The growth trend and current application of heavy pyrolysis gasoline fraction was introduced generally.

The catalyst can reduce the content of sulfur in gasoline fraction without obvious decrease in its octane number and liquid yield.

该催化剂可以在脱除汽油馏分中硫的同时，不显著降低汽油的辛烷值和液收。

Through it, octane value of gasoline, cetane value of diesel oil, aromatics and sulphur contents in fraction oil can be calculated.

用此方法可以计算汽油的辛烷值、柴油的十六烷值、馏分油中芳烃和硫含量。

The latter's batteries can be charged off the electrical grid (which is almost entirely powered by non-oil fuels) and operate for upwards of twenty miles without using a drop of gasoline, and for a fraction of the cost of oil-based fuels.

Then of course, the automobile appeared on the scene, and the use case around gasoline displaced that around the heavier fraction (kerosene) in importance.

First, while production had grown substantially over the years, it still amounted to a tiny fraction of U.S. gasoline demand.
