Towards sustainable processing of columbite group minerals: Elucidating the relation between dielectric properties and physico-chemical transformations in the mineral phase (2017)
Journal Article

© 2017 The Author(s). Current methodologies for the extraction of tantalum and niobium pose a serious threat to human beings and the environment due to the use of hydrofluoric acid (HF). Niobium and tantalum metal powders and pentoxides are widely us...

Thermal analysis on the pyrolysis of tetrabromobisphenol A (TBBPA) and Electric Arc Furnace Dust mixtures (2017)
Journal Article

The pyrolysis of Tetrabromobisphenol A (TBBPA) mixed with Electric Arc Furnace Dust (EAFD) was studied using thermogravimetric analysis (TGA) and theoretically analysed using thermodynamic equilibrium calculations. Mixtures of both materials with var... Read More about Thermal analysis on the pyrolysis of tetrabromobisphenol A (TBBPA) and Electric Arc Furnace Dust mixtures.

Microwave treatment of electric arc furnace dust with Tetrabromobisphenol A: Dielectric characterization and pyrolysis-leaching (2017)
Journal Article

In the present work microwave treatment of electric arc furnace dust (EAFD) mixed with tetrabromobisphenol A (TBBPA) was investigated. A range of characterization techniques were used to understand the thermal behaviour of TBBPA-EAFD mixtures under m...

Microwave fluidized bed for biomass pyrolysis. Part II: Effect of process parameters (2017)
Journal Article

The microwave fluidized bed process developed in Part I (DOI: 10.1002/bbb.1780), in which the heating heterogeneity issues are overcome, has been applied to the pyrolysis of biomass. The degree of pyrolysis was established by studying the behavior of... Read More about Microwave fluidized bed for biomass pyrolysis. Part II: Effect of process parameters.

Microwave fluidized bed for biomass pyrolysis. Part I: Process design (2017)
Journal Article

The production of bio-oils from microwave pyrolysis has received increasing attention from bioenergy researchers, but no studies reported to date have proposed reliable solutions to avoid thermal runaway. The motivation of this paper is to develop an... Read More about Microwave fluidized bed for biomass pyrolysis. Part I: Process design.

Towards large scale microwave treatment of ores: Part 1 – Basis of design, construction and commissioning (2017)
Journal Article

Despite over thirty years of work, microwave pre-treatment processes for beneficiation of ores have not progressed much further than laboratory testing. In this paper we present a scaleable pilot-scale system for the microwave treatment of ores capab...

Metal-organic frameworks in seconds via selective microwave heating (2017)
Journal Article

© The Royal Society of Chemistry. Synthesis of metal-organic framework (MOF) materials via microwave heating often involves shorter reaction times and offers enhanced control of particle size compared to conventional heating. However, there is little... Read More about Metal-organic frameworks in seconds via selective microwave heating.

Overcoming the caking phenomenon in olive mill wastes (2017)
Journal Article

The use of olive mill wastes (orujillo) within coal fired power stations in the UK has led to unexpected difficulties with material caking within the fuel handling plant. This study replicated orujillo caking on a laboratory scale using a planetary b... Read More about Overcoming the caking phenomenon in olive mill wastes.

New insights into microwave pyrolysis of biomass: preparation of carbon-based products from pecan nutshells and their application in wastewater treatment (2017)
Journal Article

Microwave pyrolysis of pecan nutshell (Carya illinoinensis) biomass was used to produce carbon-based solid products with potential application in contaminated water treatment. A range of analytical techniques were applied to characterize the inter...
