Method for preparing xylooligosaccharide from corncobs through microwave-assisted hydrothermal treatment

The invention discloses a method for preparing xylooligosaccharide from corncobs through microwave-assisted hydrothermal treatment. The xylooligosaccharide is a functional glycopolymer formed by combining 2-6 xylose molecules by beta-1,4 glucosidic bonding; the method of the microwave-assisted hydrothermal treatment is that water is taken as a reaction solvent, and a complex three-dimensional network structure of cell walls of the corncobs is efficiently and rapidly broken by virtue of a microwave-assisted technology, so that hemicelluloses are dissolved out and subjected to hydrolysis reaction to generate the xylooligosaccharide; the specific steps for preparing xylooligosaccharide from the corncobs through the microwave-assisted hydrothermal treatment are as follows: crushing the corncobs into small granules, extracting by an organic solvent, filtering, washing by purified water, drying, and then carrying out ball-milling; adding a sample subjected to the ball-milling and the water in a reaction kettle, carrying out ultrasonic treatment and reacting in a microwave; and concluding the reaction, cooling, carrying out suction filtration to obtain filtrate, distilling and concentrating the filtrate, and carrying out freeze-drying to obtain the xylooligosaccharide. The method for preparing xylooligosaccharide from the corncobs through the microwave-assisted hydrothermal treatment has the advantages of being rapid, efficient, environmentally friendly, and the like.

Distributed and centralized collaborative micro-grid group scheduling method

The invention discloses a distributed and centralized collaborative micro-grid group scheduling method. The method comprises the following steps: acquiring day-ahead prediction data of photovoltaic and load in each unit of a park micro-grid group; constructing a park micro-grid group plan scheduling model, and performing solving to obtain a plan scheduling result of the micro-grid group; calculating the difference between the real-time operation state data of each device and each load of the microgrid group in the park and the planned scheduling result of the microgrid group to obtain the overall real-time net electric power deviation of the park; calculating real-time net electric power deviation shared by each unit of the park, constructing a real-time optimization scheduling model of each unit, and solving the real-time optimization scheduling model of each unit to obtain a real-time power reference value of each unit microgrid of the park; and issuing the solved real-time power reference value to each micro-grid unit to complete single-time optimal scheduling of the micro-grid group, and repeatedly executing the steps in a running day to complete daily running scheduling of the micro-grid group. According to the method, the difference benefit maximization of the whole micro-grid group is achieved, and the economic requirements of global development of the current power grid are met.

Catalytic cracking method for processing heavy oil, and apparatus thereof

ActiveCN102925207BAdequate responseAfter the reaction, the catalyst is fully mixedHydrocarbon oils treatmentCycloneCyclonic separation
The invention relates to a catalytic cracking method for processing heavy oil, and an apparatus thereof. The apparatus comprises a primary riser reactor, an auxiliary riser reactor, a gas-solid separation system and a regeneration device, the upper portion of the auxiliary riser is communicated with the middle and upper portion of the primary riser, the central axes of the primary riser and the auxiliary riser are not in a same plane, and a distance between the central axes of the primary riser and the auxiliary riser is greater than zero and less than the radius of the primary riser. An auxiliary riser oil gas agent undergoes simple cyclone separation when the oil gas agent enters the primary riser, an oil gas enters a settlement device from the upper portion of the primary riser, and a catalyst descends along the inner wall of the primary riser and is mixed with a catalyst which has reacted with a poor-quality raw material in the primary riser, thereby the catalyst which has reacted with the high-quality raw material and the catalyst which has reacted with the poor-quality raw material are fully mixed. The high temperature and the high activity of the former catalyst are utilized to make the oil gas carried by the latter catalyst fully react, so the light oil yield is improved by 2.0%, the liquid yield is improved by 2.5%, and the dry gas and coke yields are reduced by 2.2% respectively.

Method for cultivating catfish in rice field

InactiveCN112106700AImproving the Environment for Catfish BreedingPromote selective growthClimate change adaptationPisciculture and aquariaEutrophicationNutrition
The invention relates to the technical field of modern agricultural cultivation, and discloses a method for cultivating catfish in a rice field. The method ensures the maximum supply of nutrition in the rice growth period by intervening the element content of rice field cultivation water in the rice growth process, improves the catfish cultivation environment, and promotes the preferred growth ofthe catfish, thereby enhancing the yield and quality of the catfish. By means of the cultivation mode, a whole rice field system has high self-purification capacity, benign growth and reproduction oforganisms in water are kept, the water environment is stable, the water changing frequency is remarkably reduced, the cost is reduced, meanwhile, cultivation losses caused by water quality pollution are avoided, mutual utilization of metabolites of rice and catfish is achieved, and the dynamic balance of a rice culture system is realized; and adverse effects of eutrophication on catfish cultivation are reduced, cost investment can be reduced, catfish cultivation benefits are increased, the problems of low catfish quality, poor benefits and large pollution in existing rice field cultivation aresolved, and the yield can be increased on the premise that catfish cultivation quality is guaranteed.
