Synthesis of boron-doped carbon nanotubes by thermocatalytic decomposition of ethanol using a floating catalyst chemical vapor deposition method: kinetic study
The effect of different reaction parameters helped in understanding the structure–property relationship in B-doped CNTs. A plausible reaction kinetic model and a reaction mechanism were proposed for the FCCVD synthesis of BCNTs.
Characterization of axial dispersion in a vertical helical coil for gas–liquid–liquid flow at low Reynolds numbers
The RTD of a helical coiled reactor was determined from light absorbance by the tracer step input for various cases of flows. The axial dispersion was quantified in terms of dispersion coefficients using the axial dispersion model.
Production of aromatics from butanol over Ga-promoted HZSM5 catalysts: tuning of benzene–toluene–xylene and ethylbenzene (BTEX) selectivity
The present investigation demonstrates the conversion of n-butanol to aromatics (BTA) including building block aromatics over Ga modified HZSM5 catalysts in a fixed bed reactor under varying process parameters (temperature, pressure, and WHSV).

Sulphur poisoning, water vapour and nitrogen dilution effects on copper-based catalyst dynamics, stability and deactivation during CO2 reduction reactions to methanol
A model of methanol synthesis catalyst deactivation dependent on pressure, temperature and composition was developed to enable flexible process optimization in the era of the variable renewable supplies.
Electrocatalytic hydrogenation of furfural paired with photoelectrochemical oxidation of water and furfural in batch and flow cells
The simultaneous formation of furfuryl alcohol and furoic acid was achieved from electrocatalytic hydrogenation and photoelectrochemical oxidation of furfural, respectively.
Integration of heat recirculating microreactors with thermoelectric modules for power generation: a comparative study using CFD
CFD analysis of the trade-off between the catalytic microreactor and thermoelectric generator can optimize the performance of the integrated device for power generation.
Microkinetic and sensitivity analysis of oxidative dry reforming of methane on Ni–Co catalyst using a reaction mechanism based on Ni
Microkinetic modelling performed for ODRM reaction. Effects of temperature and space–time variations match well with experimental data. Sensitivity analysis was performed to provide a reduced mechanism.
Energy optimization of bio-oil production from biomass by fast pyrolysis using microwaves
Microwave fast pyrolysis leads to higher bio-oil production for flax shives than other biomass. An high heating rate and an optimum energy input are required for maximum bio-oil production. Gas and oil composition is stable with operating conditions.
