Embodiment 1

[0029] Catalyst component: 50g of Y-type molecular sieve, 30ml of aqueous solution containing 0.8g of potassium bromide;

[0030] Preparation method: Immerse Y-type molecular sieve (produced by Wuxi Rongdeli Molecular Sieve Factory) with potassium bromide aqueous solution for 2 hours, and dry at 120°C for 2 hours to obtain a catalyst. The properties are shown in Table 1;

[0031] Potassium bromide in the catalyst is 1.21% of the weight of the catalyst in terms of bromine.

[0032] Utilize above-mentioned catalyzer to carry out the method for intermittent coal tar preparation fuel oil:

[0033] Add 300g of coal tar with a water content of 1wt% to the 1000ml autoclave device, and then add 4.5g of catalyst. After the autoclave is sealed, heat the autoclave to raise the temperature to 350°C, keep the temperature for 5 minutes, and then drop to room temperature Finally, the reaction product is taken out from the reactor, and then separated by distillation, and the fraction at 80-2...

Description

technical field [0001] The invention belongs to the field of coal chemical industry, in particular to a method for preparing fuel oil from coal tar. Background technique [0002] How to effectively utilize coal resources and make them meet the requirements of environmental protection has always been the research direction of various countries. Coal tar is one of the products of coal dry distillation and coal gas production. In my country, the deep processing of coal tar has attracted much attention in the 1950s and 1960s, and a lot of money and manpower have been invested in research. Due to the discovery of oil in Daqing, Liaoning, Shandong, Henan, Xinjiang and other places, since the 1960s and 1970s, my country's research and development of coal tar deep processing to produce high-quality and environmentally friendly liquid products has almost stagnated. Until the end of the 1990s, with the increasing consumption of petroleum resources worldwide and the increase in the p...
