Asphaltenes obtained from an Arabian Mix vacuum residue were cracked under hydrogen in a batch autoclave at 410–460°C for 5–90 min. The products were fractionated into gas, naphtha, oil, asphaltenes and coke. The feed and several product fractio

In bench-scale autoclaves the hydroliquefaction cross-checking tests of three typical Chinese low rank coals were performed under different conditions. The methods of coal evaluation for hydrogenation reactivity are discussed, focused upon the influe

In order to examine the hydroliquefaction behaviour of Chinese lignites a series of bench scale experiments with four lignites, obtained from Inner Mongolia and province Yunnan, in comparison with three foreign lignites or brown coals were performed

Different oil samples, produced by hydrocracking of vacuum residues, have been characterized by proton NMR spectroscopy. The distribution of various types of carbons and several average structural parameters have been calculated. The analytical data

Solid material is often the main product of chemically reacted coal. In this study, elemental analysis and infrared molecular spectroscopy were therefore used for characterizing the structural changes during reaction. Three seam coals were oxidized i

Bituminous coal, lignite, peat and more recent biogenic materials were reacted as water slurries at 380 °C for short periods with hydrogen, directly and from the water-gas shift reaction, without organic solvents or catalysts. Conversion increases w
