to be carried out and most metal elements in the red mud can be recovered and the cost for processing the red mud is low, all of which are beneficial to the comprehensive utilization of the red mud.
