Platform chemicals such as furfural and hydroxymethylfurfural are major products formed during the acid hydrolysis of lignocellulosic biomass in second generation biorefining processes. Solid hydrolysis residues (HR) can amount to 50 wt.% of the starting biomass materials. Pyrolysis of the HRs gives rise to biochar, bio-liquids, and gases. Time and temperature were variables during the pyrolysis of HRs in a fixed bed tubular reactor, and both parameters have major influences on the amounts and properties of the products. Biochar, with potential for carbon sequestration and soil conditioning, composed about half of the HR pyrolysis product. The amounts (11-20 wt.%) and compositions (up to 77% of phenols in organic fraction) of the bio-liquids formed suggest that these have little value as fuels, but could be sources of phenols, and the gas can have application as a fuel.
平台化学品，如糠醛和羟甲基糠醛，是第二代生物炼制过程中木质纤维素生物质酸水解过程中形成的主要产物。固体水解残渣（HR）可达起始生物质材料的 50wt%。HR 在固定床管式反应器中进行热解会产生生物炭、生物液体和气体。在 HR 热解过程中，时间和温度是变量，这两个参数对产物的数量和性质都有重大影响。生物炭具有碳封存和土壤改良的潜力，占 HR 热解产物的一半左右。形成的生物液体的量（11-20wt.%）和组成（有机部分中高达 77%的酚类）表明，这些生物液体作为燃料的价值不大，但可能是酚类的来源，而气体可以作为燃料应用。
