The efficiencies of chemical and electrochemical processes need to be increased in order to reduce their impact on the environment. Research in the field of catalysis has the potential to have a significant positive effect to address this need. Dr. Hill's group develops, characterizes and tests catalysts used in processes such as adsorption, hydrotreating, and gasification.

Sintered light expanded clay aggregates are described that are prepared by expanding and firing a claybased material, and where the finished aggregates have a diameter of up to about 32 mm, for use as filtration medium for purifying water, wherein carbonates of calcium and/or magnesium are added to the clay as flux material prior to expansion and firing.
At present, the Chinese lightweight aggregate plant or LECA production line tends to adopt the industrial rotary kiln. The cylindrical main kiln is placed on the idler pulley with the horizontal dip angle of 3degree.
Ceramsite production line is also called LECA production line and light aggregate ... Raw Materials:Clay, mudstone, slate, gangue, coal ash, shale, sludge and industrial ... Ceramsite sand is the alternative material of low and medium strength...

Expanded Clay or Lightweight Expanded Clay Aggregate (LECA) is a porous, chemically inert substance. It finds application in Hydroponics due to its high water retention qualities. LECA is produced by processing clay at a temperature of 2000° F inside a rotary kiln which renders air pockets in its physical structure.
Leca er eit akronym, henta frå det engelske Light Expanded Clay Aggregate. Materialet er lett og har god isolasjonsevne. A/S Norsk Leca vart skipa i 1954 av Bergensselskapet Rieber Søn, men vart i 1972 selt til sementprodusenten Norcem, som frå 1987 er del av Aker Norcem.
