"Chemical feedstocks" refers to raw materials or substances that are used to produce various chemicals or products through chemical processes. It is like the ingredients used to make different chemical products. Full definition
We might still need it for chemical feedstocks for non-fuel products and it might still be more convenient for those nations who have plenty of fossil fuels but a barrel of oil won't be saleable for over $ 15 because biofuel will be cheaper. (wattsupwiththat.com)
Domestic industries can make it from a range of chemical feedstocks and energy sources (for instance, from renewable, nuclear and fossil - fuel sources), and the nontoxic gas could serve as a virtually pollution - free energy carrier for machines of many kinds. (scientificamerican.com)
Here we show that pyrolysis oils can be converted into industrial commodity chemical feedstocks using an integrated catalytic approach that combines hydroprocessing with zeolite catalysis. (science.sciencemag.org)
