gas yield

Gas and liquid products were mainly isolated in 100-400 ℃ with microwave heating Cellulose and lignin had higher gas yield rate in the pyrolysis process, the maximum liquid yield rate was reached at about 200 ℃.

微波热解中气体和液体主要在100-400℃之间生成，纤维素和木质素热解的产气速率较高，200℃左右时液体产出速率达到最大值。

Secondly, experiment of biomass pyrolysis in tube furnace is carried out to study the effect of porous bed material on gas yield, tar yield, tar yield and content of hydrogen.

其次，在管式气氛炉中研究床料对生物质热解产气量、焦油产量以及热解产富氢燃气的影响。

The gas yield increased with the increase of temperature. The low heating value ( LHV) of pyrolysis gas would decrease because of the decomposition of CH4 and C2H4 at high temperatures.

升高热解温度有利于提高热解气的产量，但是高温会使CH4和C2H4裂解，从而造成热解气热值下降。

On-site Measurement of Landfill Gas Yield and Verification of IPCC Model

生活垃圾填埋气体产量的现场测试及IPCC推荐模型的校验

Otherwise, the cracked gas yield and propylene selectivity will go up.

相反，则裂化气产率和丙烯选择性提高。

The experimental results showed that bimolecular reaction pattern was dominant over catalyst A, which resulted in lower dry gas yield and lower olefin content in cracked naphtha.

试验结果表明，双分子裂化反应历程在催化剂A上发生机率较大，表现为较低的干气产率，较低的汽油烯烃含量；

In global unconventional gas-bearing systems, basin-centered gas system ( BCGS) may be one of the most prolific accumulations. In America, 15% of annual natural gas yield comes from Basin Centered Gas Accumulatiom ( BCGA).

在全世界的非常规含气系统中，盆地中心气系统（BCGS）可能是经济价值较大的一种，美国每年的天然气总产量有15%来自盆地中心气系统。
