利用地沟油制备新型燃料及其稳定性研究

Research on Producing New Fuel from Ditch Oil

本文提出一种以废弃地沟油、水煤浆、不同煤样以及各种添加剂为原料制备地沟油水煤浆的方法。通过实验优化得到稳定的添加剂配方:单甘脂(30%),司盘20(45%),CMC(3%),黄原胶(2%),十二烷基苯磺酸钠(20%)。然后利用这组配方以地沟油、水煤浆和不同煤粉为原料制备地沟油水煤浆,并研究其稳定性和燃烧性。结果表明:无烟煤1和红旗烟煤表现较好,具有较高的热值和稳定性,制备出的产品具有高稳定性、粒度细、灰分低、热值高的特点,可用于水煤浆点火、代替柴油用于柴油机以及各种小型燃油锅炉,是一种应用前景广阔的新能源。

A method of producing ditch oil and coal water mixture was presented, the raw materials were aban- don ditch oil, coal water mixture, different coal samples and various additives in this paper. Through the optimi- zation we obtained stable additive formulation ： monoglyceride （30%） , span 20 （45%）, CMC （3%）, xanthan gum （2%） and sodium dodecyl benzene sulfonate （20%）. Then used this formulation, the materials were ditch oil, coal water mixture and different coal samples, to produce the mixture, and the mixture stability and combus- tion were studied. It showed that anthracite （!） and Hongqi coal performance were better, with higher calorific value and stability. The products had high stability, , fine granularity, low ash content and high calorific value. Those were coal water mixture ignition, instead of diesel oil for diesel engine and a variety of small oil fired boil- er, which was a new energy applied prospects broadly.
