介绍中国石化抚顺石油化工研究院以减三线馏分油、减三线脱蜡油和减三线蜡下油替代润滑油基础油调制凡士林原料并经高压一段串联加氢制取医药白凡士林的试验情况。结果表明,减三线馏分油、减三线脱蜡油和减三线蜡下油可以替代润滑油基础油调制物理性质符合产品要求的凡士林原料。减三线馏分油和减三线蜡下油等含石蜡组分在凡士林原料配方中的含量应在合理范围,含石蜡组分含量过高会影响调和物的拉丝性。在试验条件下,以减三线馏分油、减三线脱蜡油和减三线蜡下油为调和组分调制的凡士林原料,可以采用高压一段串联加氢工艺生产符合GB1790-2012医药凡士林标准的白凡士林产品。  相似文献

The apolar and hydrophobic jojoba molecule was made more hydrophilic by the incorporation of primary amino groupsvia the introduction and subsequent reduction of azido groups. The azides were obtained by the substitution of bromine or a mesylate group introduced into the jojoba oil molecule; by opening of the epoxide ring in epoxy jojoba; or by the addition of bromoazide to the double bonds of jojoba.  相似文献

Studies of the batch hydrotreatment of shale oil from the Rundle (Queensland, Australia) deposit were carried out, and the suitabilities of three commercial catalysts based on Ni-Mo, Co-Mo and Ni-W were evaluated in terms of nitrogen removal and hydrocracking ability. All catalyst systems were effective for olefin saturation and removal of labile N and O compounds (nitriles and ketones). Both the Ni-Mo and Co-Mo systems removed significant amounts of pyridines and quinolines, but failed to convert the less basic pyrrolic material. The Ni-Mo system gave the most satisfactory performance in this area. The Ni-W catalyst behaved poorly. Only limited hydrocracking was observed, and this was confined to cracking of n-paraffins and alkyl side chains of aromatics. Polyaromatic structures were not cracked.  相似文献

Aromaticities determined by 13C n.m.r. are reported for five shale oil samples (Green River formation) prepared under widely different pyrolysis conditions. In the absence of high-pressure hydrogen, the total amount of aromatic carbon in the products is nearly twice that in the raw shale. This is true for a wide range of pyrolysis conditions, although the distribution of aromatic carbon between the oil and carbonaceous residue changes. High-pressure hydrogen appears to inhibit both the formation of additional aromatic carbon during pyrolysis and the coking of aromatic oil. An improved kerogen decomposition mechanism is reported that accounts for these effects and provides for changes in the aromaticity of the liquid product with pyrolysis conditions. Further work is necessary to make it quantitative and account for gas formation.  相似文献

One of the major difficulties in using crude vegetable oils as substitute fuels in diesel engines is their relatively high viscosities. Increasing the temperature of the crude vegetable oil, blending it with diesel oil, or the combination of both offers a simple and effective means of controlling and lowering the viscosities of vegetable oils. This work reports viscosity data, determined with a rotational bob-and-cup viscometer, for crude palm oil and cononut oil blended with diesel oil over the temperature range of 20–80°C and for different mixture compositions. All the test oil samples showed a time-independent newtonian type of flow behavior. The reduction of viscosity with increasing liquid temperature followed an exponential relationship, with the two constants of the equation being a function of the volume percentage of the vegetable oil in the mixture. A single empirical equation was developed for predicting the viscosity of these fuel mixtures under varying temperatures and blend compositions.  相似文献

The cis‐trans isomerizations undergone by linoleic acid during industrial deodorization and/or physical refining of edible fats were studied in an experimental discontinuous pilot plant of 250 kg using nitrogen as stripping gas in place of steam. For each oil, the expression of the analytical results has been made as molar fraction, which is kinetically equivalent to making an abstraction from the other components in the reaction bulk and assumes they do not take part in the isomerization. The kinetic constants for the formation of the acids C18:2(9c,12t), C18:2(9t,12c) and C18:2(9t,12t) were determined. The equations and values obtained justify that the reaction orders studied are zero (or can be considered zero) for the time taken in an industrial deodorization and/or physical refining of edible fats. The analytical method used is appropriate for direct application of the results in industry.  相似文献
