This invention discloses a covalent organic framework material for selective solid-phase adsorption and separation, its preparation method, and its applications. The material is prepared by polycondensation reaction of electron-deficient triazine rings with short-chain linkers such as hydrazine hydrate, forming a layered structure with a high specific surface area of ​​602 m² / g and a concentrated pore size of 2.0 nm to 3.0 nm. This structure exhibits high adsorption capacity (up to 1.0 mg / g), rapid adsorption kinetics, and excellent selectivity for PAHs in organic solutions through strong π-π interactions and pore confinement effects. The preparation process is simple and the conditions are mild. The material has good thermal stability (>300℃), and its performance retention rate is higher than 92% after 5 cycles. When applied to the solid-phase adsorption of PAHs in petroleum products such as lubricating oil and white oil, it effectively eliminates matrix interference, allowing direct analysis without complex purification steps after adsorption. This overcomes the limitations of traditional materials such as silica gel and activated carbon, which have weak adsorption capacity and require cumbersome post-treatment, providing a new high-performance adsorption material solution for the efficient detection of trace PAHs in petroleum products.

Embodiments described herein are directed to methods and systems for treating wastewater or storm water using vermifiltration. The wastewater can come from various sources, such as agricultural sources, municipal and industrial sources, wineries, the dairy industry, and many others. The systems can include vermicomposting beds that are capable of removing high amounts of contaminants, pollutants, and / or toxic substances from wastewater. The wastewater may be applied to vermicomposting beds, for example, by an irrigation system. The irrigation system may provide, for example, improved bed coverage and more even saturation. The vermicomposting beds can remove various harmful substances from the wastewater, such as petroleum products; industrial chemicals; heavy metals (e.g., lead, mercury, cadmium, arsenic); pesticides (e.g., atrazine, chlorpyrifos); and organic compounds (e.g., phenols, polycyclic aromatic hydrocarbons (“PAHs”), polychlorinated biphenyls (“PCBs”)).

This invention relates to a coupled system for SOEC hydrogen production and petroleum hydrotreating, comprising an SOEC hydrogen production unit and a petroleum hydrotreating unit. In the SOEC hydrogen production unit, pure water is vaporized in a steam generator to form steam, which is then electrolyzed in a fuel cell stack module to generate hydrogen. The mixture of hydrogen and steam is passed through a high-temperature heat exchanger on the hydrogen side to recover waste heat and preheat the steam. The separated hydrogen is then separated into reactive hydrogen and protective hydrogen by a booster compressor. The protective hydrogen is mixed with the steam and recycled. In the petroleum hydrotreating unit, the reactive hydrogen is mixed with the petroleum product to be hydrotreated and undergoes two heat exchanges. It is then connected to a high-temperature heat exchanger on the hydrogen side via a heat exchanger between the hydrogen production fuel side and the hydrotreating feedstock. Waste heat from hydrogen production is used to heat the mixed feedstock before it is passed into the hydrotreating reactor to complete the hydrotreating reaction. This invention uses green hydrogen to replace fossil fuel hydrogen production, achieving clean petroleum product decarbonization throughout its entire life cycle; and improves energy utilization efficiency through heat coupling.
