The invention relates to a method for extracting oil from microalgae by utilizing ionic liquid, which comprises the following steps of: 1) preparing functionalized ionic liquid; 2) adding a certain quantity of microalgae into the ionic liquid and magnetically agitating through heating to dissolve the microalgae; 3) extracting oil in an ionic liquid mixture by using an organic solvent; and 4) adding a certain quantity of water into an ionic liquid phase after the oil is extracted, removing a water phase through evaporation, realizing the regeneration of the ionic liquid and reusing the ionic liquid. According to the method, the ionic liquid is utilized to dissolve the microalgae so as to extract the oil, almost has no vapor pressure and has the characteristics of greenness, environment friendliness and the designability; the cell wall of a microalgae can be remarkably damaged to release oil in a microalgae cell or on the cell wall; the oil is easily separated from the ionic liquid, so that the extraction rate of the oil can be remarkably improved; and the ionic liquid can be recycled through a water dilution method. The method can become a new process for microalgae oil extraction.

The invention discloses a method for preparing a multi-stage pore Y molecular sieve, which relates to the field of molecular sieve synthesis; specifically, it comprises the steps of: pre-preparing a Y-type molecular sieve with a silicon-aluminum ratio of 4-6:1 in an alkaline solution at 20-150°C. Processing; under anhydrous conditions, use an inert gas to carry SiCl 4 and / or SiHCl 3 Steam reacts with pretreated molecular sieves to dealuminate and replenish silicon; then treat with ammonium ion solution at 60-120°C for 0.1-3h; then roast, wash, and dry to finally obtain multi-stage channel Y-type molecular sieves; this invention adopts alkali treatment and chemical The combination of the method and method does not destroy the structure of the molecular sieve. The obtained molecular sieve has a high specific surface area and crystallinity. The prepared multi-stage channel Y molecular sieve has a silicon-aluminum ratio of 20-160; the generated secondary pores are interconnected, and the channels The diameter can be adjusted between 2-50μm according to the alkali treatment conditions; the relative crystallinity of molecular sieves is >70%.

A process and a plant for the thermal abatement of foul air containing malodorous substances. A flow of foul air containing malodorous substances as combustive air is fed into the combustion chamber of a unit for production and recovery of energy, and a flow of exhaust gas is obtained. The flow of exhaust gas is fed into a scrubber for the abatement of polluting substances, whereby the scrubber uses water for the washing of the flow of exhaust gas, producing a flow of low-temperature purified gas and a heated washing liquid. The heated washing liquid is conveyed to at least one heating jacket of a storage tank for the biological treatment of sewage of the aforementioned purification plant.

A pore-protecting drying method for porous materials relates to porous materials. Mix the displacing agent, pore-protecting agent and hydrous porous material gel in a drying kettle, heat the drying kettle to boiling, and use a water separator to separate the water, and continue heating after most of the water in the hydrous porous material can be replaced , to obtain a dry solid product. The used displacing agent is cheap, easy to recycle, simple and easy to control the process, mild operating conditions; the prepared porous material has excellent performance. On the basis of conventional low-boiling azeotropic distillation, a small amount of pore-preserving agent is added to achieve pore-protecting drying, so as to obtain high-pore-volume silica and other porous materials efficiently and economically.

The invention discloses a preparing and collecting method for starch particles. The preparing and collecting method comprises the steps that starch is subjected to superfine grinding and then prepared into a starch solution with a certain concentration; the starch solution is subjected to homogenization with a high-pressure homogenizing machine and treated with a high-speed fluidizing device and then passes through a super centrifuge, centrifugal separation is carried out at different rotating speeds, and starch particles of different sizes are obtained; finally, the starch solution containing starch particles of different sizes is led into an electrophoresis tank, a cationic surfactant is added, polar plates in different shapes or with specific patterns are arranged, and starch particles assembled in a patterned mode in different sizes are obtained on a collector. According to the preparing method, the starch particles obtained after superfine grinding in combination with high-speed fluidizing are obvious in damage of crystalline structures, active groups are fully exposed, the action between the starch particles and the cationic surfactant is easier, and the collected starch particles with different patterns and different sizes are formed at a time and uniform and can be widely applied in the fields of preparing functional starch films, patterned paper and the like.
