Description

一种炭载过渡金属碳化物催化剂在肼分解反应中的应用 Application of a carbon-supported transition metal carbide catalyst in the decomposition of hydrazine

技术领域 technical field

本发明涉及用于肼分解反应的催化剂,具体的说是一种以炭材料为载体,以单组元或双组元过渡金属碳化物为活性组分的催化剂在肼分解反应中的应用。The invention relates to a catalyst for hydrazine decomposition reaction, in particular to the application of a catalyst with a carbon material as a carrier and a single-unit or two-unit transition metal carbide as an active component in the hydrazine decomposition reaction.

背景技术 Background technique

肼在常温下是一种稳定的液态物质,250℃左右可发生热分解反应。在催化剂的作用下可在较低温度下发生分解反应,生成高温高压的氮气、氢气和氨气混合气体。长期以来,肼作为液体燃料被广泛的应用于航天飞行器的姿态控制系统,飞机的应急动力系统,以及探空气球、沉船或潜艇的浮力装置等。Hydrazine is a stable liquid substance at normal temperature, and thermal decomposition reaction can occur at about 250°C. Under the action of the catalyst, the decomposition reaction can occur at a lower temperature to generate a high-temperature and high-pressure mixed gas of nitrogen, hydrogen and ammonia. For a long time, as a liquid fuel, hydrazine has been widely used in the attitude control system of aerospace vehicles, the emergency power system of aircraft, and the buoyancy devices of sounding balloons, sunken ships or submarines, etc.

目前使用最广泛的肼分解催化剂是美国Shell公司研制的20-40%Ir/γ-Al2O3催化剂[U.S.Pat.4,124,538]。但是,催化剂的活性组分铱是稀有的贵金属,是一种高级战略物资,价格昂贵;而且催化剂的载体是经过特殊加工的氧化铝,所以这种催化剂的成本很高。因此开发新型、低成本的肼分解催化剂成为各国科研工作者的研究重点。Currently the most widely used hydrazine decomposition catalyst is the 20-40% Ir/γ-Al 2 O 3 catalyst developed by the US Shell Company [USPat.4,124,538]. However, the active component of the catalyst, iridium, is a rare precious metal, a high-grade strategic material, and is expensive; and the carrier of the catalyst is specially processed alumina, so the cost of this catalyst is very high. Therefore, the development of new and low-cost hydrazine decomposition catalysts has become the research focus of scientific researchers in various countries.

[PCT Int.Appl.WO 9,633,803]报道了纯相的过渡金属碳化物用于肼分解反应的结果,表明此类催化剂具有与贵金属铱催化剂类似的肼分解活性。陈小伟等[CN 01101118.1]报道了以γ-Al2O3为载体的负载型Mo2C催化剂的肼分解活性。发动机的实验结果表明,这种催化剂在肼分解反应中有很好的催化活性。[PCT Int.Appl.WO 9,633,803] reported the results of pure-phase transition metal carbides used in hydrazinolysis reaction, indicating that such catalysts have similar hydrazinolysis activity to noble metal iridium catalysts. Chen Xiaowei et al. [CN 01101118.1] reported the hydrazinolysis activity of supported Mo 2 C catalysts supported by γ-Al 2 O 3 . The experimental results of the engine show that this catalyst has good catalytic activity in the hydrazine decomposition reaction.

各种炭材料作为载体被广泛的应用于各类液相反应和涉氢反应中,但是将其作为载体在肼分解反应中的应用还没有专利和文献报道。Various carbon materials are widely used as carriers in various liquid phase reactions and hydrogen-related reactions, but there are no patents or literature reports on their use as carriers in hydrazine decomposition reactions.

Different carbon-supported transition metal carbide catalysts can be prepared.

本发明的催化剂可用于各类肼分解反应,从而可进一步用于航天飞行器的姿态控制系统、飞机的应急动力系统、以及探空气球、沉船或潜艇的浮力装置的肼分解发动机中。The catalyst of the present invention can be used in various hydrazine decomposition reactions, and thus can be further used in the attitude control system of aerospace vehicles, the emergency power system of aircraft, and the hydrazine decomposition engines of buoyancy devices of sounding balloons, sunken ships or submarines.

本发明的优点为:The advantages of the present invention are:

1.该催化剂制备工艺简单,可批量生产。由于催化剂的活性组分和载体分别是廉价的过渡金属碳化合物为和廉价的炭材料,因此大大降低了制备成本。1. The preparation process of the catalyst is simple and can be produced in batches.

