Peng, Pai;Guo, Shenghui;Li, Linhu;Jin, Hui;Ge, Zhiwei;Guo, Liejin published 《Supercritical water gasification mechanism of polymer-containing oily sludge》 in 2021. The article was appeared in 《International Journal of Hydrogen Energy》. They have made some progress in their research.SDS of cas: 140-66-9 The article mentions the following:
In the offshore petroleum industry, polymer-containing oily sludge (PCOS) hinders oil extraction and causes tremendous hazards to the marine ecol. environment. In this paper, an effective pretreatment method is proposed to break the adhesive structure of PCOS, and the experiments of supercritical water gasification are carried out under the influencing factors including residence time (5-30 min) and temperature (400-750 °C) in batch reactors. The increase of time and temperature all show great promoting effects on gas production Polycyclic aromatic hydrocarbons, including naphthalene and phenanthrene, are considered as the main obstacles for a complete gasification. Carbon gasification efficiency (CE) reaches maximum of 95.82% at 750 °C, 23 MPa for 30 min, while naphthalene makes up 70% of the organic compounds in residual liquid products. The highest hydrogen yield of 19.79 (mol H2/kg of PCOS) is observed in 750 °C for 25 min. A simplified reaction pathway is presented to describe the gaseous products (H2, CO, CO2, CH4). Two intermediates are defined for describing the reaction process bases on the exhaustive study on organic matters in residual liquid products. The results show that the calculated data and the exptl. data have a high degree of fit and tar formation reaction is finished within 10 min. And 4-tert-Octylphenol (cas: 140-66-9) was used in the research process.
4-tert-Octylphenol(cas: 140-66-9) is a common environmental pollutant showing weak estrogenic effects.SDS of cas: 140-66-9 It has been shown to cause harm to vertebrate male reproductive systems.
