苯是原油中提炼出来的化学合成物，1928年两个意大利医生检测到一名工人因长达五年的时间里暴露在苯环境中而患有癌症，他们发现苯可引发白血病。
Benzene, a chemical compound refined from crude oil, was found to cause leukemia in 1928 by two Italian doctors who detected the cancer in a worker exposed to benzene for five years.
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。
For instance, Craig Venter's Synthetic Genomics and other companies are trying to develop microbes that turn coal, tar shale and oil into methane.
但是LS9公司也计划制造一种被称作“生物原油”的东西，其中的脂肪酸将含有18 - 30个碳原子，而在合成过程的最好阶段将剔除氧原子，从而得到纯碳氢化合物。
In this case the fatty acids would have 18-30 carbon atoms, and the final stage of the synthetic pathway would clip off the oxygen atoms to create pure hydrocarbons.
