WebFeb 11, 2024 · This suggests the CSTR will likely reduce OCM preheating requirements. The catalytic activation of CH4 by limited amounts of O2 produces a mixture of synthesis gas (CO, H2) and light hydrocarbons (C2Hx), the relative amounts of each depending on catalyst type and process conditions. Using an elementary reaction mechanism for the … WebYou have decided to design a CSTR with recycle to degrade TCE (trichloroethylene) cometabolically by aerobic phenol-utilizing bacteria. To do this, you will feed phenol (C 6 H 5 OH; as a C source) and oxygen, along with required nutrients, to the reactor in order to grow a population of bacteria that can fortuitously degrade TCE. The problem is to first …
