Study on Pyrolysis of Oil Sludge with Microalgae Residue Additive

17-Jan-2018 | Zhiqiang Gong, Zhentong Wang, Zhenbo Wang, Aixun Du, Peiwen Fang, Zhiqian Sun, Xiaoyu Li, The Canadian Journal of Chemical Engineering, 2018

ABSTRACT The pyrolysis of oil sludge (OS) with microalgae residue (MR) additive was conducted with a TGA and a tube furnace. The pyrolysis process of OS with the MR additive can be divided into three stages: 1) water evaporation, 2) the release of light groups of hydrocarbon compounds, the ...


Electrosynthesis of Ferrate in a Batch Reactor at Neutral Conditions for Drinking Water Applications

17-Jan-2018 | Macarena A. Cataldo‐Hernández, Rubenthran Govindarajan, Arman Bonakdarpour, Madjid Mohseni, David P. Wilkinson, The Canadian Journal of Chemical Engineering, 2018

ABSTRACT We report on the electrochemical generation of ferrate species in a batch reactor at neutral conditions (pH ∼7) using boron‐doped diamond (BDD) electrodes and Fe (III) salts for applications in drinking water treatment. The impact of several relevant variables, including current ...


Response Letter to the Editor‐in‐Chief

17-Jan-2018 | Chunshan Li, The Canadian Journal of Chemical Engineering, 2018

Abstract We are sorry for troubling you because of some unclear details in our paper,[1] and deeply appreciate your helpful advice and important comments on our manuscript. According to your recommendations, we have checked our raw data and carefully thought about your comments. We have ...


Performance Evaluation of Fixed‐Bed, Millistructured, and Metallic Foam Reactor Channels for CO2 Methanation

17-Jan-2018 | Alain Bengaouer, Julien Ducamp, Isabelle Champon, Rasmey Try, The Canadian Journal of Chemical Engineering, 2018

ABSTRACT Power‐to‐gas technologies, combining hydrogen produced by water electrolysis with carbon dioxide to produce substitute natural gas (SNG), can support the increased penetration of renewable electricity sources. However, the technical and economic feasibility of these technologies ...


Gaseous Ozone Decomposition over High Silica Zeolitic Frameworks

17-Jan-2018 | Nicolas Brodu, Marie‐Hélène Manero, Caroline Andriantsiferana, Jean‐Stéphane Pic, Héctor Valdés, The Canadian Journal of Chemical Engineering, 2018

Abstract For several decades, it has been known that ozone emissions are harmful to humans, plants, and animals. Heterogeneous catalytic decomposition is an efficient process for removing ozone from air. This study examines the effect of the zeolite's framework and pore width on efficiency ...


Measuring biogas composition with a compact MEMS based spectrometer

17-Jan-2018 | Robin Eccleston, Michael Bongards, Chemical Engineering & Technology, 2018

Abstract In order to operate a demand driven anaerobic digester, improvements to monitoring of process parameters are necessary. Therefore a mid infrared spectroscopic gas sensor utilizing a MEMS (Microelectromechanical systems) based Fabry‐Perot interferometer was tested for its suitability ...


Real time gas quality data for on‐demand production of biogas

17-Jan-2018 | Benedikt Bierer, Hans-Joachim Nägele, Alvaro Ortiz Perez, Jürgen Wöllenstein, Philipp Kress, Andreas Lemmer, Stefan ..., Chemical Engineering & Technology, 2018

Abstract The flexible production of biogas makes it a promising candidate to become the first renewable, on‐demand energy source. But present day approaches for achieving this goal mostly employ cost‐intensive technologies such as gas storage tanks, which are unable to cope with gas surpluses ...


Microbial electrochemical sensors for anaerobic digestion process control –performance of electroactive biofilms under real conditions.

17-Jan-2018 | Jörg Kretzschmar, Paul Böhme, Jan Liebetrau, Michael Mertig, Falk Harnisch, Chemical Engineering & Technology, 2018

Abstract The autonomous growth of Geobacter sp. dominated biofilms on electrodes and their sensitivity on volatile fatty acids (VFA) allows their application as biosensor. Here we report on the implementation of a microbial electrochemical sensor in the anaerobic digestion (AD) process. The ...


Role of Mineral Flotation Technology in Improving Bitumen Extraction from Mined Athabasca Oil Sands: I. Flotation Chemistry of Water‐Based Oil Sand Extraction

16-Jan-2018 | Joe Zhou, Haihong Li, Liyan Zhao, Ross Chow, The Canadian Journal of Chemical Engineering, 2018

ABSTRACT The role of surface hydrophobicity in water‐based oil sand extraction is examined from the perspective of mineral flotation separation. Although anionic carboxylates (sulphonates) released from bitumen are helpful for charging bitumen and liberating bitumen from sand grains, their ...


CFD Simulation of Hydrodynamics Characteristics in a Tank Stirred by a Hollow Self‐Inducing Impeller

13-Jan-2018 | Liangchao Li, Ning Chen, Kefeng Xiang, Beiping Xiang, The Canadian Journal of Chemical Engineering, 2018

ABSTRACT Hollow self‐inducing impellers are often used in gas‐liquid stirred tanks in many industrial processes. To understand the hydrodynamics characteristics of this type of stirred tank under aerated and unaerated conditions, a computational fluid dynamics (CFD) simulation study was ...
