Enhancing energy recovery from waste through torrefaction: A study on municipal solid waste (MSW) fractions under N2 and CO2 atmospheres

The Canadian Journal of Chemical Engineering, EarlyView.
An overview of municipal solid waste torrefaction under various sweep gases. Abstract This study investigates the impact of torrefaction on municipal solid waste (MSW) fractions, focusing on energy recovery, calorific value enhancement, mass yield reduction, and energy densification under both nitrogen (N2) and carbon dioxide (CO2) atmospheres.

Sensitivity analysis and stochastic optimization of levelized cost of hydrogen production through methane pyrolysis

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Hydrogen plays a crucial role across multiple industrial sectors and is increasingly recognized as a clean energy carrier with significant potential in decarbonization efforts. Methane pyrolysis (MP), particularly using molten metal catalysts, offers a promising pathway for hydrogen production with low CO2 emissions.

Production of middle distillates through olefin oligomerization using ZSM‐5 as a catalyst

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The global transportation sector relies heavily on gasoline (C5–C12) and diesel (C11–C24), which together account for approximately 60% of its energy needs. Driven by rapid industrialization and urbanization, diesel consumption is outpacing gasoline, with projections estimating global demand by 2035 at 27 million barrels per day for gasoline ...
