TL;DR: In this paper, a detailed kinetic mechanism for the pyrolysis and combustion of a large variety of fuels at high temperature conditions is presented, and the authors identify aspects of the mechanism that require further revision.
817 citations
TL;DR: In this paper, a controlled reduction in the effective dimensions of the catalyst pore openings, and/or channels, along with deactivation of acidic surface sites, has been proposed as a mechanism for the selective production of p-xylene.

TL;DR: A variant strain of Pseudomonas putida is discovered which is capable of growing in media culture containing more than 50% toluene or high concentrations of cyclohexane, xylene, styrene and heptanol, and it is shown that the relative toxicities of different solvents are determined by their polarities.
Abstract: TOLUENE, like many organic sovents, is highly biotoxic and kills most microorganisms at low concentrations (0.1% v/v). It is often used therefore to sterilize microbial cultures and lyse bacterial cells in the assay of bacterial enzymes1–3. The physiological basis of such solvent toxicity, however, remains poorly characterized. Although some microorganisms, including Pseudomonas4–6 , Achromobacter4 and Nocardia7 , can assimilate toluene, their toler-ance for the solvent is less than 0.3% (v/v). We report here the discovery of a variant strain of Pseudomonas putida which is capable of growing in media culture containing more than 50% (v/v) toluene or high concentrations of cyclohexane, xylene, styrene and heptanol. By studying this unusually tolerant strain we show that the relative toxicities of different solvents are determined by their polarities.

TL;DR: In this paper, a nitrogen purged static-bed batch reactor was used to pyrolyse 3 kg batches of shredded scrap tyres at temperatures between 450 and 600°C. The oils were trapped in a series of condensers and the derived gases analysed off-line by packed column gas chromatography.
