Abstract: Disclosed are a sesquiterpene derivative and a use of the same in preparation of a medicament for treating hepatitis B diseases. The sesquiterpene derivative has the effects of down-regulating the hepatocyte nuclear factor 4α (HNF-4α) and significantly inhibiting the hepatitis B virus, and can be used for preventing and/or treating and/or assisting in the treatment of liver system diseases and symptoms caused by the hepatitis B virus, and can be used as a hepatic protective agent. In addition, the synthetic sesquiterpene derivative can also be used for preventing or treating viral infectious diseases and conditions resulting from the influenza virus, coxsackievirus, herpes simplex virus, etc. Also involved is the preparation of the synthetic sesquiterpene derivative, which acts as a raw material, in clinically acceptable pharmaceutical formulations, such as oral dosage forms such as tablets, capsules and drop pills or non-oral dosage forms such as inhalants and injections.

Abstract: A method for comprehensively processing noble lead provided and utilizes two instances of vacuum distillation to realize an open circuit of arsenic, lead, antimony and bismuth and the high-efficiency enrichment of precious metals of gold and silver, and can obtain elemental arsenic, a lead-bismuth-antimony alloy, a silver alloy and a copper alloy, respectively. The lead-bismuth-antimony alloy, the silver alloy and the copper alloy are processed by oxidation refining, electrorefining and chlorination refining to obtain refined lead, refined antimony, antimony trioxide, electrolytic silver and electrolytic copper, and to realize gold enrichment. The entire process has advantages of high metal direct yield, low energy consumption, short flow chart, simple equipment, etc., and vacuum distillation belongs to a physical process in which the alloy can be separated only by means of the difference in saturated vapor pressure between the metals, without generation of wastewater, waste gas and waste residue.

Abstract: The invention discloses a method for simultaneously removing SO2 and NOx in flue gas: uniformly mixing a water-soluble ruthenium salt with ammonia water to obtain an aqueous solution of a ruthenium-amine complex; subjecting the flue gas and the aqueous solution of the ruthenium-amine complex to a countercurrent contact reaction under the temperature of 5-60° C., pH of 7.5-12 to obtain a solution A and purified gas; discharging the solution A of the step (2) into a crystallization tank to crystallize and separate an ammonium salt to obtain a solution B, returning the solution B to replace the aqueous solution of the ruthenium-amine complex. The invention utilizes the ruthenium-amine complex having a strong capability of complexing with NO as well as residual oxygen in the flue gas to carry out liquid phase catalytic oxidation to convert the NOx into ammonium nitrate, the removal efficiency of the NOx and the SO2 is high.

Abstract: The invention involves a vibrating inclined plate box settlement separator, which is used for the liquid-solid separation, particularly applicable to high-efficiency settling concentration and separation of solid particles from liquid or water. The separator consists of an upper box and a lower tapered hopper. The upper box and the lower tapered hopper are connected securely to each other and sealed. The upper box is a rectangular or square steel-structured box with two supporting platforms on both of its sides, on which several spring assemblies are installed. The inclined plate box modules which can independently vibrate are installed on the spring assemblies, The feed box is placed on top of or inside the upper box. An overflow collect chute is welded on the side of the box frame opposite to the feed box.
