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.

Feed for early weaned suckling pigs

The invention relates to a feed for early weaned piglets, which belongs to the field of the feed. Main ingredients of the feed comprise expanded corn, full-fat soybean, fat powder, steam fish meal, acidified whey powder, fermented soybean meal, a complex enzyme preparation, a micro-ecological preparation, amino acids, complex vitamins, complex trace elements and the like. The digestive physiological characteristics of the weaned piglets are fully considered on the selection and the processing of raw materials, thereby greatly improving the palatability and the digestion rate of the feed; simultaneously, through the synergistic compatibility of an egg yolk antibody, lactein, sodium humate and the complex micro-ecological preparation, the diarrhea rate of the weaned piglets is reduced, the effects are superior to those of adding antibiotics into the feed, and the feed is the green, environmentally-friendly and nuisanceless feed. An animal feeding experiment proves that the feeding effects are ideal, the palatability is good, the piglets after weaning are high in average feed intake, fast in daily weight gain and low in diarrhea rate, and the feed has a good promoting effect for growth and health conditions of the weaned piglets and can meet the demands of most of raisers at present.

Efficient methane-generating pit using poultry excrement and methane generation process

The invention relates to a methane-generating pit using poultry excrement, which is integrally horizontally placed under the water plane. Partition walls are arranged in the middle of the methane-generating pit for dividing the whole methane-generating pit into a plurality of unit methane-generating pits, and medium channels arranged on the partition walls are communicated with each other. An annular fermentation tank is arranged above the periphery of the methane-generating pit, a plurality of superconductive heat pipes are arranged on the inner side of the annular fermentation tank, and the superconductive heat pipes are inserted into the methane-generating pit. A material inlet and a material outlet are respectively arranged at two ends of the methane-generating pit and under the unit methane-generating pits at two ends of the methane-generating pit, a methane collector is arranged above each unit methane-generating pit, and the methane collectors are directly communicated with a gas storage tank through pipelines. The methane-generating pit has the advantages of being high in material concentration, integrating material inlet, deslagging, methane generating, stirring, temperature controlling, regulating and the like, being high in mechanization degree, large in treating quantity, fast in digesting rate and the like and can meet requirements for scale production, and concentration of inlet materials of a continuous methane-generating pit can reach about 15%.

Composite biological feed additive agent for fattening early weaning mutton sheep

The invention relates to an early weaning meat sheep fattening compound biological feed additive, which belongs to the technical field of animals feeding by feed. The feed additive comprises prebiotics consisting of candida utilis, bacillus subtilis and a lactobacillus plantarum microbial agent, non-starch polysaccharide enzyme containing cellulase, xylanase, beta-dextranase, beta-mannase and pectinase and a yeast culture formed by using saccharomyces cerevisiae to completely ferment bean pulp. The additive is specially used for fattening period ration of the early weaning(the weaning lunar age is less than or equal to 2 ages of the moon) meat sheep, and the adding percentage for the full-mixing ration of the fast-fattening meat sheep in 3 to 5 ages of the moon is 1 percent. The additive can provide functional nutrients such as digestive enzyme, B group vitamins and growth promoting factors, and the like which are inadequately produced and insufficient for the early weaning baby sheep and simultaneously contains probiotics for adjusting the micro-ecological environment in intestinal canals, thereby improving the immunity and the healthy level of the baby meat sheep; and after weaning, the daily gaining in weight is more than 10 percent in the prior period and later period of fattening, and the economic benefits are obviously improved.
