    • Methods and apparatuses for forming a low-metal biomass-derived pyrolysis oil are provided. In an embodiment, a method for forming a low-metal biomass-derived pyrolysis oil includes washing biomass comprising a water-soluble metal component therein with wash water that is substantially free of water-soluble metals. The washed biomass and water containing water-soluble metal are separated after washing the biomass. The washed biomass is pyrolyzed in a pyrolysis process to form a pyrolysis vapor stream. A portion of the pyrolysis vapor stream is condensed to form a condensate. The wash water is derived from the washed biomass. In an embodiment of an apparatus, the apparatus comprises a washing stage, a biomass dryer, a pyrolysis reactor, a quenching system comprising a primary condenser and a secondary condenser, and a return line that connects the quenching system to the washing stage.
    • 提供了形成低金属生物质衍生的裂解油的方法和装置。 在一个实施方案中,用于形成低金属生物质衍生的热解油的方法包括用基本上不含水溶性金属的洗涤水洗涤其中包含水溶性金属组分的生物质。 在洗涤生物质后,分离经洗涤的生物质和含水溶性金属的水分。 洗涤的生物质在热解过程中热解,形成热解蒸汽流。 一部分热解蒸汽流被冷凝以形成冷凝物。 洗涤水源自洗涤的生物质。 在装置的一个实施方案中,该装置包括洗涤阶段,生物质干燥器,热解反应器,包括初级冷凝器和次级冷凝器的淬火系统,以及将淬火系统连接到洗涤阶段的返回管线。
