Pyrolysis oil, sometimes also known as bio-crude or bio-oil, is a synthetic fuel under investigation as substitute for petroleum. It is obtained by heating dried biomass without oxygen in a reactor at a temperature of about 500 °C (900 °F) with subsequent cooling. Pyrolysis oil is a kind of tar and normally contains levels of oxygen too high to be considered a pure hydrocarbon. This high oxygen content results in non-volatility, corrosiveness, immiscibility with fossil fuels, thermal instability, and a tendency to polymerize when exposed to air. As such, it is distinctly different from petroleum products. Removing oxygen from bio-oil or nitrogen from algal bio-oil is known as upgrading.

  • Pyrolyseöl (auch „Bio-Öl“ oder „Biocrudeoil“ genannt) ist eine dunkelbraune Flüssigkeit, die durch Pyrolyse von organischen Stoffen, etwa von Biomasse oder Kunststoffabfällen bei Temperaturen von zirka 500 °C gewonnen wird. Obgleich pflanzlicher Herkunft, besteht Pyrolyseöl im Gegensatz zu den weitgehend aus Fettsäuren zusammengesetzten Pflanzenölen aus einer Vielzahl chemischer Verbindungen. Neben der Verwendung als Biokraftstoff, Heizkomponente oder energiereiches Zwischenprodukt kann Pyrolyseöl als Rohstoffquelle für chemische Anwendungen zum Einsatz kommen. (de)
  • L'huile pyrolytique est un carburant de synthèse pour lequel des recherches sont en cours pour en faire un substitut du pétrole. Au moyen d'une technologie de distillation destructive du type biomass to liquid, on l'extrait de la biomasse séchée dans un réacteur à la température d'environ 500 °C avec un refroidissement ultérieur. L'huile pyrolytique est une sorte de goudron, et normalement sa teneur en oxygène est trop élevée pour en faire un hydrocarbure. À ce titre, elle diffère nettement des produits pétroliers similaires.

  • Bio-óleo é um líquido negro obtido por meio do processo de pirólise, no qual a biomassa é submetida a altas temperaturas em um ambiente isolado com pouco ou nenhum oxigênio. É utilizado principalmente como combustível para aquecimento e a geração de energia elétrica. (pt)
  • Olej popirolityczny (od gr. piroliza 'rozkład pod wpływem ognia') – półprodukt chemiczny pochodzący z produkcji olefin (krakowanie parowe). Olej popirolityczny jest produktem niestandaryzowanym, ubocznym. Producent deklaruje jego lepkość i gęstość jako wartości zmienne w dużym przedziale, niestabilne. Wartość opałowa i zawartość siarki nie są przez producenta normowane, bowiem olej popirolityczny nie jest olejem opałowym, a jedynie półproduktem do jego komponowania. Stosowany jest również jako produkt handlowy np. do produkcji sadzy i żywic. (pl)
