Abstract

The invention belongs to the technical field of biological crude oil and preparation thereof, and particularly relates to biological crude oil prepared by co-liquefying algae and crude glycerine and a method for preparing the biological crude oil by co-liquefying algae and crude glycerine. The process of the method comprises the following steps of: preparing the biological crude oil by using a high-temperature and high-pressure reaction kettle and taking algae and crude glycerine as raw materials, wherein main control means are temperature, initial pressure and the weight ratio of algae to crude glycerine in an oil production process; after algae and crude glycerine are reacted as the raw materials, extracting, filtering, distilling and drying product residual oil to obtain the biological crude oil. Compared with a method for preparing the biological crude oil by hydrothermally liquefying the algae, the method disclosed by the invention enhances the yield of the biological crude oil from 23.0% to 38.7% and the HHV (High Heat Value) is more than 35 MJ / kg, by taking enteromorpha prolifera as an example; the obtained biological crude oil is black thick liquid, has good flowability and has the hydrocarbon compound content being as high as 45.6%. The method disclosed by the invention is energy-saving, environmental-friendly and easy to operate, not only can enhance the yield and quality of the biological crude oil, but also can sufficiently utilize the biomass resources.

Description

technical field [0001] The invention belongs to the technical field of bio-crude oil and its preparation, and in particular relates to a bio-crude oil prepared by co-liquefaction of algae and crude glycerin and a method thereof. Background technique [0002] With the development of the economy, global fossil fuel resources are increasingly depleted and the environment is deteriorating. In recent years, in order to solve the problem of resource shortage, people have been actively exploring alternative products of petroleum. Biomass has huge potential and is the only renewable energy source that can be converted into liquid fuels. [0003] As a kind of biomass thermochemical conversion technology, pressurized liquefaction uses the special effects of different solvents to convert biomass into liquid fuels or chemicals under certain temperature and pressure. The biomass conversion rate is high, and the requirements for equipment are relatively low. Biomass pressurized liquefa...
