Abstract

The invention provides a method for producing an environment-friendly blending component of marine fuel oil by adopting catalyst-free glycerol esterified hogwash oil. The hogwash oil is subjected to glycerol esterification to obtain biological fuel oil of which the acid value is less than or equal to 6.5mgKOH/g, the ash content is less than or equal to 0.1% and the pour point is less than or equalto 30 DEG C. The hogwash oil is subjected to catalyst-free heating and vacuum glycerol esterification to obtain the biological fuel oil which serves as the blending component of the marine fuel oil,and the method provided by the invention is simple in process, environment-friendly, pollution-free, low in production cost and easy to realize industrialization.

Description

technical field [0001] The invention relates to a method for producing environment-friendly marine fuel oil blending components by using catalyst-free glycerol esterification waste oil, and belongs to the fields of biomass chemical industry and renewable energy. Background technique [0002] The harm of waste oil to human health and environmental pollution is a huge hidden danger and a major social problem, and the chemical reuse of waste oil to make renewable energy is an effective solution. Biodiesel and aviation biokerosene are good ideas and methods, but the process is complicated, the cost is high, and the use of catalysts in the process also produces certain pollution treatment problems. However, waste oil can be converted into biofuels through non-catalyst, heating, and vacuum glycerol esterification. Used as a blending component of marine fuel oil, the process is simple, the method is environmentally friendly, no pollution is generated, the production cost is low, an...
