The metal content in the product was &amp;lt;20 ppm after a simple extraction step. A correlation between concentration, temperature, and reaction time with respect to yield of desired product was found. At optimal reaction conditions (treating BL with 16 wt % dry substance at 380 \u00b0C for 20 min), the yield of extractable organics was around 80% of the original lignin with less than 7% of char. The product was analyzed by gel permeable chromatography, mass spectroscopy, nuclear magnetic resonance, elemental analysis, and inductively coupled plasma. It was found that a large fraction composed of mainly cresols, xylenols, and mesitols. This process provides a pathway to convert a major waste stream from a pulp mill into a refinery feed for fuel or chemical production, whereas at the same time the inorganic chemicals are recovered and can be returned back to the pulp mill.<\/jats:p>","DOI":"10.1021\/acsomega.8b00854","type":"journal-article","created":{"date-parts":[[2018,6,21]],"date-time":"2018-06-21T08:37:44Z","timestamp":1529570264000},"page":"6757-6763","source":"Crossref","is-referenced-by-count":31,"title":["High Yields of Bio Oils from Hydrothermal Processing\nof Thin Black Liquor without the Use of Catalysts or Capping Agents"],"prefix":"10.1021","volume":"3","author":[{"given":"Alexander","family":"Orebom","sequence":"first","affiliation":[{"name":"RenFuel AB , Sturegatan 38 , ,","place":["Stockholm, Sweden, 114 36"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
