摘要/Abstract

摘要： 采用F-T蜡对石蜡进行调合, 分别考察了F - T蜡质量分数对4 6#和5 8#石蜡的影响。结果表明, F -T 蜡的加入可以显著提高石蜡熔点, 在F-T蜡质量分数从0. 0 5%增加到3 0. 0 0%时, 4 6# 与5 8# 调合蜡滴熔点分别从 72.4、 88.4℃下降到44.4、 62.4℃; 随着F - T蜡质量分数的增加, 调合蜡的滴熔点与针入度不断下降, 即F-T蜡的质量分数与滴熔点和针入度成反比。对调合蜡的结晶结构进行分析, 结果表明, 由于调合蜡中非异构烷烃含量高, 所以它的晶体结构为斜方点阵排列结构的长针状蜡晶, 与天然石蜡结晶不同, 其组成更加复杂。

关键词: F-T蜡, 滴熔点, 针入度, 结晶结构

Abstract: Paraffin wax was blended with F-T wax. The effects of the mass fraction of F-T wax on paraffin 46^# and 58^# were investigated respectively. The results show that the addition of F-T wax can significantly increase the melting point of paraffin, when the mass fraction of F-T wax increases from 0.05% to 30.00%, the melting point of 46^# and 58^# blended wax drops from 72.4 ℃ to 44.4 ℃, and drops from 88.4 ℃ to 62.4 ℃, respectively. With the increase of the mass fraction of F-T wax, the melting point and penetration of blended wax decrease continuously, that is, the mass fraction of F-T wax is inversely proportional to the drop melting point and penetration. The analysis of the crystalline structure of the blended wax shows that, the content of non-isoparaffins in the blended wax is higher. So its crystal structure is an array of inclined lattice arrangement of the long needlelike wax crystals, and the natural paraffin crystallization is different with others, which composition is more complex.

Key words: Fischer-tropsch wax, Drop melting point, Penetration, Crystal structure
