Normally, silicon carbide is produced by heating sand (which is made of quartz, or silicon dioxide) in an electric furnace with carbon made from oil or coal.
通常，硅碳化合物通常由加热的沙子(通常由石英构成，或称二氧化硅)和石油或煤炭中提取的碳放在电气炉内反应而得到。
By 2012, if it stays on track, Mexico will have reduced its carbon dioxide emissions by 50 million tons, equal to the carbon produced by 45 days of domestic oil production.
到2012年，如果这一切进展顺利，墨西哥将会减少5000万吨碳排放，相当于国内石油生产45天内所产生的二氧化碳。
If production is ramped up, the captured carbon could be used for enhanced oil recovery or, in the longer term, possibly pumped into the deep ocean.
如果产量上升，捕获的碳还可以用于“提高采收率法采油(enhancedoil recovery)”，或者为长远计而储存到深海中去。
When you burn a hydrocarbon fuel such as oil, its hydrogen and carbon atoms combine with oxygen from the atmosphere to create water and carbon dioxide.
当你在烧氢类燃料(如石油)时，燃料中的氢原子和碳原子与空气中的氧结合反应，生成了二氧化碳和水。
And, of course, we’ll also see how well the planet can handle the extra carbon emissions and the intensifying competition for oil.
但是，当然，我们也要面对这个地球要怎么解决碳排放的问题，怎么缓解石油竞争的紧张局势的问题。
Some oil firms do this already to carbon dioxide that forms part of raw natural gas.
许多石油公司已经这样做了，将二氧化碳变成天然气的一部分。
