Technical Field

The invention relates to the technical field of thermochemical fuels, in particular to a fuel preparation device and application thereof.

Background

Based on thermochemical reduction of H in order to reduce the emission of carbon dioxide2O/CO2Preparation H2The technology of/CO fuels is receiving increasing social attention. Thermochemical reduction of H2O/CO2Preparation H2In the technical process of the/CO fuel, oxygen removal technology is particularly important. The conventional thermochemical reaction apparatus generally removes oxygen by a purge gas method or a vacuum pump method, however, the purge gas causes thermochemical reaction at high temperatureThe apparatus generates a large amount of heat loss (generally 5-30%), while the vacuum pump has an excessively low electrical efficiency (generally 5-40%) under a high vacuum (10-0.01 Pa absolute), and thus the energy conversion rate of the conventional thermochemical reaction apparatus is excessively low.

The present invention is directed to solving at least one of the problems of the prior art. Therefore, the invention provides a fuel preparation device which has the characteristic of high energy conversion rate.

The invention also provides an application of the fuel preparation device.

the working process of the invention mainly comprises the following steps: the oxide of the reactor is reduced at high temperature (300-3000 ℃) to release oxygen and become a reduction state for reducing H2O/CO2Generating H2a/CO fuel. Through the electrochemistry oxygen pump, the oxygen that the oxide produced in the ionization reactor accelerates oxide to the degree and the speed of reduction state conversion, specifically is: under the drive of electric energy, the cathode of the electrochemical oxygen pump ionizes oxygen to generate oxygen ions, the oxygen ions are transported to the anode, and electrons are lost to obtain oxygen.

Oxygen generated in the thermochemical reduction stage is quickly ionized by the electrochemical oxygen pump, and meanwhile, the power of the electrochemical oxygen pump can be adjusted in real time according to the rate of oxygen generated by oxides, namely, the oxygen can be efficiently removed in an energy-saving manner by adjusting the power input into the electrochemical oxygen pump, and the electrochemical oxygen pump is high in energy conversion rate and system efficiency.

Example 7

A fuel preparation apparatus, a cross-sectional view of a reactor part is shown in fig. 8, which is different from example 3 in that: one side of the oxygen pump cathode 11 of the electrochemical oxygen pump 1 departing from the electrolyte layer 12 is provided with a first current collector 141, and one side of the oxygen pump anode 13 of the electrochemical oxygen pump 1 departing from the electrolyte layer 12 is provided with a second current collector 142.

The working process mainly comprises the following steps:

step 1), light rays emitted by a heat supply device (a light-condensing photo-thermal device) irradiate a porous medium oxide layer through a glass plate, and the porous medium oxide layer absorbs light energy and converts the light energy into heat energy;

step 2) under the condition of high temperature, the oxide in the porous medium oxide layer is subjected to reduction reaction to release oxygen;

step 3), transferring the oxygen generated on the porous medium oxide layer to the cathode of an oxygen pump of the electrochemical oxygen pump, ionizing to generate oxygen ions, and oxidizing the oxygen ions at the anode of the electrochemical oxygen pump to form oxygen;

oxygen released from the porous medium oxide layer can be ionized in time, so that the reduction reaction rate is accelerated. When the reaction in the step 2) reaches the equilibrium, introducing H into the porous medium oxide layer2O/CO2Chemically reacting with the reduced porous dielectric oxide layer to form H2a/CO fuel.
