A sample of kerogen isolated from a Green River oil shale has been examined using high resolution solid state 13 C n.m.r. spectroscopy. The relative concentrations of carbon types have been determined using a novel peak-synthesis technique applied to

The effects on coal hydroliquefaction of organic and pyritic sulphur, and of H 2 S formed from the reductive decomposition of these compounds, are reviewed. Under suitable conditions, all are shown to exert beneficial effects on both product yields a

The pyrolysis of 1-naphthol in nitrogen and hydrogen, with and without a donor solvent, has been studied. The results show that in the absence of a source of donatable hydrogen, phenolic groups can condense at around 450 °C to form fused furan type

The use of flow microcalorimetry to study the kinetics of urea hydrolysis catalyzed by urease bound to porous glass (CPG) particles is described. The present approach involves measurement of the average, rather than initial, rate of reaction. The ext

An enthalpimetric determination of urea using immobilized urease in a flow system is described. Sensitivity of analysis is related to the mole reaction enthalpy (dHR). This is estimated as (61 ±3 kJ mol−1 and 20 ±1 kJ mol−1 in sodium phosphate
