摘要:
本文介绍了180#重油的降粘剂的选择,以及采用单因素优化法制备半纤维素重油的工艺研究,并且对半纤维素重油进行了热值、运动粘度和锅炉燃烧试验的考查。其优化工艺确立为重油与降粘剂的质量比为8:2,半纤维重油的HLB值为11.5,半纤维素溶液添加量为30%,乳化时间为30 min,乳化温度为常温。经检测制备的半纤维素重油弹筒热值为35.12 MJ/kg,与180#重油的37.22 MJ/kg相当,而运动粘度由180 mm2/s降低至28.5 mm2/s,粘度显著降低,解决了传统重油在储存、转运、燃烧过程中需要预热耗能的问题。

Abstract: In this paper, viscosity reducer of 180# heavy oil was chosen, and the preparation of hemicellulose crude oil was optimized using single factor method. Calorific value, kinematic viscosity and boiler burner test of hemicellulose crude oil were examined. The optimized conditions were as follows: the mass ratio of heavy oil and viscosity reducer was 8:2, the HLB of hemicellulose crude oil was 11.5, the addition amount of hemicellulose solution was 30%, the emulsification time was 30 min, and the emulsification temperature was room temperature. Barrel calorific value of hemicellulose crude oil was 35.12 MJ/kg, which was close to 37.22 MJ/kg of 180# heavy oil. Moreover, kinematic viscosity of hemicellulose crude oil dropped down from 180 mm2/s to 28.5 mm2/s. The obviously reduced viscosity solved the problem of preheating of heavy oil in its storage, transshipment and burning.
