Detailed gasification process of woody biomass-derived char with H2O and CO2 gasifying agents

Journal of Thermal Science and Technology, 2020
To effectively utilize renewable biomass resources, gasification technology is being actively developed. Many studies have been performed regarding the gasification of biomass-derived char (i.e., biochar), where the gasification rate varies greatly with ...

Operational Performance Implications of Circular Economy Implementation: An Empirical Exploration in the Manufacturing Sector

Business Strategy and the Environment, EarlyView.
ABSTRACT The global manufacturing sector has increasingly adopted circular economy (CE) practices to address sustainability challenges and improve operational efficiency. This study explores the impact of five CE practices—reduce, reuse, remanufacture, recycle, and recover—on key operational performance dimensions: quality, speed, dependability ...

A study of Ni‐Co/CeO2 catalyst derived from metal–organic framework for dry reforming of methane

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The efficacy of cobalt‐doped, MOF‐derived catalysts for dry reforming of methane (DRM) was examined. The focus was on the influence of varying nickel and cobalt molar ratios on catalytic performance. Three catalysts with Ni:Co ratios of 1:1, 1:0.5, and 0.5:1, were synthesized and tested with cerium oxide as a constant support. The DRM reaction

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 ...

A‐optimal model‐based design of experiments for processes with uncertain inputs

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Model‐based design of experiments (MBDoE) techniques are tools for selecting experimental conditions that enable accurate parameter estimation for mechanistic models. Most MBDoE approaches assume that the selected experimental conditions will be implemented perfectly, without uncertainties in the independent variables.

In‐situ asphaltene capture with iron oxide nanoparticles in steam‐assisted gravity drainage (SAGD) for improved recovery and partial upgrading of bitumen

The Canadian Journal of Chemical Engineering, EarlyView.
Key improvements obtained by incorporating nanoparticles into a lab‐scale SAGD process configuration. The bar plots show enhanced oil recovery, reduced viscosity, and increased asphaltene adsorption in nanoparticle‐assisted scenarios compared with conventional SAGD.

Investigation of non-isothermal and isothermal gasification process of coal char using different kinetic model

International Journal of Mining Science and Technology, 2015
Isothermal and non-isothermal gasification kinetics of coal char were investigated by using thermogravimetric analysis (TGA) in CO2 atmosphere, and the experimental data were interpreted with the aids of random pore model (RPM), unreacted shrinking core ...
