Abstract

The invention discloses a method used for kitchen waste oil co-pyrolysis extraction with microalgae liquidation multiproducts. According to the method, microalgae is subjected to hydro-thermal liquidation, and solid phase product and oil phase product obtained through hydro-thermal liquidation are extracted, the solid phase product is subjected to calcining at anoxic conditions, and immersion method is adopted for modification of the solid phase product so as to obtain a carbon based catalyst for filling in a fluidized bed reactor; the oil phase product and kitchen waste oil are mixed at a certain ratio, and an obtained product is introduced into the fluidized bed reactor for rapid cracking under the effect of the carbon based catalyst so as to obtain high quality bio-oil. According to themethod, full utilization of the microalgae hydro-thermal liquidation solid phase side product is realized, the crude bio-oil generated in hydro-thermal liquidation and waste oil are subjected to co-pyrolysis to produce the high value biological aviation oil, and oil yield is increased effectively.

Description

technical field [0001] The invention belongs to the technical field of biological oil production, and in particular relates to a method for co-pyrolysis and quality improvement of kitchen waste oil by participating in the co-pyrolysis of multiple products of microalgae liquefaction. Background technique [0002] With the development of science and technology, people's demand for fuel is increasing, and the utilization of clean energy is imminent. As a renewable and clean energy, biomass fuel can be a substitute for fossil fuels. Microalgae is an aquatic species. Breeding does not occupy arable land. It has rich varieties, strong reproductive ability, strong photosynthetic ability, and high oil content. Microalgae biomass fuel is transformed from microalgae raw materials through different thermochemical reaction processes. Come. Although microalgae have the ability to accumulate environmental and economic value such as oil and have great advantages over other biofuel raw ma...
