Dr. Mohammad Latifi has been working as a postdoc and then a research associate and project manager at professor Jamal Chaouki’s group. In addition to the research, he has been teaching the graduate course of “design of gas-solid reactors/fluidized bed reactors”, and he has been advising graduate students.

His primary research interests lay in process engineering, particularly, in reaction engineering, powders technology and material engineering. He has been the lead researcher in a wide range of industrial projects such as upgrading the conventional and renewable energy resources (thermal and catalytic cracking, steam/dry reforming, co-combustion, gasification and pyrolysis), carbon capture, mineral processing and coating of the nano powders. Such projects were related to major industries such as oil, gas and petrochemicals, power plants, biorefinery/bioenergy, waste/residue valorization, syngas, mining and metallurgy, and rechargeable lithium ion batteries.

Having worked in Industry and academia, he gained tremendous theoretical and practical experience in bench-scale and pilot-scale process development, design of fluidized bed reactors, hydrodynamic studies, kinetics, catalysis, materials characterization and analytical methods on gas, liquid and solids.

Dr. Mohammad Latifi is the designer of two novel fluidized bed micro reactors: Jiggle Bed Reactor (JBR) and Induction Heating Fluidized Bed Reactor (IHFBR).



I’ve been introduced to fluidization research as an undergrad research assistant since 1995. Under the wing of Rahmat Sotudeh, then PhD student in Prof Chaouki’s group, I learned and worked on many aspects of high temperature fluidized bed: hydrodynamics, simple modeling and experimental methods. This led to a year-long internship in Dupont Experimental Station as part of the team that supported a maleic anhydride production CFB reactor, where I was introduced to many aspects of industrial research.

My PhD mostly focussed on the measurement and characterization of the gas jets (penetration lengths) in fluidized beds using fibre optic probe, but I also made it a priority to learn about the group’s measurement techniques suitable for gas-solid systems (e.g. RPT, radiotracers). This work led to correlations for the prediction of the characteristic jet lengths (Lmin, Lmax and Lb) for upward and downward gas jets in gas-solid fluidized bed.

I worked at UBC (project with Ballard Power Systems) on water management of PEM fuel cells, developing and using a sensitive water balance apparatus to determine the net diffusion of water on laboratory sized mimicking cells the local distribution of larger cells.

I worked with FPInnovations as part of a team promoting a stepwise approach for the introduction of gasifiers in the pulp and paper industry towards a biorefinery. The work involved making calculations to show member companies the impact of fossil fuel displacement by syngas in lime kilns; preparing literature reviews of syngas cleanup and conditioning, and synthesis pathways to value added chemicals.

As post doc, I worked closely with A. Rakid and J. Shabanian on the co-combustion of ReEF™ and coal in a BFB to displace CO2 emissions while mitigating criteria air contaminant emissions. The work led to a sorbent composition mapping to predict conditions susceptible to defluidization.

I currently work as project manager on the piloting of a melt synthesis approach to prepare LiFePO4/C for Li-based batteries. The project involves around 30 individuals (students, PDFs, RAs, professors, and scientists) from 5 organizations (Polytechnique de Montréal, Université de Montréal, Western University, CanmetMATERIALS, and Johnson Matthey) and is supported as part of the Automotive Partnership Canada program. The main objective is reducing the cost of LiFePO4/C to make it a viable option as a cathode material for vehicular applications.
