摘要本研究旨在通过表征和比较快速热解产物的产率，比较维吉尼亚锦葵与其他高产多年生草本和硬木的潜力。本研究选择的原料包括芒草（miscanthus x giganteus）、弗吉尼亚锦葵（Sida hermaphrodita）、短旋柳树（SRC） （Salix viminalis）和橡树（Quercus robur）。实验工作分为两个部分：分析（Py-GC-MS）和使用300 g h−1连续鼓泡流化床反应器的实验室规模处理。热解-气相色谱-质谱（Py-GC-MS）通过模拟快速热解加热速率，使用CDS 5200热解器与PerkinElmer Clarus 680气相色谱-质谱联用来定量这些原料的热解产物。弗吉尼亚锦葵、柳树和橡树的生物油产量较高（分别为65.36%、62.55%和66.43%），但由于原料灰分含量增加，芒草的产量仅为53.46%。芒草中生物油的含水量最高（17.64 wt%），而维吉尼亚锦葵、硬木柳树和橡木的含水量相对较低（12.49、13.88和14.53 wt%）。与柳树SRC相比，弗吉尼亚锦葵具有类似的高产量生物油和低产量的木炭和不可冷凝气体，这使得弗吉尼亚锦葵成为快速热解处理的有吸引力的原料。图形抽象
AbstractThis study aims to compare the potential of Virginia mallow to other high yielding perennial grasses and hardwoods by characterising and comparing fast pyrolysis product yields. Feedstocks selected for this study include miscanthus (Miscanthus x giganteus), Virginia mallow (Sida hermaphrodita), willow short rotation coppice (SRC) (Salix viminalis) and oak (Quercus robur). The experimental work was split into two sections: analytical (Py–GC–MS) and laboratory-scale processing using a 300 g h−1continuous bubbling fluidised bed reactor. Pyrolysis–gas chromatography–mass spectrometry (Py–GC–MS) has been used to quantify pyrolysis products from these feedstocks by simulating fast pyrolysis heating rates using a CDS 5200 pyrolyser closed coupled to a PerkinElmer Clarus 680 GC–MS. High bio-oil yields were achieved for Virginia mallow, willow SRC and oak (65.36, 62.55 and 66.43 wt% respectively), but miscanthus only produced a yield of 53.46 wt% due to increased feedstock ash content. The water content in the bio-oil is highest from miscanthus (17.64 wt%) and relatively low in the Virginia mallow and hardwoods willow SRC and oak (12.49, 13.88 and 14.53 wt%). Similar high yields of bio-oil and low yields of char and non-condensable gas compared to willow SRC make Virginia mallow an attractive feedstock for fast pyrolysis processing.Graphic Abstract
