煤液化中油(220℃~260℃)馏分中含有大量的酚类化合物,其质量分数约20%~25%,其酚类化合物主要是由苯酚、(烷基)苯酚、(烷基)萘酚、(烷基)茚满酚和联苯酚等类型组成.考察了煤液化过程中反应温度、Mo系催化剂和添加高分油三种工艺条件... 煤液化中油(220℃~260℃)馏分中含有大量的酚类化合物,其质量分数约20%~25%,其酚类化合物主要是由苯酚、(烷基)苯酚、(烷基)萘酚、(烷基)茚满酚和联苯酚等类型组成.考察了煤液化过程中反应温度、Mo系催化剂和添加高分油三种工艺条件对煤液化中油馏分中不同酚类的影响.结果表明,升高反应温度和加入Mo系催化剂能增加煤液化油中总粗酚产率,而添加高分油方式则不太明显;另外,添加高分油方式可以促进高级酚类中间体发生裂解、脱烷基和脱羟基等二次反应向生成分子量更小、结构更简单的低级酚类进行转化,而通过Mo系催化剂的加入可以抑制部分高级酚类向低级酚类的转化. 展开更多

Domestic economic growth slowed down and supply exceeded demand in oil market in 2015, so the growth of refineries" processing volume was limited. Nevertheless, the gradual decontrol of market and the storage requirement under low oil price, crude oil imports hit a record high of 335.5 million tons, with the growth rate approximating 9%. Refined oil exports soared and imports decreased, which made China become a net refined oil exporter for the first time for 24 years, and net imports reached 6.22 million tons. Robust requirement on chemical raw materials propelled imported liquefied petroleum gas market to go on expanding. Imports exceeded 12 ,zillion tons in 2015, thus China leaped into the world's largest liquefied petroleum gas importer. In 2016, oil consumption growth would be kept at lower level. However, China would further decontrol crude oil import and refined oil export permits and put incremental storage capacity, into use. Therefore, crude oil imports would continue to rise up, and refined oil exports may hit a new historic high. hnported liquefied petroleum gas market will enter into a stage of stable growth after two years rapid development. 展开更多

The fuels that hardly pollute water body and atmospheric environment during burning are regarded as clean fuels. Liquefied Petroleum Gas (LPG), Compressed Natural Gas (CNG) and Liquefied Natural Gas (LNG) are three representative clean fuels that are widely used in the shipping industry. From both ecological and economic point of view, LNG is treated as the best fuels in shipping industry by the ship-owners and Chinese government. In this paper, the wide applications of LNG-powered ships are analyzed from three aspects, including the global energy source structure, economic demands and the formulation of international conventions. Also, the functions of relevant domestic policies on how to accelerate LNG-powered ships widely used in inland waters of Yangtze river, China are summarized. At last, the reasons of the use of LNG-powered ships in inland waters of China in recent years under the impulsion of various factors are discussed in the end. 展开更多
