This study systematically investigated six catalysts (K2CO3, Na2CO3, KHCO3, NaHCO3, KOH, NaOH) for product distribution and nitrogen migration in STL versus hydrothermal liquefaction (HTL). Results demonstrate K2CO3's superiority in ethanol-water co-solvent, synergistically enhancing bio-oil yield to 57.18 % (calorific value 35.49 MJ/kg) while achieving directional denitrification - reducing nitrogen content to 22.99 wt.% via pH-driven protein deamidation. Sulfur content decreased to 0.13 wt.% through sulfide decomposition. Critically, this method optimized bio-oil composition: light fractions (<343 °C) reached 82.10 % and hydrocarbons increased to 14.47 %, significantly outperforming HTL. Moreover, ethanol solvent recycling maintained 35.16 % bio-oil yield after three reuse cycles (distillation and antioxidants required), exceeding conventional HTL conversion (67.72 %). This work establishes three advances: (1) K2CO3-ethanol synergy enables high-yield, low-nitrogen bio-oil; (2) Alkaline catalysis directionally removes N/S impurities; (3) Multi-cycle solvent reuse sustains efficient oil production, providing a sustainable pathway for wet waste valorization.","PeriodicalId":258,"journal":{"name":"Bioresource Technology","volume":" ","pages":"133111"},"PeriodicalIF":9.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144797687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigated the effect of magnetic field (MF)-coupled magnetic carbon dots (N-CD/Fe3O4) as a selective pressure on the structure of mixed microbial communities in an intermittent pulsating fluidized-bed bioelectrochemical reactor. Under a moderate magnetic field (15 mT), N-CD/Fe3O4 were effectively adsorbed onto microbial cells and subsequently aggregated, significantly enhancing electron transfer within the community. The maximum power density reached 38.43 mW/m2, which is about 5.07 times that of the blank control group. 16S rRNA and metagenomic analyses showed that the MF (15 mT) group exhibited significant enrichment of typical electroactive bacteria (40.32 %), such as Geobacter, which directly contributed to improved power production performance. In contrast, under a stronger magnetic field (60 mT), the abundance of typical electroactive bacteria (17.94 %) decreased, while atypical electroactive (38 %) and metabolically complementary bacteria that facilitate syntrophic cooperation (42.85 %) showed adjusted abundances, forming a functionally more balanced microbial community with improved adaptability to real wastewater conditions.

Four operating modes were investigated: constant power with/without high-temperature alarm, fixed temperature, and controlled heating-rate; and two novel metrics (carbonized amount and absolute yield) were studied alongside traditional metrics to more accurately quantify biochar production and quality. Microwave power and residence time emerged as the primary drivers of yield and carbonization, while heating rate and target temperature acted as fundamental dependent factors. Constant-power operation without alarm achieved the highest reproducibility and absolute yield (up to 33.85 %), whereas controlled ramping produced biochars with HHV > 30 MJ/kg and fixed carbon > 70 %.
