(Phys.org) —The advantages of sustainable, biodegradable, carbon-neutral and bioderived renewable polymers – that is, synthetic polymers based on biomolecules produced by living organisms – are reflected in the extent ...
(Phys.org) —Methane is the main component of natural gas, as well as a potent greenhouse gas whose levels in the atmosphere have been rising. In a new study, scientists have investigated a way to transform methane into ...
(Phys.org)—From petroleum refining to food processing, the vast majority of commercial chemical applications involve catalysts to control the rate of chemical reactions. Anything that can increase the efficiency of catalysts ...
Olefins are simple compounds of hydrogen and carbon but represent the building blocks of chemistry, and are vital for the synthesis of materials from polymers and plastics to petrochemicals. However, olefin production requires ...

(PhysOrg.com) -- This flow chart of the estimated US energy use in 2009, assembled by the Lawrence Livermore National Laboratory (LLNL), paints a pretty sobering picture of our energy situation. To begin with, it shows that ...
Petroleum (L. petroleum, from Greek: petra (rock) + Latin: oleum (oil)) or crude oil is a naturally occurring, flammable liquid consisting of a complex mixture of hydrocarbons of various molecular weights and other liquid organic compounds, that are found in geologic formations beneath the Earth's surface. Petroleum is recovered mostly through oil drilling. This latter stage comes after the studies of structural geology (at the reservoir scale), sedimentary basin analysis, reservoir characterization (mainly in terms of porosity and permeable structures). It is refined and separated, most easily by boiling point, into a large number of consumer products, from petrol and kerosene to asphalt and chemical reagents used to make plastics and pharmaceuticals. Petroleum is used in manufacturing a wide variety of materials.
