Stepping up the attack against acid rain and smog, Energy and Environment Division researchers have developed a new technology to help eliminate sulfur dioxide air pollution from power plants, incinerators, chemical plants, and smelters.
Part of a multistage treatment system, the new process treats concentrated sulfur dioxide, converting more than 95 percent of it to a valuable commodity--elemental sulfur, a chemical feedstock that can be sold.
A number of effective technologies have been developed to treat fossil fuel emissions before venting them into the atmosphere. However, due to the cost, most of the world's power plants do not significantly treat exhaust gases. Likewise, utilities often elect not to burn abundant fuels such as coal, which have a relatively high sulfur content, because of the expense of removing sulfur dioxide.
The E & E Division team, which includes Shih-Ger Chang and visiting professors Yun Jin and Qiquan Yu from Bejing University, say the primary advantages of their new technology are its simplicity and affordability.
The process relies on the team's invention, a new catalyst for which a patent is pending.
Says Chang, "The catalyst consists of an inexpensive mixture of iron-based metal oxides supported on alumina. We have tested it in the laboratory over a lifetime of 1,080 hours and the catalytic activity is very stable. The yield of sulfur recovery over the course of our lifetime test was 96.5 percent."
Dealing with sulfur has frustrated the emergence of one promising clean coal technology, the Integrated Gasification Combined-Cycle (IGCC) method. The method can convert 42 percent of the energy potential in coal into electricity, a seven-percent improvement over the technologies now in common use.
IGCC combines coal, water, and heat to produce a synthetic gas that consists of carbon monoxide, hydrogen, and hydrogen sulfide. However, before this hot gas can be burned to produce electricity, the hydrogen sulfide must be treated.
Researchers have been looking for a way to remove the hydrogen sulfide from the initial synthetic hot gas mix. One technique under development sprays the hot gas with metal salts, which ultimately results in the production of reusable metal salts and concentrated sulfur dioxide
In the new LBL process, synthesis gas and concentrated sulfur dioxide are fed into a catalytic chamber, which in a single step, reduces more than 95 percent of the sulfur dioxide to elemental sulfur. This makes the IGCC method more efficient and more affordable.
A Reduction In Force (RIF) status was announced last week for all LBL Operations and Administration divisions. Effective August 8, the RIF status means that all hiring activity, promotions, and reclassifications in those divisions are temporarily frozen.
The Laboratory may have to lay off between 35 and 50 employees from the affected divisions. Volunteers will be considered in lieu of others and those interested in taking a voluntary layoff should contact their divisional offices as soon as possible. The RIF status is the result of reductions in LBL's funding base for FY95.
"The income to the Laboratory is not adequate to keep up with inflation," said Klaus Berkner, Associate Laboratory Director for Operations. "As a consequence, we have more people than we have money to support."
The areas impacted include the Accelerator and Fusion Research Division, the Engineering Division, the Information and Computing Sciences Division, the Environment, Health and Safety Division, the Facilities Department, and the Administration Division.
Employees who are to be laid off will be notified by mid-September.
On a two-day trip to Africa this spring, Dycus and his wife, Marva, brought back the five new additions to join their five natural children. All twelve recently posed for their first portrait.
"People said that it would take awhile for the kids to really fit into the family," he says. "But within a week, everyone felt like brothers and sisters. There's been a lot of love."
Dycus admits that five more growing bodies has put a strain on the budget. "The main thing has just been buying more food," he says. Each week the family goes through six gallons of milk, five large boxes of cereal, ten loaves of bread and "lots of macaroni and cheese."
Transportation has been another concern, as simple family outings have taken on problems commonly associated with mass transit. Dycus says he hopes to buy a 15-passenger van, with proper seats and seatbelts for everyone.
He says the children's education is going smoothly. (They are being schooled at home.) He says the kids, who range in age from two to ten, love listening to stories in English and are learning the new language at a furious clip. "Its been incredible how fast they've picked up the syntax in four months," he says. Dycus says he would like to thank the LBL employees who have contributed money and clothing to help the children settle into their new home.
PHOTO CAPTION -- The Dycus family are (top row, left to right) Michael, Fred, Bayley, (row 2) Nina, Marva, Delia, (row 3) Amy, Fred Jr., Phoebe, (row 4) Titus, America, and (at bottom) Liberty. The last five are the adopted children, listed with their new American names.
A resident of El Sobrante, Young worked at the Lab from July 1957 until his retirement in October 1986. During most of that time, he worked in the Electronics Research Group in support of the Beam Cooling Group. He was known for his excellent work in fabricating complex electronic equipment, such as Owen Chamberlain's Proton Spin Resonance System 1260, spark gap trigger amplifiers for High Energy Physics groups, NMR systems for the Biodynamics Group and the Electron Beam Cooling Amplifier System used at Fermi Lab.
Young was known among local radio amateurs (Hams) for having the most powerful transmitter on this side of the Bay. His antenna, which was located at the top of the hill on Skyline Drive in El Sobrante, had a 360-degree sweeping "view "of the Bay Area and far beyond.
Services were held last month at Westbrae Bible Church in Berkeley; he was buried at Rolling Hills Memorial Park in Richmond. Young is survived by one brother and three sisters-in-law.

Q: Do researchers at LBL ever get to patent their own inventions?
A: Yes, under certain circumstances.
The patent process at LBL starts with an inventor filling out an invention disclosure form, which is sent to the Patent Department. Almost every week members from the Patent Department and the Technology Transfer Department meet to discuss the latest inventions and to decide whether LBL should obtain patents for them. If LBL (UC Regents) elects to obtaIn title, a letter stating this is sent to the inventor(s) and LBL starts preparing an application.
If LBL does not elect to patent the invention, the U.S. Department of Energy takes title. If inventors then wish to patent their inventions themselves, they must petition DOE for the right to do so.
