Apparatus and process for production of liquid fuel from biomass

Abstract

An apparatus and process for efficient synthesis of liquid fuel from biomass, such as plant matter, as a raw material. Liquid fuel synthesizing apparatus (1) is comprised of a serial multistage arrangement, along gas flow, of reactor (2) with a catalyst incorporated therein, cooler (3) for cooling of synthesized gaseous matter and extracting of liquid fuel and temperature regulation means (7) for regulating by heat exchange any unreacted gas after recovery of liquid fuel to a reaction temperature suitable for liquid fuel gas synthesis. The temperature regulation means (7) and the reactor (2) are disposed in parallel relationship inside thermostatic chamber (8) of heat insulation structure surrounded by a heat insulating material. With respect to the cooler (3), it is disposed in isolation from the thermostatic chamber (8).

Description

technical field [0001] The present invention relates to a device and a manufacturing method for synthesizing liquid fuel by using biomass such as plants as raw materials. Background technique [0002] Considering the urgency and depletion of oil resources, mainly by CO 2 The importance of the selection and development of alternatives to global warming cannot be overemphasized. In the case of a long-term outlook, the production of synthetic fuels using biomass as a raw material is highly expected from the viewpoint of the quantity in view of the huge demand thereof. [0003] As in the case of using natural gas and coal as raw materials, biomass can be used as raw materials, and synthetic gas (H 2 +CO), using methanol, DME (methyl ether) or F-T (Fischer-Tropsch) to obtain liquid fuels such as hydrocarbons. As the advantages of these liquid fuels synthesized from biomass, the following advantages can be listed: (1) they are fuels that store solar energy and can be recycled; ...

AI Technical Summary

Problems solved by technology

However, in the present invention, although the same operation is repeated in multiple stages, since the reactor has multiple stages, it is not easy to adjust these entire stages to an appropriate temperature for the reaction.

In addition, since the reactors are arranged vertically from top to bottom, when replacing the catalyst, the entire reactor must be disassembled in the vertical arrangement, which takes time for maintenance and causes problems in operation planning.

And, because the temperature control instrument is juxtaposed in the whole section, therefore, there is the shortcoming of complex device

[0009] In addition, in the case of synthesizing liquid fuel gas from synthesis gas obtained by gasifying biomass, for example, in the case of synthesizing methanol gas, H in the synthesis gas 2 and CO 2 The higher the concentration of methanol gas, the higher the yield of methanol gas. When their concentration is low, methanol gas cannot be synthesized efficiently
