A novel approach to produce biomass-derived gasoline is the hydrolysis of 2,5-dimethylfuran (DMF) to produce 2,5-hexanedione followed by base-catalyzed intramolecular aldol condensation of this product to form 3-methylcyclopent-2-enone (MCP). By proper choice of catalysts and conditions, MCP yields of 98% can be achieved. We further show that hydrogenation of MCP over Pt/NbOPO4 gives methylcyclopentane with virtually quantitative yields. Methylcyclopentane is an attractive gasoline substitute for ethanol, since its octane number is similar to ethanol and its gravimetric energy density is 58% higher. This journal is

Paragraph 0048-0052, (2021/01/20)
The invention provides a method for preparing a cyclopentanone compound by aqueous phase hydrogenation rearrangement of furfural and a derivative thereof, and belongs to the field of catalytic conversion of biomass resources. Specifically, a supported Ni3P catalyst converts furfural and a derivative thereof into a cyclopentanone compound in an H2 atmosphere, wherein the supported Ni3P catalyst provided by the invention is prepared by a deposition-precipitation chemical plating method. According to the invention, the catalyst obtained by the method is high in dispersity and small in particle size, and has high furfural and derivative conversion rate and cyclopentanone compound selectivity in the reaction of preparing cyclopentanone and derivatives thereof by aqueous phase hydrogenation rearrangement of furfural and derivatives thereof; and the furfural conversion rate and the cyclopentanone selectivity respectively reach 89.1% and 81.3% after the reaction is carried out for 1 hour at the pressure of 4 MPa H2 and the temperature of 160 DEG C.
Efficient Palladium(0) supported on reduced graphene oxide for selective oxidation of olefins using graphene oxide as a ‘solid weak acid’

, p. 73 - 78 (2019/02/06)
Selective oxidation of olefin derivatives to ketones has made innovative development over palladium(0) supported on reduced graphene oxide. Compared to traditional Wacker oxidation, the novel method offers an economical and environment-friendly option by using graphene oxide (GO) as a ‘solid weak acid’ instead of classical homogeneous catalysts like H2SO4 and CF3COOH. X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscope and transmission electron microscopy images of Pd0/RGO showed that the nanoscaled Pd particles generated at the flake structure of reduced graphene oxide. Under optimized condition, up to 44 kinds of ketones with different structures can be prepared with excellent yields.
