Special Issue Information

Dear Colleagues,

The world is facing major problems related to energy needs, waste generation, and environmental concerns. Process intensification is one of the responses to the major challenge of maintaining the competitiveness of companies in the sector, which are constantly looking for new solutions to meet the ever-increasing demand for products. The intensification of processes has become a topic of growing interest and aims to effectively coordinate the different unit operations and activate synergistic effects during the development of sustainable and efficient chemical and/or biological processes.

This Special Issue on "Process Intensification and Application for Bioprocesses and Green Chemical Engineering" will present new advances in research and development related to process intensification approaches and methods that can significantly reduce equipment size, energy consumption, or waste generation for biomass transformation and valorization processes. Topics include, but are not limited to, the following:

  • Intensified reactor technologies;
  • Intensified separation processes;
  • Catalysis and biocatalysis for efficient catalytic processes;
  • Green solvents for chemistry;
  • Alternative energy sources.

Activated carbon monoliths with developed porosity, high surface area and excellent adsorption properties were successfully prepared from resorcinol-formaldehyde resins using a physical activation method. The primary objective of this study was to examine the impact of key parameters, namely hexamethylenetetramine content (0.08–0.2 g), pyrolysis heating rate (5–20 °C/min) and activation time (1–7 h), on the final characteristics of the activated carbon in order to identify the optimal operating conditions to achieve the desired properties. All the cured resin samples were pyrolyzed at 900 °C under a nitrogen atmosphere, while the activation process took place in the presence of CO2. The evaluation of the activated carbon materials was based on the CO2 adsorption capacity and BET surface area, micropore area and total pore volume, which were employed as the criteria for selecting the optimal activated carbon. The synthesized porous carbon monoliths exhibited good properties: high BET surface area (900 m2/g), high CO2 adsorption capacity (5.33 mmol/g at 0 °C and 1 bar, 3.8 mmol/g at 25 °C and 1 bar) and good CO2 selectivity for CO2/N2 and CO2/CH4 mixtures. These results were obtained with a pyrolysis heating rate of 5 °C/min and a 3 h activation period. Full article
