Catalytic Steam Cracking

In this paper the influence of dispersed catalysts obtained in situ based on various metals (Mo, Ni, Fe, Co) has been studied on the yield and properties of liquid products in a slurry-reactorat a temperature of 425 °С and a pressure of 20 MPa. The most active catalytic compositions for the process of catalytic steam cracking of oil (Mo and Mo-Fe) were selected. In the presence of dispersed Mo and Mo-Fe catalysts the samples of the semisynthetic oils were produced. In the rectification process the gasoline, diesel, oil and residual fractions were allocated. The selected fractions were analyzed by physicochemical methods for a wide range of performance in comparison with the initial heavy oil. The efficiency of Mo-Fe catalysts for obtaining semisynthetic oil with an increased content of light fractions (i.b.p. – 360 °С) during the catalytic steam cracking of heavy oil was shown

Ru-Sn/TiO2 is an effective catalyst for hydrogenation of aqueous acetic acid to ethanol. In this paper, a similar hydrogenation process was investigated in a flow-type rather than a batch-type reactor. The optimum temperature was 170 °C for the batch-type reactor because of gas production at higher temperatures; however, for the flow-type reactor, the ethanol yield increased with reaction temperature up to 280 °C and then decreased sharply above 300 °C, owing to an increase in the acetic acid recovery rate. The selectivity for ethanol formation was improved over the batch process, and an ethanol yield of 98 mol % was achieved for a 6.7 min reaction (cf. 12 h for batch) (liquid hourly space velocity: 1.23 h−1). Oxidation of ethanol to acetic acid (i.e., the reverse reaction) adversely affected the hydrogenation. On the basis of these results, hydrogenation mechanisms that include competing side reactions are discussed in relation to the reactor type. These results will help the development of more efficient catalytic procedures. This method was also effectively applied to hydrogenation of lactic acid to propane-1,2-diol.
