煤焦油沸腾床加氢制备180号船用燃料油调合组分

对中温煤焦油全馏分进行沸腾床加氢处理，将加氢产物经分馏切割出大于355 ℃的馏分或大于400 ℃的馏分，对两者的性质进行分析，并考察大于400 ℃馏分与水上油、煤柴油、页岩油调合的相容性和储存安定性。建立了梯度黏度法，用于评价燃料油的储存稳定性。结果表明：大于355 ℃馏分可直接作为180号船用燃料油；＞400 ℃馏分与水上油、煤柴油、页岩油具有较好的相容性，可以作为180#船用燃料油的优质调合组分，在大于400 ℃馏分、水上油、页岩油和煤柴油的比例（质量分数）分别为67%，12%，10%，11%时，能够调合得到满足GB/T 17411标准要求的180号船用燃料油。

PREPARATION OF 180# MARINE FUEL OIL BY EBULLATED-BED HYDROTREATMENT OF MEDIUM TEMPERATURE COAL TAR

The ebullated-bed hydrotreated products of medium temperature coal tar were distilled to get fractions of >355 ℃ and > 400 ℃, which then were analyzed for their compositions and properties. The compatibility and storage stability of the blended fuel oils, which were prepared by blending of > 400 fraction, the floating oil on the water, coal diesel and shale oil, were studied. The results show that the > 355 ℃ fraction can directly be used as 180# marine fuel oil; > 400 ℃ fraction has a good compatibility with floating oil, coal diesel and shale oil and can be used as a high quality blending component of 180 # marine fuel oil. The 180# marine fuel oil can be prepared by blending > 400 fractions, floating oil, shale oil and coal diesel with a ratio of 67%, 12%，10% and 11%, respectively. The product meets the national standard GB/T 17411 of marine fuel oil.
