Batelle process

The Batelle process represents the first attempt to recover metals from spent hydro-processing catalysts using electrochemical dissolution in a membrane reactor (Silva, Bray, Matson, 1993). In this process, the spent catalyst is added to a solution containing small (catalytic) amounts of elements that form kinetically active, strongly oxidizing ions such as or Ag +. All these efforts contribute to the developments and design of the ECDS process as well as the metal recovery. 

High temperature pyrolysis or back to monomers processes produce a mixture of monomers such as ethene and propene but can also be used to produce aromatic compounds like benzene and toluene. The products can be used after separation and purification to produce new polymers. Developed since the 1970 s three different processes have been established the Kaminsky or Hamburg University process, the Batelle process and the Union Carbide process [5,8]. 

Among other pyrolytic processes, the Batelle process employs a Circulating Fluidized Bed as main reactor. Pilot plant scale experiments have been conducted with PE, PS, PVC and various polymer mixtures with nitrogen or steam as fluidization media. 

Crops, food, and feed. The first recommended method is based on the Dutch Multiresidue Method 2 for A-methylcarbamates, which was originally developed by de Kok et The method has recently been validated by DuPont Crop Protection and Batelle, Geneva Research Centres, for the analysis of methomyl and oxamyl in dry, high-water, high-fat, and high-acid content crops and in various grape processed products. The limit of detection for each analyte is 0.003-0.005 mg kg . ... 

Later some features of the SERATRA Model, developed by Batelle Northwest Laboratories (5 ) were added. This model was designed to simulate the behavior of sediment and associated constituents in streams. It includes processes such as hydrolysis and photolysis and is thus suitable for modeling toxic substances such as pesticides.
