The paper presents experimental data of catalytic steam gasification of brown coal containing aqua-iron species, and the chemical mechanism(s) at a molecular level. Experimental techniques provided weight loss from catalysed reaction of char with ste

The electrochemical and photophysical properties of biscyclometallated iridium(III) complexes containing phenanthroline-based ligands have been investigated and compared in organic and aqueous media. Complexes having general formula [Ir(ppy)2(N∩N)]

Low-rank coals can be processed into non-fouling coal, ultra-low ash coal, and coals containing catalysts. Systematic studies of the action of acid to reduce ash in a number of low-rank coals have shown total ash reduction varied from 96% to 30%; the

The crystal structures of tetrachloroferrate(III) complexes having stoichiometry (BH)+ [FeCl4]− (where B = isoquinoline and 4-aminopyridine) were determined at 100 K. While weak interactions, particularly N–H···Cl hydrogen bonds, are evident i

Surface effects on Mong Hsu rubies and Kanchanaburi sapphires after heat treatment in a controlled reducing atmosphere (5 mol% H 2 /Ar) have been investigated using advanced surface science techniques including X-ray photoelectron spectroscopy (XPS)

Low-rank coal is a complex mixture; consequently, it is necessary to develop simpler molecular representations for computational modeling. Our modeling objective has been to develop molecules suitable for semi-empirical (SE) computations of low-rank

Pyrolysis and catalytic steam gasification of brown coal containing iron hydroxyl complexes have been investigated experimentally and with semi-empirical and density functional theory molecular modelling. Pyrolysis yielded mainly CO 2 , CO, and reduc

The neutral mer-triaquatrichloroiron(III) molecule, mer-[(H2O)3FeCl3], has been structurally defined, co-crystallized with a pair of organic-cation/chloride salts, from hydrochloric acid solution in each case. The array {[HN(CH2CH2)3NH]Cl2}{mer-[(H2O

Reduction in ash constituents by water washing, and also at specific pH values, was systematically studied for three low-rank coals. Acid treatment removed inorganic constituents if accompanied by efficient water washing; at elevated temperatures thi

This paper is an overview of the calculations performed on various molecular models of char containing iron species, developed from a brown coal model with iron complexes, to mimic pyrolysis over 200−700 °C. The semiempirical (SE) optimization of
