For instance, Craig Venter's Synthetic Genomics and other companies are trying to develop microbes that turn coal, tar shale and oil into methane.───例如，克雷格·文特尔(Craig Venter)的合成基因学说，以及其他一些公司正在试图开发把碳、页岩焦油和原油变为甲烷的微生物。
Pitch and pitch coke, obtained from coal tar or from other mineral tars.───从煤焦油或其他矿物焦油所得的沥青及沥青焦。
According to the demands of the market, high quality reconciliation oil made from concoction of coal-tar oil and heavy-oil was also studied.───根据市场的需求，本文还研究了由煤焦油与重油调配成品质较高的合成燃料油。
Therefore it was decided to treat the surface using a coal tar mixture that would penetrate the pavement and bind the pavement together.───因此决定使用这种具有渗透性和能重新粘结道路的煤焦油混合剂来处理整个表面。
