Characteristic Bio-hydrocarbons and Product Distributions Obtained from Lignin il

(A–D) GC×GC−MS(FID) traces highlighting volatile products obtained from the HDO of poplar (A and C). Distribution of products according their C-atoms (B and D). Reaction conditions: (A and B) high pressure/5 MPa - low temperature/573 K for aliphatics-directed HDO; (C and D): low pressure/0.5 MPa - high temperature/623 K for aromatics-directed HDO. The semi-quantification of the products was performed based on ECN estimation.⁵³
