Preparation of Palm Oil Industry’s Biomass-Based Graphene Composite for the Adsorptive Removal of Methylene Blue

open access: yesAdsorption Science & Technology, 2021
The ability of POME-based graphene shell composite (P-GSC), an adsorbent generated from oil palm wastes abundantly available in Malaysia such as POME and PKS, was examined in removing methylene blue (MB) dye by adsorption.

Adsorption of γ-Valerolactone: An Alternative for Solvent Recovery after Conversion of Lignocellulosic Biomass to Fermentable Sugars [PDF]

open access: yesChemical and Biochemical Engineering Quarterly, 2022
The γ-valerolactone is an effective solvent in solubilizing lignocellulosic biomass fractions, although it inhibits microbial activity. To avoid the negative effects on the metabolism of microorganisms, even small quantities of γ-valerolactone need to be

Dynamic models for start-up operations of batch distillation columns with experimental validation [PDF]

open access: yes, 2004
The simulation of batch distillation columns during start-up operations is a very challenging modelling problem because of the complex dynamic behaviour. Only few rigorous models for distillation columns start-up are available in literature and generally
