Bio-oils were produced through intermediate (IP) and fast pyrolysis (FP), using Eucalyptus sp. (hardwood) and Picea abies (softwood), wood wastes produced in large scale in Pulp and Paper industries. Characterization of these bio-oils was made using GC/qMS and GC×GC/TOFMS. The use of GC×GC provided a broader characterization of bio-oils and it allowed tracing potential markers of hardwood bio-oil, such as dimethoxy-phenols, which might co-elute in 1D-GC. Catalytic FP increased the percentage of aromatic hydrocarbons in P. abies bio-oil, indicating its potential for fuel production. However, the presence of polyaromatic hydrocarbons (PAH) draws attention to the need of a proper management of pyrolysis process in order to avoid the production of toxic compounds and also to the importance of GC×GC/TOFMS use to avoid co-elutions and consequent inaccuracies related to identification and quantification associated with GC/qMS. Ketones and phenols were the major bio-oil compounds and they might be applied to polymer production.
生物油通过中间（IP）和快速热解（FP）产生，使用桉树（硬木）和云杉（软木），这两种木材是纸浆和造纸工业大规模产生的废料。使用 GC/qMS 和 GC×GC/TOFMS 对这些生物油进行了表征。GC×GC 的使用提供了对生物油的更广泛的表征，并且它允许追踪硬木生物油的潜在标志物，例如二甲氧基苯酚，其可能在一维 GC 中共同洗脱。催化 FP 增加了云杉生物油中芳烃的百分比，表明其具有燃料生产的潜力。然而，多环芳烃（PAH）的存在引起了人们对适当管理热解过程以避免产生有毒化合物的关注，并且还引起了对使用 GC×GC/TOFMS 的重视，以避免共洗脱和与 GC/qMS 相关的鉴定和定量相关的不准确性。酮和酚是主要的生物油化合物，它们可用于聚合物生产。
