微波协同热解条件对生物炭除冰性能的影响
Influence of microwave synergistic pyrolysis conditions on the deicing performance of biochar
摘要
Abstract
Road icing is a threat to the national traffic safety and economic development.Microwave heating is a promising deicing technology,which has advantages of environmental protection and high efficiency.However,it is still limited by the performance of absorbing agents.Nowadays carbon-based materials have attracted more attention to act as absorbers with good performance,but there are problems to limit their wide utilization,such as high cost and long preparation time.The article takes peanut straw particles to prepare biochar as an absorbent in laboratory environment,which is based on our microwave-induced synergistic pyrolysis process and the orthogonal experiment with three factors-four levels.The effects of important preparation parameters,such as conventional pre-pyrolysis temperature,pre-pyrolysis time and retention time of microwave intensive pyrolysis,on the deicing performance of biochar are analyzed.The results show that the conventional pre-pyrolysis temperature is a vital factor to affect the deicing performance of biochar.When synergistic pyrolysis conditions is optimum(i.e.the conventional pre-pyrolysis temperature reach up to about 700℃,the pre-pyrolysis retention time is 6min and microwave pyrolysis with 800W and 2min),the obtained biochar has the best deicing performance due to its temperature rising ability under microwave irradiation.And the optimum biochar is irradiated with microwave power of 800W for about 20s,the deicing time is about 30s and the de icing efficiency can be improved up to 97％compared with that without biochar.The above conclusions have significance for guiding the development of new road materials or additives.关键词
