Resumen:
The various lignin isolation methods and pretreatments are continuously
developing and thermo-chemical conversion of lignocellulosic biomass and
tuning of the activation parameters are vital to obtaining high energy
density materials. In this review, different lignin extraction methods,
pre-treatments, and influence of the extraction conditions on the yield
and properties are presented. The thermochemical conversion of
lignin-based biomass and application in supercapacitors and hydrogen
storage were investigated. The study revealed that chemical extraction
via the organosolv process pre-sents higher purity and partly preserved
lignin structure compared to sulfur processes. Different pa-rameters
such as the method of extraction, the temperature, pH, resident time,
and pressure greatly influences the Kappa value and yield of lignin. The
potassium hydroxide (KOH) dosage as an activating agent and the
activating temperature is vital to obtaining high surface area and
microporosity, which enhances the lignin-based activated carbon
performance towards high hydrogen storage and capaci-tance. Metals
doping on activated carbon marginally enhance the hydrogen storage
capacity and capacitance, however, reversible desorption of the adsorbed
hydrogen requires a higher temperature for hydrogen storage. Besides,
high metal doping reduces available surface area, collapses the
cage-like structures of fullerenes, and results in lower hydrogen
storage capacity of activated carbon. The pres-ence of heteroatoms on
activated carbons enhances the performance towards high hydrogen storage
and capacitance. Moreover, techno-economic and exergy-based
sustainability analysis of the different lignin isolation techniques
must be explored to provide valuable insights on energy and associated
operational costs.
