  • Patent number: 11633714
    Abstract: A preparation method for a combined modified straw active particulate carbon adsorption material and use of same. The preparation method for the combined modified straw active particulate carbon adsorption material comprises the following steps: 1) mixing straw powders, distilled water, a binder and a composite mineral, then pelletizing same, and then placing same in a tube furnace for pyrolysis to prepare straw particulate carbon; 2) introducing an inert gas into a modification reagent, adjusting the pH value combined and 3) soaking the straw particulate carbon into the combined modification solution for 30 min, and performing cleaning and drying, so as to obtain a combined modified straw active particulate carbon adsorption material. The combined modified straw active particulate carbon has a good adsorption effect on phosphate group in low-pollution water.

  • Patent number: 11306622
    Abstract: A coal-fired power generation system and a supercritical CO2 cycle system thereof are provided. The supercritical CO2 cycle system includes a compressor unit and a turbine unit. The turbine unit includes a preceding stage heater, a preceding stage turbine, a last stage heater and a last stage turbine successively connected in series. An exhaust port of at least one of compressors in the compressor unit is in communication with the turbine unit through a split flow pipe, and a communication position between the split flow pipe and the turbine unit is located downstream of a suction port of the preceding stage turbine. An auxiliary regenerator and an auxiliary heater are provided at the split flow pipe, and the auxiliary regenerator is located upstream of the auxiliary heater.

  • Publication number: 20210274727
    Abstract: A straw-based pot body blanket seedling growth substrate using straw fibres as a framework, utilising an enhancer, a retention aid and a wet strength agent as additives, and being prepared from composite decomposed livestock manure, perlite and vermiculite, the addition amount of the straw fibres being 60-70 v/v %, the addition amount of the decomposed livestock manure being 5-10 v/v %, the addition amount of the perlite being 5-10 v/v %, the addition amount of the vermiculite being 5-10 v/v %. The pot body blanket seedling growth substrate is suitable for cutting and easily implementing fully automated transplantation, is beneficial for root growth, shortens seeding growth periods, and increases seedling growth bed emergence rates. The pot body blanket seedling growth substrate may be applied to solanaceae seedling growth, and can also provide a block-shaped substrate for landscape flowers and plants in a three-dimensional arrangements.
