A Novel Clean Energy-Based Technique in Processing Pulp and Paper, Patented by Dr. Sherif Farag and Professor Jamal Chaouki

It is time to start embedding clean electricity with unconventional heating techniques into pulp and paper manufacturing processes. Recently, PEARL members, Dr. Sherif Farag and Prof. Jamal Chaouki, have invented a process to recover the inorganic chemicals of the pulp and paper making processes using microwaves. The invented  process avoids the pollutants formed from the recovery processes rely on the burning of black liquor; saves the chemicals consumed in the techniques rely on the precipitation of lignin; does not limit the growth in the pulp and paper production; decreases the massive budget needed for the centralized conversion methods; does not squander the value of the chemical products that can be produced from black liquor, among other unique advantages.

This patent has been registered in USPTO under patent number US20190119852. We invite you to read more about this patent here.

PEARL featured in Plan Magazine

The Plan Magazine, the engineering journal of Quebec, in their last issue September-October 2018 has been dedicated to Pyrowave company, which was received the 2018 Genius Innovation Award from the Ordre des ingénieurs du Québec (OIQ). This company was co-founded by Jamal Chaouki, Jucelyn Ducet, and Jean-Philippe Laviolette, head and alumni of PEARL.

Pyrowave was awarded the OIQ’s 2018 Genius Innovation Award for its cost effective waste-to-feedstock technology which depolymerize the household plastic waste into its constituent monomers which then can be re-used for another cycle of polymerization. Chaouki, Doucet and Laviolette accepted this award during the 2018 Excellence in Engineering Evening of the Ordre des ingénieurs du Québec, held on May 30, 2018 in Montreal.

From Complex Feedstocks to New Processes: The Role of the Newly Developed Micro-Reactors

Pilot plant reactors offer very important advantages in testing operating conditions such as temperature, pressure, residence time, catalyst to feed ratio, instrumentation and so on. However, such units are very costly when used, for example, for catalyst and feedstock screening tests where many tests are required to find out the effect of new formulations on product yield under different operating conditions. Micro-reactors are, on the other hand, ideal equipment for such purposes as with such systems running an operation is not expensive, performing a test does not take significant time, switching from an operating condition to one another is rather quick and above all, mass of required catalyst and feedstock is small i.e. in the order of grams. Therefore, considerable time and cost are saved through running tests in the small-scale reactors.

PEARL members Dr. Said Samih, Dr. Mohammad Latifi, Dr. Sherif Farag and Prof. Jamal Chaouki reviewed some state-of-the-art micro-reactors that they have developed and commissioned at PEARL in the Journal of Chemical Engineering and Processing- Process Intensification.  

New Approach for Analyzing Rare Earth Elements (REE) Developed by PEARL members

Dr. Cornelia Chilan from the Physics-Engineering Department and Pearl members Maryam Abdollahi Neisiani, Dr. Mohammad Latifi, Prof. Jamal Chaouki developed a new approach for analyzing rare earth elements (REE) in high content mineral matrices by Neutron Activation Analysis (NAA). 

REE k0 and Q0 values, spectral interferences and nuclear interferences were experimentally evaluated and improved with Alfa Aesar Specpure Plasma Standard 1000 mg kg-1 mono-rare earth solutions. The new iterative gamma-ray self-attenuation and neutron self-shielding methods were investigated with powder standards prepared from 100 mg of 99.9% Alfa Aesar mono rare earth oxide diluted with silica oxide. The overall performance of the new k0-NAA method for REEs was validated using a certified reference material (CRM) from Canadian Certified Reference Materials Project (REE-2). The REE concentration was determined with an uncertainty below 7% (at 95% confidence level) and proved good consistency with the CRM certified concentrations.

Fluidization XVI Conference : May 26-31, 2019

The next Fluidization Conference, Fluidization XVI, will be held in China on May 26-31 2019. This conference aims to gather students, professors, and world-renowned experts in the field from both academia and industry. Following the successful 2016 conference, the top selected abstracts will be invited to submit a full paper in Powder Technology Journal as a special issue of this conference, which is expected to be published by the end of 2019.

In this conference, Professor Jamal Chaouki, the head of PEARL, has been invited to give a plenary speech. In his talk, he will be presenting the most recent research findings in the filed from PEARL.

Students and researchers can submit their abstracts until October 31, 2018, in different areas such as fundamentals of fluidization, modeling and simulation, fluidized bed applications, and fluidization in nature.

A Novel Technique to Measure Kinetic Parameters of Pyrolysis and Gasification Reactions

Said Samih and Jamal Chaouki have recently published a research article in the Canadian Journal of Chemical Engineering. The developed Fluidized Bed Thermogravimetric Analyzer (FB-TGA) in PEARL group was employed to investigate the pyrolysis and gasification of coal. Syngas (a mixture of CO and H2) was produced from such a complex feedstock, and novel kinetic parameters were predicted. Five grams of coal was gasified without observing a diffusion control step. In contrary to the conventional TGAs, the thermocouple of the FB-TGA measured the direct temperature of the reaction in this work, and consequently, the temperature gradient was eliminated. This unique technique allows the development of novel kinetic parameters from the FB-TGA for both pyrolysis and gasification reactions.
