Abstract

The invention relates to a heavy fuel oil asphaltene dispersant. According to the technical scheme, the heavy fuel oil asphaltene dispersant is prepared from the following raw materials in parts by weight: 10-50 parts of ester, 20-60 parts of alkyl benzene sulfonic acid, 5-20 parts of fatty alcohol-polyoxyethylene ether and 10-30 parts of solvent, wherein the ester is one of carboxylic esters of RCOOCH3, R is straight-chain alkyl and the quantity of carbon atoms is 10-16; the alkyl benzene sulfonic acid is one of RSO3H, wherein R is an alkyl carbon chain and the quantity of carbon atoms is 12-18; the general formula of the fatty alcohol-polyoxyethylene ether is RO(CH2CH2O)mH, wherein R is straight-chain alkyl the quantity of carbon atoms is 10-18 and m is 7-11; the solvent is absolute ethyl alcohol. The heavy fuel oil asphaltene dispersant has the beneficial effects that the problem of sedimentation of marine fuel oil asphaltene can be solved, not only can sedimentation of the asphaltene in the fuel oil be prevented, but also the settled asphaltene in the fuel oil can be dispersed; meanwhile, the marine fuel oil asphaltene dispersant provided by the invention has the characteristics of being good in dispersibility, low in cost and simple and convenient to use.

Description

technical field [0001] The invention relates to a heavy fuel oil asphaltene dispersant, in particular to a heavy fuel oil asphaltene dispersant capable of effectively reducing and controlling the aggregation and sedimentation of asphaltene during fuel oil blending and use. Background technique [0002] With the continuous rise of international crude oil prices and the fierce competition in the shipping industry, in order to reduce energy consumption costs, heavy fuel oil for ships has become the general trend. Due to the high density, high viscosity and high asphalt content of heavy fuel oil, and after repeated processing, it will become larger and larger in the residual oil, unstable, and easy to precipitate and settle during use and blending, forming sludge or sediment. In the process of storage and lightering, the oil outlet pipe, filter and oil separator of the oil tank are blocked. In the process of use, it is easy to cause poor atomization, difficulty in ignition, insu...
