example 1

[0039] Example 1: Solar energy decomposes substitute liquid fuel without heat recovery device. Please combine figure 2 , The present invention is composed of a solar heat collector, a catalytic reactor, a heat medium circulation system and other auxiliary equipment.

[0040] The heat medium storage tank 5, the heat medium stored in it is heat conduction oil with an operating temperature above 200°C, which is sent to the absorber 9 of the solar heat collector 8 through the heat medium pump 7 and the pipeline 21, and receives heat from the solar heat collector 8 The flow of the heat medium can be controlled through the valve 10; the heat medium is heated to 180°C to 300°C, and enters the shell side of the catalytic reactor 3 through the pipeline 22 at the lower part of the catalytic reactor 3, and the reaction in the catalytic reactor 3 The temperature is maintained at 160-280° C., and then enters the upper portion of the preheating evaporator 2 from the upper part of the cata...

example 2

[0042] Example 2: The solar energy decomposition substitute liquid fuel has a heat recovery device. combine image 3 , vs. figure 2 It can be seen that the main difference between Example 2 and Example 1 is that the heat medium at 180°C to 300°C from the absorber 9 enters the catalytic reactor 3 through the pipeline 22 to release heat, and returns directly to the heat medium from the upper part of the catalytic reactor 3 through the pipeline 27 The storage tank 5 completes the circulation of the heat medium.

[0043] At the same time, the decomposition product from the catalytic reactor 3 enters the upper part of the preheating evaporator 2 through the pipeline 28 to provide the vaporization heat of the feed and the heating heat to 160-280°C. The decomposition products after releasing heat and lowering the temperature enter the condensing separator 4 through the pipeline 29 at the lower part of the preheating evaporator 2 to be condensed and separated.

Abstract

A method for converting the solar energy to the chemical energy of fuel features that the solar energy is used for the reaction of decomposing methol, bimether, etc into CO and H2. Its apparatus is composed of a light gathering solar heat collector for heating the thermal medium, a catalytic reactor containing solid catalyst connected to said solar heat collector for receiving heated thermal medium, a preheating evaporator connected to catalytic reactor and raw material tank, and a condensing separator connected with catalytic reactor and preheating evaporator for separating the resultant.

Description

technical field [0001] The invention relates to a method for converting solar energy into fuel chemical energy. [0002] The invention also relates to an energy conversion device for implementing the above method. In detail, it relates to the integration of a dish solar heat collector and a substitute liquid fuel decomposition catalytic reaction device, and the two together with their respective auxiliary systems constitute a solar thermochemical conversion device. The device of the present invention can realize the complementarity of solar energy and conventional energy. Specifically, the device of the present invention can realize the cascade utilization of fuel chemical energy including methanol or dimethyl ether and the upgrading of low-grade solar thermal energy to high-grade fuel chemical energy. Using solar energy to convert liquid fuels into high calorific value clean gas synthetic fuels. Background technique [0003] The world's oil reserves and production have be...
