测试了Fraunhofer UMSICHT获得专利的热催化重整（TCR®）装置，以将木质纤维素生物质和三种有机废物（废纸浆、造纸污泥和污水污泥）转化为增强的热解产物。TCR®反应器是连接到重整器的中间热解螺杆反应器。hawse已经在2 kg h−1实验室规模的工厂中探索了四种原料的TCR®。这项工作的目的是比较在相同的热解条件下（400 °C热解和700 °C后催化重整）使用TCR®获得的产品产率和质量（生物炭、生物油和合成气）。最后，在几个温度下蒸馏造纸污泥生物油以获得油馏分。以四种不同的生物质为原料，分别得到了高质量的生物油和合成气，并与传统的中间热解和快速热解进行了比较。生物油显示出与所使用的生物质的种类无关的较高的热值（HHV）（35-38 MJ kg−1），并且总酸值为1.8-5.4 mgKOH g−1。分馏导致类似汽油的轻馏分和74%的总蒸馏率。
A thermocatalytic reforming (TCR®) unit patented by Fraunhofer UMSICHT was tested to convert lignocellulosic biomass and three organic wastes, digestate, paper sludge, and sewage sludge, into enhanced pyrolysis products. The TCR® reactor is an intermediate pyrolysis screw reactor connected to a reformer. hawse have explored the TCR® of four feedstocks in a 2 kg h−1 laboratory-scale plant. The aim of the work was to compare the product yields and qualities (biochar, bio-oil, and syngas) obtained by using TCR® under the same pyrolysis conditions (pyrolysis at 400 °C and postcatalytic reforming at 700 °C). Finally, paper sludge bio-oil was distilled at several temperatures to obtain the oil fractions. High-quality bio-oil and syngas from four different kinds of biomass were obtained and compared to that from traditional intermediate pyrolysis and fast pyrolysis. The bio-oil showed a high higher heating value (HHV) (35–38 MJ kg−1) independent of the kind of biomass used, and the total acid number was 1.8–5.4 mgKOH g−1. Fractional distillation led to a gasoline-like light fraction and an overall distillation rate of 74 %.
