在高压反应釜中进行了神木烟煤与CO2吸收剂CaO混合物的蒸汽气化反应,实现了在一个反应器内直接制甲烷的工艺。典型工况下气态产物中甲烷含量(体积分数)占62.28%,氢气占25.05%,一氧化碳和二氧化碳含量均低于0.1%,验证了煤直接制甲烷反应的可行性。实验研究了温度,压力,钙碳摩尔比[Ca]/[C],以及水碳摩尔比[H2O]/[C]的变化对反应产物及碳转化率的影响。结果表明降低反应温度和提高反应压力有利于甲烷的产生,[Ca]/[C]=0.5和[H2O]/[C]=1时具有良好的制甲烷效果。 相似文献

This article has introduced the origin and speciality of fast-transient signal, and told the meaning of researching on fast-transient signal. The main troubles of sampling on fast-transient signal is its `fast' and `transient', and the experiment's bad condition also troubles the transmission of information. To solve those troubles we put forward a technology called `digital Forward-sampling', and designs a sampling system for the fast-transient signal with this technology. The sampling rate of this system is 1.2 GSPS; it could get the whole pulse of fast-transient signal through the digital Forward-sampling technology; this system also could transmit the result to the analyzing equipment kilometers away immediately, before the data was destroyed by the electromagnetic and 相似文献

A digital transmission system with 900 MHz bandwidth and over 40 dB linear dynamic range for high intensity pulsed radial detection is designed. The transient signals (with a subnanoseconds rising edge) from the detectors can be transmitted to diagnosing systems kilometers away with high fidelity. It can adapt to interference and a hostile detecting environment by using the intelligent functions of this system. The feasibility and reliability of this system is verified by system evaluation tests. 相似文献
