The invention provides a method for preparing liquid fuel using γ-valerolactone, the steps are as follows: phosphoric acid solution and γ-valerolactone are placed in a reaction tank, reacted at 220-260°C for 3-12 h, cooled to A liquid fuel is obtained at room temperature. The present invention uses phosphoric acid solution as a catalyst to convert γ-valerolactone in one step at a mild temperature (220-260°C) to produce light oil and heavy oil products with high calorific value, and the total oil yield can be as high as 33.5 wt%. This technology The technological process is simple, the operation is convenient, and the method has industrial application prospects. Compared with other technologies for catalytic conversion of γ-valerolactone to prepare high-grade oil products, catalytic conversion of phosphoric acid solution has the obvious advantages of no need to provide expensive hydrogen from outside, simple reaction process (one-step reaction), and mild temperature (temperature below 260°C). |
