Contributing activity / technique for the environment
Name of activity / technique:
Ammonium metatungstate as an intermediate in the production of catalysts
Environmental release category (ERC):
ERC6a: Use of intermediate
Contributing activity / technique for workersopen allclose all
Name of activity / technique:
Step 1: Raw material delivery and storage - The substance is delivered and stored as a solution.
Process category (PROC):
PROC 2: Chemical production or refinery in closed continuous process with occasional controlled exposure or processes with equivalent containment conditions
Name of activity / technique:
Step 2: Transfer of liquid raw material into production equipment - The liquid substance is pumped into production equipment
Process category (PROC):
PROC 8b: Transfer of substance or mixture (charging and discharging) at dedicated facilities
PROC 9: Transfer of substance or mixture into small containers (dedicated filling line, including weighing)
Name of activity / technique:
Step 3: Precipitation, Impregnation, Filtration, Drying and Mixing - The substance is used to prepare a supported catalyst system using classical catalyst preparation methods of precipitation and/or impregnation to disperse the substance on wet or dry carrier material. This is followed by filtration, drying, and mixing of the supported catalyst material.
