VEBA combi-cracking processing

Veba Combi Cracking process (Germany, operational until 2000)... 

CANMET hydrocracking and VEBA Combi-Cracking processes are presently demonstrated. Both processes use the same concept of liquid-phase hydrogenation of the feed and of gas phase... 

The Veba Combi-Cracking process is suitable for converting residue oil and plastics waste.

Veba-Combi Cracking (VCC) process a thermal hydrocracking/hydrogenation process for converting heavy feedstocks. 

This section deals with the economic evaluation of the conversion of mixed plastics waste (MPW) into synthetic crude (syncrude) oil and coprocessing of MWP with vacuum residue into syncrude. In their feasibility study, Ali and co-workers considered the process technology developed by Veba Oel AG of Germany the Veba Combi-Cracking (VCC) option for the processing of MPW [31], The process data and economic data were taken mainly from Dijkema and Stougie [32] and Huffman and Shah [33] for this study. All the cost data were translated to represent the economic analysis for Saudi Arabian conditions. 

As well as direct incineration of plastics waste, imder clean and efficient conditions, there has been some research into conversion into fuel oil, by chemical methods. The Veba Combi-Cracking (VCC) process produces synthetic crude oil under liquid phase hydration. In trials, 100 tonnes of mixed and contaminated plastics waste from normal domestic sources was hydrated to high quality oil, similar to that used as a source for diesel fuel. With metal-free granular material, costs were estimated at about DM 500/tonne. The process has also been used with polyurethane waste, producing oil that can be mixed with new oil (but costing over twice). 

Veba-Combi Cracking Also called VCC. A Bergius-Pier high-pressure thermal hydrotreating process. The catalyst is usually a promoted iron oxide, operated in a slurry, but an added catalyst may not be necessary.