催化剂的评价Catalyst evaluation

本发明的催化剂评价是在1N发动机上进行的。实验采用气体挤推方式供应肼燃料,将催化剂床层预热至实验温度后,通过电磁阀控制肼分解反应进程。燃压Pc和催化剂床层温度Tc使用相应传感器测定。The catalyst evaluations of the present invention were carried out on a 1N engine. In the experiment, hydrazine fuel was supplied by means of gas extrusion, and after the catalyst bed was preheated to the experimental temperature, the hydrazine decomposition reaction process was controlled by a solenoid valve. The fuel pressure P c and the catalyst bed temperature T c are measured using corresponding sensors.

(一)不同催化剂肼分解活性比较,肼分解活性评价结果见表1。(1) Comparison of hydrazine decomposition activity of different catalysts, the evaluation results of hydrazine decomposition activity are shown in Table 1.

从表1中可以看出,以活性炭为载体制备的金属铱催化剂、单组元或双组元过渡金属碳化物催化剂,在催化肼分解过程中产生的床温和燃压均高于Ir/γ-Al2O3催化剂,说明以活性炭为载体的催化剂具有更高的肼分解效率。t90是体现发动机整体性能的一个重要指标,一般来说,t90小于1000ms,就基本达到实际应用的要求。表1中结果显示,Ir/γ-Al2O3催化剂的t90为410ms,单组元或双组元过渡金属碳化物催化剂的t90在400ms和600ms之间,与Ir/γ-Al2O3催化剂相当,说明其有很好的应用前景。WNiCx/AC-h和WCoCx/AC-h催化剂的t90分别为405ms和415ms,均小于W2C/AC-h催化剂的t90,说明第二组分的加入提高了催化剂的启动加速性。It can be seen from Table 1 that the bed temperature and combustion pressure generated in the catalytic hydrazine decomposition process of metal iridium catalysts, single-component or two-component transition metal carbide catalysts prepared with activated carbon as the carrier are higher than those of Ir/γ- Al 2 O 3 catalyst, indicating that the catalyst supported by activated carbon has higher hydrazine decomposition efficiency. The t 90 is an important index reflecting the overall performance of the engine. Generally speaking, if the t 90 is less than 1000ms, it basically meets the requirements of practical applications. The results in Table 1 show that the t 90 of the Ir/γ-Al 2 O 3 catalyst is 410ms, the t 90 of the single-component or dual-component transition metal carbide catalyst is between 400ms and 600ms, and the t 90 of the Ir/γ-Al 2 O 3 catalyst is equivalent, indicating that it has a good application prospect. The t 90 of the WNiC x /AC-h and WCoC x /AC-h catalysts are 405ms and 415ms, respectively, both of which are smaller than the t 90 of the W 2 C/AC-h catalyst, indicating that the addition of the second component improves the start-up acceleration of the catalyst sex.

(二)将使用不同方法制备的两种活性炭担载型碳化钨催化剂的最低启动温度进行了比较,比较结果见表2。从表2中可以看出,33.3wt%W2C/AC-h催化剂的最低启动温度明显低于33.3wt%WCx催化剂,说明采用氢气程序升温反应方法制备的W2C/AC-h催化剂具有更好的肼分解启动活性。(2) The minimum start-up temperatures of two activated carbon-supported tungsten carbide catalysts prepared by different methods were compared, and the comparison results are shown in Table 2. It can be seen from Table 2 that the minimum start-up temperature of the 33.3wt% W 2 C/AC-h catalyst is significantly lower than that of the 33.3wt% WC x catalyst, indicating that the W 2 C/AC-h catalyst prepared by the hydrogen temperature-programmed reaction method It has better hydrazinolysis initiation activity.

(三)将33.3wt%W2C/AC-h催化剂与33.3wt% Ir/AC催化剂的肼分解稳定性进行了比较,比较结果见表3。(3) The hydrazine decomposition stability of the 33.3wt% W 2 C/AC-h catalyst and the 33.3wt% Ir/AC catalyst were compared, and the comparison results are shown in Table 3.

从表3可以看出,33.3wt% W2C/AC-h催化剂经历了10次30秒稳态实验后,催化剂质量损失很少,而33.3wt% Ir/AC催化剂仅经历2次30秒稳态实验后,催化剂质量损失达到60%以上,说明活性炭担载的碳化钨催化剂具有更好的肼分解稳定性。It can be seen from Table 3 that the 33.3wt% W 2 C/AC-h catalyst underwent 10 times of 30-second steady-state experiments, and the mass loss of the catalyst was very little, while the 33.3wt% Ir/AC catalyst only experienced 2 times of 30-second steady-state experiments. After the state test, the mass loss of the catalyst reached more than 60%, indicating that the activated carbon-supported tungsten carbide catalyst has better hydrazine decomposition stability.
