Description
Technical field
A kind of method of preparing Floating agent for coal with animal-plant oil and waste grease of the present invention, belongs to the utilization of renewable energy solar energy and waste grease, the preparation of Floating agent for coal and Application Areas thereof.Be specifically related to a kind of renewable sun power that utilizes environmental protection, take animal-plant oil or waste grease as raw material, by controlling the type of photocatalyst material, under sunlight, UV-light or visible light photocatalysis effect, prepare hydro carbons, lipid acid, Floating agent for coal that Ester ratio is different.
Background technology
The main component of animal-plant oil is fatty acid triglyceride, with C
12～C
22be that main alkyl chain and ester group form, and sulphur and nitrogen element content few.Along with the raising day by day of standard of living and the fast development of food and restaurant service industry, produce a large amount of waste greases, wherein, small part is sent to chemical plant and produces lipid acid and soap, and most waste grease is refined by improper channel processing by illegal molecule and becomes " edible oil " market that circulates, again walk to put on the dining table, because animal-plant oil can produce the carcinogenic substances such as hypertoxic flavacin, benzopyrene through high oxidation, this produces grave danger to the mankind's health and environmental safety.Therefore to the comprehensive utilization of waste grease, be, to benefit one of the healthy living of the whole society and Economic Sustainable Development Strategy.
At present, the regeneration of waste grease mainly comprises following several respects: the one,, by fatty acid soaps and glycerine that after glycerine fatty acid three esters or fatty acid saponification, generating washing is used, or decolouring and saponification after product are directly as the raw material (CN102586042A, CN202440485U) of producing washing powder; The 2nd,, the waste grease of take is prepared biological demulsifying agent as carbon source through fermentation, and it is the emulsion splitter that carbon source produces that its output and demulsification are better than take paraffin, and product be Lipopeptide Biosurfactants (Liu Jia etc. environmental science, 2009,30 (6): 1779-1784.); The 3rd,, thermo-cracking or catalytic pyrolysis are prepared low-carbon alkene class industrial chemicals (CN101314748, CN100546956C, CN103130600); The 4th,, waste grease and low-carbon alcohol are carried out to transesterification under acid base catalysator effect, washing dry preparing biological diesel oil, gasoline and aviation kerosene (CN101294096A, CN102660335A, CN102994138A); Etc..The regeneration comprehensive of the waste grease of above-mentioned report utilizes and in technical scheme, shows following deficiency: the one,, the waste grease usage quantity of producing soap class living organism emulsion splitter is less, cannot solve generation a large amount of waste greases utilize problem; The 2nd,, production method and the technological principle of biofuel, gasoline and aero oil are feasible, but need be greater than 96.5% as demanded fuel fatty acid methyl ester, cause that high purity cost is high, energy consumption is large, complex process etc., the purposes of low-purity is restricted, causes produce market Difficulty etc.Therefore, develop a kind of comprehensive utilization technique and new purposes thereof of novel waste grease extremely urgent.
Since titanium dioxide in 1972 is proved to be and has photocatalysis performance, what photocatalysis oxidation technique was considered to solve persistent organism pollution problem has one of technology of application prospect most, is at home and abroad widely studied in the last few years.Research shows, the main active specy oxyradical of photochemical catalysis (O
