Description
Technical Field
The invention relates to a novel method for directly preparing naphthenic aviation fuel by taking aromatic oxygen-containing waste plastics as raw materials through hydrodeoxygenation. The supported metal-metal oxide catalyst is adopted to realize the direct hydrodeoxygenation of the aromatic oxygen-containing waste plastics under mild conditions, and a series of naphthenic aviation fuels are obtained with high yield. Compared with the prior hydrodeoxygenation method for aromatic oxygen-containing waste plastics, the method has the advantages of simple operation process, low energy consumption, low cost and the like.
Background
With the increasing use of plastic articles by humans, waste plastic has become a global problem. Polycarbonate (PC), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyphenylene oxide (PPO), and the like, which are aromatic oxygen-containing plastic products widely used today, are mainly formed by polymerizing monomer molecules through ester group or ether bond linkage. Currently, the main method for disposing of these waste plastic products is to recycle them mechanically, but this method's deterioration of the plastic quality limits the wide application of the method, for example, only 7% of PET is recycled. Therefore, the method has positive significance for the development of environmental protection and recycling economy in order to reduce the discharge of plastics into the environment as much as possible and simultaneously degrade and convert the waste plastics into high-value chemical products.
Aviation fuel is liquid fuel with great demand in international transportation industry, and cycloalkane is an important component of aviation fuel and has very high economic value. At present, the aviation fuel is mainly prepared by taking fossil resources (coal and petroleum) as raw materials. In recent years, with the decrease of petroleum resources and the rising of international crude oil prices, the price of aviation fuel is also gradually increased. Waste plastics are used as wastes of fossil resource using terminals, and can be used as a novel resource for synthesis and preparation of aviation fuels. The aromatic oxygen-containing waste plastics can be used for preparing high-value naphthenic aviation fuel by a hydrodeoxygenation method, and the realization of the process technology not only has important significance for upgrading utilization of the waste plastics, but also can reduce the dependence on fossil resources to a certain extent.
The study on preparation of naphthenic aviation fuel by catalyzing PET and PC by adopting a two-step method is reported in the laning topic group of the major junctional complex in 2019 [ Green chem.,2019,21, 2709-2719; green chem.,2019,21,3789-3795 ]; the path includes: alcoholysis PET or PC is methyl terephthalate or bisphenol A monomer and hydrodeoxygenation monomer is cycloparaffin fuel; wherein the hydrodeoxygenation catalyst is a mixed catalyst of Ru-Cu/SiO2 and Pt/C and H-beta, and the yield of the naphthenic hydrocarbon can reach more than 80%. In order to improve the process economy, the subject group proposes that a Raney nickel and USY zeolite mixed catalyst is used for preparing naphthenic hydrocarbon and aromatic hydrocarbon fuels (C6-C15) through alcoholysis and hydrogen transfer hydrodeoxygenation, and the yield can reach 80%; however, the yield of saturated cycloalkanes is only 30% [ Green chem.,2021,23, 912-. In order to further improve the yield of target products, the subject group realizes the preparation of the dicycloalkane fuel by using a mixed catalyst of Rh/C and USY zeolite and performing one-pot water-phase hydrodeoxygenation of PC and real PC waste plastics (DVD compact discs) under the hydrogen conditions of 200 ℃ and 3MPa, wherein the yields are respectively 94.9 percent and 86.9 percent [ Green chem. 2021,23, 3693-. However, these processes require higher reaction temperatures (200 ℃) in the hydrodeoxygenation step; the most important reason is due to the low activity of the hydrodeoxygenation catalyst. Therefore, the supported metal-metal oxide hydrodeoxygenation catalyst designed and prepared by the invention can realize complete hydrodeoxygenation of aromatic oxygen-containing waste plastics at low temperature (160-200 ℃), so that the cycloparaffin aviation fuel can be prepared at high yield. In addition, the solid acid cocatalyst is added, so that the hydrodeoxygenation activity of the supported metal-metal oxide catalyst can be remarkably improved, and the efficiency of converting the aromatic oxygen-containing waste plastic into the naphthenic aviation fuel is improved.
