Chemical Reactor

How kinetics ruins control, leads to undesirable outcomes, and makes chemical production look like a casino.

Researchers from MIT and elsewhere have demonstrated a new way to produce a critical component of aviation fuel from lignin, a plant material that's generally discarded as waste during biomass processing. If samples of the new product pass a final test for jet-fuel certification, the result could be aviation fuel that's made entirely from sustainable sources.

Lanthanum trihydride, a compound of lanthanum and hydrogen, when lightly doped with oxygen shows potential as an efficient hydrogen carrier, according to a new study. Hydride ion (H--) conductors are expected to be used in chemical reactors and energy storage systems. However, the low H-- conductivity at room temperature introduces certain technical limitations. These limitations may now be overcome with this…

MIT engineers developed a way to make clean ammonia, without fossil-fuel-powered chemical plants, using the Earth as a geochemical reactor, producing ammonia underground.

The tricarbon molecule (C3) is likely produced in the upper atmosphere of Titan by the reaction of abundant acetylene with atomic carbon.

Young Suk Jo cofounded Amogy to decarbonize the transportation sector by engineering ways for trucks and ships to run on a common fertilizer ingredient.

University of Alabama researchers are exploring how to create jet fuel from plants as a renewable fuel source that will reduce greenhouse gas emissions.

Global warming has been attributed to the sharp increase in heat-trapping greenhouse gas emissions, in particular CO2 emissions. Carbon capture technology, such as using adsorbents to capture and store CO2 from ambient air, is a promising solution to mitigate emissions.

Ammonia, used in fertilizer, is essential to our lives. Addis Energy is trying to make the chemical underground.

Adipic acid, a fundamental component in the manufacture of chemical fibers, nylon 66, engineering plastics, and various pharmaceutical, food, and chemical products, is commonly synthesized through a green process involving the oxidation of cyclohexene with hydrogen peroxide (H2O2) catalyzed by sodium tungstate (Na2WO4).

A fabrication process can produce self-heating microfluidic devices in one step using a multimaterial 3D printer. These devices, which can be made rapidly and cheaply in large numbers, could help clinicians in remote parts of the world detect diseases without expensive lab equipment.

A new type of catalyst breaks down polyolefin plastics into new, useful products. This project is part of a new strategy to reduce the amount of plastic waste and its impact on our environment, as well as recover value that is lost when plastics are thrown away. The catalyst was developed by a team from the Institute for Cooperative Upcycling of Plastic (iCOUP), a U.S. Department of Energy, Energy Frontier Research…

MIT researchers have designed a system that uses flames to produce materials critical to lithium-ion batteries. Their combustion-based method promises to be simpler, much quicker, and far less energy-intensive than the conventional method now used to manufacture cathode materials.
