Description

A Biomass Syngas Rotary Synthetic Diesel Device

technical field

The invention relates to a device for synthesizing diesel by rotating biomass synthesis gas, in particular to a device for synthesizing diesel by Fischer-Tropsch synthesis reaction using a rotating centrifuge under the action of a centrifugal force environment and a catalyst.

Background technique

At present, the Fischer-Tropsch synthesis method is used in the production of liquid fuels from biomass synthesis gas. Fischer-Tropsch synthesis has a history of more than 80 years. In recent years, the sustainability of energy and the environmental protection of fossil products have become more and more obvious. The development and promotion of environmentally friendly biomass energy has attracted the attention of various countries. Biomass raw materials can be used to prepare liquid fuels or high value-added chemicals through Fischer-Tropsch synthesis. has been widely recognized. However, the traditional Fischer-Tropsch synthesis products are mainly linear alkanes, olefins, a small amount of aromatics and aldols, and the product composition is complex. There are few light liquid hydrocarbons, and their product selectivity is poor. Except for heavy carbon hydrocarbons, which can achieve high selectivity, the selectivity of other products is not high. The use of different types of reactors, such as fixed bed, fluidized bed or slurry bed, has little effect on the selectivity of Fischer-Tropsch synthesis products.
