Abstract
A biomass-based long-chain alcohol ether oxygenated additive and a preparation method and application thereof are disclosed. The additive used agricultural and forestry wastes as raw materials, and has a general chemical formula of R—(O—C)—R—OH. The preparation method includes the following steps: step 1, performing drying pretreatment on biomass raw materials, performing rapid pyrolysis under an inert atmosphere to obtain a pyrolysis product containing water, gases, water-phase bio-oil and oil-phase bio-oil, separating out the water-phase bio-oil and performing catalytic hydrogenation on the water-phase bio-oil to obtain polyols; step 2, performing catalytic dehydration on the polyols obtained in step 1 under a basic catalyst system to obtain epoxyalkane; and step 3, making the epoxyalkane obtained in step 2 and methanol undergo a reaction under a molecular sieve catalyst and removing the solid catalyst by separation to obtain the long-chain alcohol ether oxygenated additive.
