shale tar

After removing minerals of asphalt shale by HCl/ HF mixing acids, the conversion ratio increased and tar yield reached 14.4%.

沥青页岩经HCl/HF脱除矿物质后，与神府煤共热解时的转化率增加，焦油产率达到14.4%。

Europe is of course unlikely to get the huge energy windfall from which the US is starting to benefit the fruits of shale gas, tight oil and the potential future supply of tar sand oil from Canada.

当然，欧洲不太可能获得巨大的能源“横财”，而美国正开始受益于页岩气、致密油，未来还有望受益于来自加拿大油砂的石油。

but there is also oil sand and tar sand and oil shale and they may be called by some new euphemism like shale tar

但我们还有油砂焦油砂油页岩也许以后还会有人起新的名字例如页岩焦油
