Biochar slurry as well as preparation method and application thereof

The invention relates to the technical field of clean energy utilization, in particular to charcoal slurry as well as a preparation method and application thereof. The preparation method provided by the invention comprises the following steps: under a stirring condition, gradually adding pyrolytic carbon powder into wood vinegar to obtain biochar slurry; the dosage ratio of the wood vinegar to the pyrolytic carbon powder is 100 mL: (62.09 to 74.43) g. According to the preparation method, the pulping property of the biochar is improved, the agglomeration phenomenon is avoided, and the problem that gas-carbon co-production solid-liquid products are difficult to efficiently and intensively utilize is solved. 本发明涉及清洁能源利用技术领域，尤其涉及一种生物炭料浆及其制备方法和应用。本发明提供的制备方法，包括以下步骤：在搅拌的条件下，在木醋液中逐次加入热解炭粉末，得到所述生物炭料浆；所述木醋液和热解炭粉的用量比为100mL：(62.09～74.43)g。所述制备方法改善了生物炭的成浆性，避免团聚现象出现，解决了气炭联产固液产物难以高效集中利用的问题。
