Background technology
Petroleum resources is exhausted day by day in recent years, and rising violently of oil price promoted the development of international biofuel industry, caused the attention of national governments.Become new forms of energy development and hot of research and development as the nontoxic sunlight green energy resource one biological diesel oil of cleaning, it is the fine oil substitutes.Biofuel is the mixture of the short-chain alkyl fatty acid ester that generated by transesterification reaction by animal-plant oil and low-carbon alcohol.Greatly develop biofuel to reducing topsoil, alleviate environmental stress, preserve the ecological environment, promote agricultural and manufacturing development that considerable active effect is arranged.
Preparing biodiesel by ester interchange has overcritical catalysis method, enzyme catalysis method, acid catalyzed process, base catalysis method at present.Traditional ester exchange process is to be the homogeneous phase technology of catalyzer with liquid acid or alkali, homogeneous acid catalyst such as sulfuric acid, phosphoric acid or hydrochloric acid, homogeneous phase alkaline catalysts such as NaOH, KOH etc., these catalyzer not only use up aftertreatment and get up cumbersome, equipment is also had corrosive nature, and the discharging of spent acid salkali waste causes severe contamination to environment.And the ease of use of polymer heterogeneous catalyst, environment friendly, recyclability has caused the special concern of domestic and international chemical industry to the zero corrodibility of equipment.Anton A.Kiss etc. has reported
Two kinds of acidic resins catalysis for preparing biodiesel oil (Anton A.Kiss of NR50 and Amberlyst-15, Alexandre C.Dimian and Gadi Rothenberg, Journal of American Society Chemistry, 2006,348,75-81), this method has been simplified the sepn process of product, equipment there is not corrosion, and reusable edible, but the reaction times is longer.Yang Ru etc. disclose the method (CN101108338) that a kind of absorbent resin carrier solid alkali is made biodiesel, and deficiency is that Preparation of Catalyst is loaded down with trivial details, and have certain alkali loss.Zhu builds good grade and discloses and a kind ofly prepare method of bio-diesel oil (CN101168682) in trickle bed neutral and alkali resin catalysis grease alcoholysis reaction, improved rate of mass transfer, avoided the subsequent handlings such as separation of catalyzer, but this method causes the waste of methyl alcohol, and the equipment complexity, not easy to operate.Yijun Liu etc. has reported preparation (the Yijun Liu of quaternary amine I type strongly basic anion exchange resin (A26) catalysis biological diesel oil, Edgar Lotero, James G.Goodwin Jr.and Changqing Lu, Journal of catalysis, 2007,246,428-433), this method has excellent catalytic effect, avoids producing advantages such as saponification.The exchange capacity of quaternary ammonium II type strongly basic anion exchange resin is bigger than I type, and regenerative power has the better application prospect than I type height in the preparation technology of biofuel.
Summary of the invention
The present invention proposes to have the reactive behavior height with the exchange resin catalyzed preparation biofuel of quaternary ammonium II type basic ion, and speed of response is fast, saponification can not take place in the reaction conditions gentleness, to not corrosion of equipment, product postprocessing is easy, and catalyst system therefor can reuse advantage such as therefore can reduce production costs.
The present invention proposes a kind of preparation method of biofuel, it is characterized in that described method is: with quaternary ammonium II exchange resin catalyzed vegetables oil of type basic ion and low-carbon alcohol generation transesterification reaction, reaction solution obtains the product biofuel through separation.
According to described preparation method of bio-diesel oil, it is characterized in that the structure of described quaternary ammonium II type basic ion exchange resin is:
