The present application relates to the technical field of slag resource processing, more particularly, it relates to a slag recycling secondary treatment process. It comprises the following steps: titanium-containing blast furnace slag recycling and processing, titanium-containing blast furnace slag resource processing, composite adsorbent preparation, resource secondary treatment and composite phase change heat storage material preparation. In the present application, through the resource processing of the titanium-containing blast furnace slag, the titanium-silicon composite matrix material and the mixture powder can be separated from the titanium-containing blast furnace slag, and the titanium-silicon composite matrix material and the mixture powder can be used for preparing the composite adsorbent and used as the matrix material of the composite phase change heat storage material respectively, so as to achieve the purpose of efficient resource utilization of the titanium-containing blast furnace slag and play the characteristics of each component in the titanium-containing blast furnace slag.

The invention discloses a method for preparing nitrogen-doped biochar based on one-step co-pyrolysis of thermosetting resin and biomass. The method comprises the following steps: uniformly mixing urea resin solid powder, biomass and an activating agent; placing the mixed material in inert atmosphere protection, and carrying out temperature programming to 500-800 DEG C to carry out co-pyrolysis reaction; after the pyrolysis is completed, cooling, washing and drying to obtain the carbon material. According to the invention, one-step co-pyrolysis of urea-formaldehyde resin and biomass is utilized, effective doping of nitrogen element is realized at a relatively low temperature, in-situ molding of the material is realized by utilizing the thermosetting characteristic of urea-formaldehyde resin, and a molded carbon material with good mechanical strength can be obtained without an additional binder; the alkalescent potassium salt is selected as the activating agent and is environment-friendly, the prepared carbon material has high specific surface area and ultrahigh microporosity, the CO2 adsorption capacity is remarkably improved, the process is simple, and the energy consumption is low.
