Problems solved by technology

However, the cheap large-scale preparation of HMF is one of the bottlenecks restricting the development of this process
In addition, these studies, without exception, used expensive and difficult to transport commercial H 2 As a source of reactive hydrogen, the industrial application of these catalytic processes is greatly limited
[0003] In conclusion, the prior art has the problems of severe C-C bond breakage, low selectivity of liquid alkanes and low energy efficiency in the process of preparing liquid alkanes by aqueous phase reforming of biomass derivatives

Embodiment Construction

[0032] The implementation of the specific embodiments is as follows, and the specific embodiments are listed in the table.

[0033] Batch reaction: the biomass derivative aqueous solution, C 1 ~C 6 Alcohol and catalyst are put into a stainless steel high-pressure reactor with a glass liner, sealed, heated to the required temperature under rapid stirring, and stopped after 0.5 to 60 hours of reaction. After cooling, separate liquid to obtain the corresponding liquid alkane. The mass concentration of biomass derivatives is 1-66%, C 1 ~C 6 The weight ratio of alcohol to biomass derivative is 0.2-5, the weight ratio of biomass derivative to catalyst is 1-100, the reaction temperature is 180-300 DEG C, and the reaction pressure is autogenous pressure.

[0034] Fixed bed reaction: put 0.2-2g of catalyst into a stainless steel tubular reactor with an inner diameter of 6mm and a length of 20mm, and fill the rest with 40-60 mesh quartz sand to reduce dead volume. Put the reaction t...

Abstract

The invention relates to a method for preparation of hydrocarbon and a prepared hydrocarbon composition. The problems existing in the prior art, such as severe C-C bond cleavage, low liquid alkane selectivity and low energy efficiency by a biomass derivative aqueous-phase reforming preparation technology of liquid alkane, are mainly solved. The above problems are greatly solved by the technical scheme of carrying out a water-phase reforming reaction on a biomass derivative and C1-C6 alcohol in the presence of a catalyst. The method can be used for industrial production of biomass derivative preparation of liquid alkane.

Description

technical field [0001] The present invention relates to a method for preparing hydrocarbons and the hydrocarbon composition prepared therefrom. Background technique [0002] With the depletion of fossil resources and a series of environmental and climate problems caused by the excessive use of fossil energy, it has become an urgent task to gradually replace fossil energy with renewable green energy. Biomass resources are currently the only renewable organic carbon source, and they are cheap and readily available. The preparation of liquid fuels and fine chemicals from biomass and its derivatives has attracted extensive attention from chemists at home and abroad in recent years. In 2004, the Dumesic research group at the University of Wisconsin reported for the first time that renewable C 1 -C 6 Alkanes (Angew. Chem. Int. Ed. 2004, 43, 1549-1551). This process is realized in two steps on a noble metal-supported solid acid bifunctional catalyst. First, sorbitol is reforme...
