Abstract: A bio-oil light fraction-based bread-shaped porous activated carbon, a method for preparing the same and use thereof are provided. A light fraction prepared by fast pyrolysis of a biomass coupled with molecular distillation is selected as a precursor; an activator is directly mixed with the light fraction and stirred to obtain a homogeneous liquid; then, the homogeneous liquid is subjected to one-step carbonization and activation at a two-stage temperature in an inert atmosphere; after the activation, the obtained solid was washed and filtered, the activator reaction products and impurities are removed, and then dried to obtain the activated carbon used as an electrode carbon material of a supercapacitor. The method fully utilizes the rich micromolecule compounds such as water, acids, ketones, aldehydes, monophenols and the like in the obtained light fraction, and the micromolecule compounds and water can interact with the activator.

Abstract: Disclosed are a catalyst for synergistic control of oxynitride and mercury and a method for preparing the same. The catalyst includes the following components by mass percentage: a carrier: TiO2 72%-98.6%, active components: V2O5 0.1%-5%, WO3 1%-10%, Cr2O3 0.1%-5% and Nb2O5 0.1%-5%, and a co-catalyst of 0.1%-3%. The present invention can be used for reducing the oxynitrides in a flue gas, meanwhile oxidizing zero-valent mercury into bivalent mercury and then controlling the reactions, has relatively high denitration performance and also has high mercury oxidation performance; compared with current commercial SCR catalysts, the mercury oxidation rate of the catalyst is improved to a great extent, which can adapt to the requirements for mercury removal in China's coal-fired power plants, the conversion rate of SO2/SO3 is relatively low, and the catalyst has a better anti-poisoning ability, and is a new catalyst with a low cost and high performance.

Abstract: The present invention provides a one-dimensional global rainbow measurement device and a measurement method. The measurement device comprises three parts, i.e., a laser emission unit, a signal collection unit and a signal processing unit. The laser emission unit is modulated to be a light sheet by a laser beam emitted by a laser, and configured to irradiate droplets in a spray field to generate rainbow signals. The signal collection unit is configured to separately image, by an optical system unit, the rainbow signals at measurement points of different height onto different row pixels of a CCD signal collector. The signal processing unit is configured to convert the received rainbow signals and process by a computer the rainbow signals in a form of data to obtain the measured values.
