This study highlights the effectiveness of hydrodeoxygenation (HDO) in converting lignin oils from Eucalyptus, Poplar, and Pine wood, derived from reductive catalytic fractionation (RCF), into renewable cycloalkanes for jet fuel. Using a low-cost Ni2P/SiO2 catalyst, the process achieved yields of 91 %, 83 %, and 75 % of renewable cycloalkanes respectively. In addition, the process exhibited high selectivity towards a specific range of hydrocarbons mostly present in aviation fuel (C9 to C15), with values of 70%, 60% and 62% for the three feedstocks, respectively, showcasing the potential for high-value fuel production. The research underscores the importance of modifying lignin oil properties through various chemo-catalytic biorefining pathways, which significantly influence the quality of the produced blend via HDO. These findings provide valuable insights into optimizing feedstock characteristics for improved jet-range hydrocarbon production.

Catalytic refining of lignin holds promise for producing sustainable platform chemicals. In this work, a gaseous hydrogen-free catalytic hydrodeoxygenation system is developed for upgrading lignin-derived phenols to alkane chemicals. Commercially available Raney Ni and HZSM-5 are used as a combinational catalyst, with isopropanol serving as the hydrogen-donating solvent.

With the rising demand for fuel and the societal shift toward sustainable resources, lignin emerges as a prime feedstock. Lignin is mainly composed of aromatic compounds linked within a complex matrix and holds significant potential as a source of renewable aromatics. Technical lignin, the most abundant form of lignin, is often degraded due to harsh biomass pretreatment processes.

Sugarcane, which provides 80% of global table sugar and 40% of biofuel, presents unique breeding challenges due to its highly polyploid, heterozygous, and frequently aneuploid genome. Significant progress has been made in developing genetic resources, including the recently completed reference genome of the sugarcane cultivar R570 and pan-genomic resources from sorghum, a closely related diploid species. Biotechnological approaches including RNA interference (RNAi), overexpression of transgenes, and gene editing technologies offer promising avenues for accelerating sugarcane improvement.
