The investigation of the reaction's kinetics is one of the most crucial aspects of the design of a commercial process. The current research investigates the kinetics of Fischer–Tropsch synthesis using a perovskite catalyst. The LaFe0.7 Co0.3 O3 perovskite catalyst was prepared via the thermal sol–gel technique and characterized using BET, XRD, SEM, and H2-TPR techniques. According to operating conditions (e.g. H2/CO: 1–2, pressure: 10–20 barg, temperature: 240–300 °C, and GHSV: 3000 1/h), Fischer–Tropsch reaction kinetics (CO conversion) were carried out in a fixed-bed reactor. Using the framework of Langmuir–Hinshelwood–Hougen–Watson (LHHW) theories, 18 kinetic expressions for CO conversion were derived, and all were fitted to experimental data one by one to determine the optimum condition. The correlation was derived from experimental data and well-fitted using LHHW form (according to the enol mechanism, carbon monoxide and dissociated hydrogen atoms are adsorbed and reacted on the surface of the catalyst) −rCO = kpbCOPCO(bH2PH2)0.5/(1 + bCOPCO + (bH2PH2)0.5)2. Finally, the activation energy of the optimum kinetic model was determined with respect to the Arrhenius equation under various operating conditions. The activation energy of perovskite catalyst is about 106.25 kJ/mol at temperatures 240–300 °C, pressures 10–20 barg, and H2/CO ratios 1–2, which is lower than other types of catalyst. Therefore, the catalyst was activated at a high temperature and demonstrated stable performance without any temperature runaway and coking issues.

“…Song et al [ 6 ] present a review of the pre‐treatment, processing, extraction, and purification techniques for obtaining cannabis concentrates and extracts. Yahyazadeh et al [ 7 ] evaluate the CO activation mechanism and consumption rate during the Fischer–Tropsch reaction through detailed experimentation with KMo bimetallic‐promoted Fe catalyst supported on carbon nanotubes. Pal and Agarwal [ 8 ] investigate the use of a novel mixed‐matrix‐membrane, incorporating a polysaccharide‐based natural polymer, functionalized carbon nanotube, and graphene oxide for gas separation applications.…”

We are pleased to present this special issue section of The Canadian Journal of Chemical Engineering (CJCE) to commemorate the India-Canada Joint International Symposium, included in the 74th Annual Session of the Indian Institute of Chemical Engineers (IIChE), held in Bhubaneswar, Odisha, India, during 27-30 December 2021. Like other similar joint symposia held in the past, the Canadian Society for Chemical Engineering (CSChE) and the IIChE co-sponsored this joint symposium.The Indian Chemical Engineering Congress conferences (CHEMCONs) are flagship annual events of the IIChE, which attract national and international experts in chemical engineering and allied fields. CHEMCON-2021 featured many other events, including memorial lectures, plenary lectures, international symposia, panel discussions, and so on. CHEMCON-2021 was planned to be an in-person conference; however, it was converted into a mostly remote event because of the travel and meeting restrictions due to the coronavirus pandemic. The planning for the joint symposium, on Sustainable Energy and the Environment, occurred in several monthly meetings of the guest co-editors of this special issue section. The joint symposium session, held remotely on
