NO x and particulate matter are the main environmental hazards in the diesel exhaust. In order to explore a suitable method to remove NO X as well as particulate matter, we have examined the catalytic reduction of NO X with soot in the presence of ox

To clarify the N2 formation mechanism during the C−N2O reaction, the detailed nitrogen mass balance was established. It was also attempted to reveal the role of surface nitrogen species in this reaction by using isotope gases. In contrast to the ca

Catalytic hydrocracking of Orinoco tar over metal-free USY zeolite was studied using a high pressure fixed bed reactor to produce chemical feedstocks like BTX. The effects of reaction temperature and catalyst on the product distribution were examined

The reactions of NO with pure carbons, phenol-formaldehyde resin char and amorphous 13C, were examined at 850°C in the presence of O2. Previous studies revealed that some of the nitrogen in NO was trapped on the carbon surface, and it plays an impor

The reaction between nitrogen oxides and carbon generates nitrogen-containing complexes on the carbon surface. The use of X-ray photoelectron spectroscopy allowed the characterization of these surface complexes. Five distinct structures have been dis

The role of O- and N-containing surface species in the course of NO reduction over phenol-formaldehyde resin char and amorphous 13C was investigated. The presence of O-containing complexes on the char surface was shown to increase the reactivity towa

The miscibility of bitumen-coal tar mixtures has been investigated. Bitumen-coal tar mixtures containing 10 to 50 wt% of coal tar were examined by differential scanning calorimetry and optical microscopy to determine the threshold of miscibility. A s

The behaviour of bitumen was investigated by differential scanning calorimetry. It is shown that two glass transitions take place after cooling at constant rate. The magnitude and temperature of these transitions depend on the cooling rate. At low co

The influence of polar compounds like phenols and pyridine-type bases on the morphology and glass transition of coal tar is investigated. A coal tar sample is separated into various fractions which thereafter are recombined progressively in order to
