Pearl Members Takes Third Place in Aero Montréal Recycling Competition

Mohamed Khalil, Soumaya Benzennou (doctoral students) and Majid Rasouli (Postdoctoral) representing PEARL received the third prize at final round of Aéro Montréal Competition, granted by Bombardier Inc. and Avianor Inc., that was held on October 1st.
The competition, Aerospace of Tomorrow: Towards a 100% Recyclable Aircraft, was to encourage young engineers to propose a solution for recycling 100% of an end-of-life aircraft.
PEARL’s proposal suggested a solution for recycling the end-of-life composite materials and electronics waste using the Microwave Assisted Pyrolysis technology, which could greatly facilitate moving forward to produce clean and high quality products including precious metals like gold, silver and platinum from aerospace scrap.

A Better Understanding of the Technologies for Greenhouse Gases Reduction and Their Challenges, by Jamal Chaouki

Jamal-Chaouki-29-06-19The principal anthropogenic source of greenhouse gas emissions (GHG) is the energy production from fossil fuels. According to the Intergovernmental Panel on Climate Change(IPCC) 2: 78% of human emissions of greenhouse gases come from burning fossil fuels such as coal, natural gas and oil. Other sources include cement production (7%), refineries (6%), iron and steel industries (5%) and petrochemical industries (3%).

A Unique Research Publication on the Influence of Interparticle Force on Solids Motion in a Bubbling Gas-Solid Fluidized Bed

jaberIt is our pleasure to announce the recent publication by Jaber Shabanian and Jamal Chaouki  in Powder Technology. An in-depth study was carried out with the help of the radioactive particle tracking technique while adopting a polymer coating approach to increase the level of IPFs in a bed of fresh sugar beads. This helped highlighting the effect of IPFs on solids motion in a bubbling gas-solid fluidized bed. Experimental results showed that the quality of solids mixing decreased with the level of cohesive IPFs in the bed. In addition, by calculating the idle time for systems with varying degrees of IPFs and resembling the agglomeration process to a reaction network, i.e., the idle time represents the effective reaction time and all reactions follow the elementary rate law, we could provide a fundamental understanding about why the agglomeration process, which normally occurs for beds approaching complete defluidization at elevated temperature, is an auto-accelerated phenomenon.
