Description
Technical Field
[0001] The present application relates to the field of hydrogen production technology, and in particular to a photothermal-synergistic formic acid hydrogen production system. Background Art
[0002] With the rapid development of the global economy, traditional fossil energy has caused serious environmental pollution problems. It is urgent to change the dependence on the traditional fossil energy system and establish a green energy structure. The shift of energy structure to high energy density "zero emission" energy carrier - hydrogen has become a hot topic in current research.
[0003] At present, the widespread application of hydrogen energy faces an important bottleneck problem, namely the difficulty in safe and efficient storage and transportation of hydrogen. The main storage and transportation process of hydrogen is to transport gaseous or liquid hydrogen through special high-pressure storage tanks or pipelines. Although the technology is relatively mature, it requires specific low temperature or high pressure conditions, which not only increases energy consumption and costs, but also poses considerable challenges to safety.
[0004] Formic acid (HCOOH) is the simplest hydrogen-containing monobasic organic carboxylic acid. The Gibbs free energy of the formic acid decomposition reaction to produce hydrogen at room temperature is negative, that is, thermodynamically favorable. Compared with other hydrogen carriers (such as methanol, ammonia, etc.), which all rely on high temperature, high pressure and catalyst-catalyzed reaction conditions to decompose and produce hydrogen, formic acid can be efficiently decomposed into hydrogen and carbon dioxide at room temperature and pressure under the action of a catalyst. Therefore, formic acid hydrogen production is one of the most feasible hydrogen production methods at this stage. However, traditional technology uses PSA or palladium membrane purification to purify hydrogen, but high energy consumption and low yield are the biggest problems. The basic hydrogen comprehensive yield is about 80%, and the energy consumption of pressurized heating is high. At the same time, it faces a series of problems such as tail gas recovery; in the prior art, when formic acid is used to produce hydrogen, due to the limitation of the catalyst arrangement, the light cannot be irradiated to all parts of the catalyst, resulting in insufficient illumination, affecting the catalytic reaction, and making the hydrogen production efficiency low.
