-recycle and reuse - innovations
uses hydrogen gas and a catalyst to produce gasoline and diesel fuel with significantly lower levels of sulfur and lead
hydrotreatment
To capture and neutralize air pollutants
green manufacturing
cheapest, most plentiful yet most polluting
coal
method to generate electricity and produce fuels from coal with significantly less environmental impact
coal gasification
potable drinking water
purify
treating water
▪ Vacuum or pressure filtration
▪ Centrifugation
▪ Membrane-based separation
▪ Distillation
▪ Carbon-based and zeolite-based adsorption
▪ Advanced oxidation treatments
Blending recycled paper and water produce a
pulp slurry
considered by many as the father of activated carbon treatment of water and wastewater
Walter Weber Jr.
He is renowned for his 1972 classic book, Physicochemical Processes for Water Quality Control.
Walter Weber Jr.
He is Professor of Environmental and Ecological Sciences and Engineering in the Department of Chemical of Engineering at the University of Michigan, a member of the National Academy of Engineers
Walter Weber Jr.
2007 recipient of the Lawrence K. Cecil Award for excellence in environmental applications of chemical engineering
Walter Weber Jr.
from New Jersey Institute of Technology that works on finding ways to create extraordinarily tiny membrane pores. Today
Kam Sirkar
he and his colleagues are pursuing the development of nanoporous membranes, whose nanometer-sized pores provide an opportunity for unimaginably exacting separations
Kam Sirkar
at the University of North Carolina (Chapel Hill) pioneered to create a family of nontoxic surfactants based on the enhanced solvency of liquid carbon dioxide and developed systems to use these safer solvents help the chemical, automotive, aerospace, electronics, petroleum
-refining, pharmaceutical, pulp-and-paper and other sectors to reduce or eliminate the use of hazardous organic and halogenated solvents as cleaning agents, process aids and dispersants
Joseph Desimone
In 1997, he was awarded the Presidential Green Chemistry Challenge Award from the U.S. Environmental Protection Agency.
Joseph Desimone
Professor of Chemical Engineering at the University of Michigan, received the Clarence (Larry) G. Gerhold Award from AIChE’s Separations Division in 1997 for outstanding contributions in research, development and application of chemical separations technologies for the removal of harmful pollutants before producing harmful emissions.
Ralph Yang
Among his achievements are groundbreaking work on the development of desulfurization sorbents via pi-complexation that selectively adsorb sulfur from diesel fuels and zeolites that remove nitrogen from transportation fuels.
Ralph Yang
It maximized the amount of catalyst-coated surface area to which the engine exhaust may be exposed
Catalytic Inverters
It minimized the amount of expensive precious-metal catalyst required
Catalytic Inverters
advanced petroleum-refining techniques
Cleaner-burning Fuels
3 approaches of water treatment
Centrifugation
Distillation
Pressure Filtration
(True or False) Almost one-thirds of the aluminum cans in the United States are recycled, and 85% to 90% of the aluminum in cars is recycled
False (two-thirds)
