Plastic to Fuel | Pyrolysis Process - Chemical Engineering World

2020/10/8· The pyrolysis chaer is loaded with the grinded plastic along with a suitable alyst in order to promote specific types of chemical reactions. The temperature of the reaction can range from 200-900C based on the quality of the liquid oil desired further down the line as a product.

Chemical reactors

Most chemical reactions are faster at higher temperatures and heat exchangers are frequently used to provide the heat necessary to increase the temperature of the reaction. A common heat exchanger is the shell and tube type (Figures 12 and 13) where one part of the process flows through a tube and the other part around the shell.

Hydrogen Production: Thermochemical Water Splitting | …

2021/4/7· Hydrogen Production: Thermochemical Water Splitting. Thermochemical water splitting uses high temperatures—from concentrated solar power or from the waste heat of nuclear power reactions—and chemical reactions to produce hydrogen and oxygen from water. This is a long-term technology pathway, with potentially low or no greenhouse gas emissions.

Selective alytic Reduction - DieselNet

At low temperatures, the SCR reactions, Equation (1) to (5), dominate over the Pt alyst, so NOx conversion increases with increasing temperature as shown in Figure 4. At about 225-250°C, the oxidation of NH 3 to NOx and H 2 O, Equation (10), becomes dominant.
