Conclusions Technical-economic calculations have revealed the economic feasibility of and favorable outlook for commercial production of petroleum lubricating oils with viscosity indexes of about 100 from crude oils from the new Ust' -Balyk and Uzen' fields, the latter crude being highly paraffinic.Thus, the net operating cost and adjusted cost for production of high-viscosity-index oils from Ust'-Balyk and Uzen' crudes by the processing scheme used in USSR refineries is lower than for the production of oils with average viscosity indexes of 85–88 from Romashkino crude.Complete processing of the slack waxes and petrolatums to recover paraffin waxes and ceresins is a necessary condition for the economical production of lubricating oils from Uzen' crude.Translated from Khimiya i Tekhnologiya Topliv i Masel, No. 7, pp. 24–28, July, 1970. 相似文献

This study reports the essential oils chemical composition and antioxidant and antimicrobial potentials of the leaves of Phrynium pubinerve Blume and Thysanolaena latifolia (Roxb. ex Hornem.) Honda, which are used as natural packaging materials by ethnic groups in Xishuangbanna, southwest China. GC–MS analysis identified 46 and 21 components, representing 88.6% and 93.4% of the essential oils of P. pubinerve and T. latifolia, respectively. The major constituents for P. pubinerve were (Z)-3-hexen-1-ol (17.31%), (E)-2-hexenal (9.01%) and 1-hexanol (8.61%). The major constituents for T. latifolia were (Z)-3-hexen-1-ol (28.79%), phytol (12.30) and (E)-β-ionone (9.54%). Both the essential oils and ethanol extracts showed antioxidant activity in DPPH test (IC50 values = 192.47–706.07 μg/ml), ABTS assay (IC50 values = 35.54–134.97 μg/ml) and FRAP assays. The essential oils showed considerable antimicrobial activity against pathogenic bacteria and spoilage organisms, with MIC and MBC values in the ranges of 64–3072 μg/ml and 64–4096 μg/ml, respectively. The bioactivities of these two plant species validate the traditional use of these two plants, suggesting that both could be new sources of natural antioxidant and antimicrobial agents for the packaging, medical and functional food industries. 相似文献

The process of two-stage deasphalting of heavy resid with addition of used waste motor oil in the second stage is studied.
A technology has been developed for used oil regeneration using two-stage deasphalting process. The second stage deasphalted
oil can be used as the base oil. 相似文献
