The invention relates to a preparation method of coumarone resin for high-carbon-residue carbon fiber. The light components are removed from ethylene tar to obtain heavy tar; the heavy tar is subjected to high-temperature cracking in a cracking furnace; and the heavy oil is polymerized in a polymerization kettle , polymerized at 280‑300°C for 4 to 7 hours; the product obtained from the polymerization was subjected to falling film flash evaporation, concentrated and granulated to obtain coumarone resin. The coumarone resin produced by the invention has high utilization rate of recombinant composition, high carbon residue in the resin, basically unchanged content of toluene and quinoline insolubles, and small ash content, and is suitable as a raw material for processing carbon fibers.

The invention relates to a cell pretreatment method for electrochemical detection, which relates to a cell pretreatment method for electrochemical detection. The purpose of the present invention is to solve the problem that the electroactive substances released by the existing cell pretreatment technology are not complete enough, so that the change of cell activity cannot be truly reflected. Culture in an incubator with a volume concentration of 5%, then remove the medium, then add hypotonic lysate to adjust the cell concentration, and then lyse in a water bath to complete. The cell in-situ compound lysis of the present invention realizes the complete rupture of the cell membrane, greatly enhances the electrochemical signal, and simplifies the processing, which not only strengthens the electrochemical detection signal, but more importantly, the electrochemical detection result more accurately reflects the intracellular Reality of electroactive species content. The invention is applied in the field of biological analysis.

This invention relates to a grate assembly apparatus for straw gasifier. The grate assembly apparatus comprises: an automatic transmission device and a cone-shaped grate. The cone-shaped grate is composed of a cone and a plane. Both ends of the plane comprise a hole. The rotary grate has a spherical lamellar structure, and both ends of the rotary axis on it stop run through the holes and are connected with the cone-shaped grate. A wind-shielding cap is set at the lower part of the cone-shaped grate, which is barrel shaped. The contact parts of the wind-shielding cap and the cone-shaped grate have 12-20 deg. angles, and are tightly fixed. One end of the rotary axis runs through the wind-shielding cap, and is connected with one end of the transmission shaft of the automatic transmission device. The grate assembly apparatus has such advantages as high coal tar cracking degree, high gas productivity, simple structure, and no deformation after a long time use.

The invention discloses an auxiliary agent for biomass treatment and a biomass gasification treatment method. The auxiliary agent includes component A, component B and component C; wherein, the component A includes Lewis acid, and any One or more of selected organic acids and protonic acids, the component B is a salt of IA, IIA, IIIA group metal and ammonium, and the component C is one of manganese acetate, manganese sulfate, manganese nitrate species or several. The gasification treatment method is to react the biomass raw material and the auxiliary agent after mixing, and obtain the volatile components and bio-semi-coke after the reaction; the solid-phase materials and bio-semi-coke obtained after the gas-solid separation of the volatile components are respectively fed into the After the biocoke microwave gasification reactor reacts, crude synthesis gas and activated carbon are obtained; the synthesis gas obtained after the gas-solid separation of the crude synthesis gas enters the purification reactor for treatment to obtain purified synthesis gas. The biomass gasification treatment method and system can increase the synthesis gas yield, and the tar content in the obtained synthesis gas product is low.

The invention discloses a method for simultaneously extracting total DNA and RNA from compost, which comprises the following steps of: adding corrosion removal buffer solution into a compost sample, shaking and uniformly mixing the solution and the compost, standing the mixture, and centrifuging the suspension; repeating the operation till the centrifuged supernatant is clarified; grinding the sample after corrosion removal by using liquid nitrogen till the sample is powdery, then placing the powdery sample in cracking solution, shaking and uniformly mixing the sample and the solution, putting the mixture in an ice bath, and centrifuging the mixture; taking the cracked supernatant, adding sodium acetate and extraction buffer solution into the supernatant, and centrifuging the mixture after shaking; adding chloroform-isoamylol into the extracted upper aqueous phase, and centrifuging the mixture after shaking; adding isopropanol into the mixture to settle RNA, and washing, drying and dissolving the settled RNA to obtain purified RNA; and adding Tris alkali solution into the extracted organic phase, adding chloroform-isoamylol into the centrifuged upper aqueous phase, centrifuging the mixture, then adding sodium acetate and anhydrous ethanol into the mixture to settle DNA, and washing and dissolving the mixture to obtain purified DNA. The method has the advantages of large yield,good quality, low cost and the like.
