为解决冲击地压常规解危措施中的难题,研发了冲击地压防治新技术,即液态CO2致裂。系统介绍了液态CO2致裂技术的工作原理,在实验室中通过自主研发设备进行压力转化率测试,测试了不同孔壁和泄能头间距与爆破压力的关系,根据实验室研究成果在现场进行了工业性试验。研究实践表明,液态CO2致裂无明火、可反复使用,是一种新型安全高效的防冲手段。孔壁和泄能头间距越小,孔壁所受压力越大;间距为10~21 ...
草酸的稳定性及CO2包裹体压力计实验研究
草酸 二氧化碳 拉曼光谱 压力标定
2015/12/3
应用金刚石压腔(diamond-anvil cell)实验技术,对草酸的稳定性进行了研究。草酸在高压低温条件下可以稳定存在,而在低压高温条件下将分解为CO2、H2O等气体。当成矿流体遇到破裂带或裂隙而发生减压沸腾时,可以使成矿流体中的有机络合物迅速发生分解产生大量CO2,从而造成金属元素在有利的空间沉淀、富集成矿。同时,实验研究了高温高压条件下CO2的物理化学性质,得到了CO2包裹体压力计的测定方...

The movement of carbon, in its many forms, between the atmosphere, oceans, biosphere, and geosphere is described by the carbon cycle (Figure 1). This cycle consists of several storage pools of carbon ...
Oil, coal, and other fossil fuels are called hydrocarbons because they are made of both carbon and hydrogen. Millions of years ago, plants took hydrogen out of water and combined it with carbon to cre...
O2/CO2气氛下氮反应机理的研究
氮氧化物 O2/CO2 NO
2012/3/16
选取CH4、O2、CO2、Ar、NO、NH3等气体,作为混合气和煤粉一起送入一维沉降炉内,以模拟O2CO2气氛下煤中燃料氮、循环NO以及二者的相互作用对NO排放的影响.结果显示,在还原性气氛下NH3、HCN、CH4、CO与循环NO间的反应是NO排放下降的主要因素,且煤焦与NO的异相反应、吸附反应对NO的降解效果要明显高于氧化性气氛,同时,CO2体积分数的增加使得燃料中氮的氧化率升高,循环NO的降解...
