  Fixed conversion

  Element balance

  Balances in every element

  Conversion

  28.21 % of CH4 (assumed: scripts/nacn_balance.py: carbon not in HCN, CO2 or residual CH4 (CH4/HCN 0.018 of US 4,847,062 A, Example 1) leaves as CO (D-004))

  Catalyst

  Platinum-rhodium (90/10) gauze pack · active phase Pt-Rh

  Operating window

  1,223.2–1,473.2 K (950–1,200 °C), 100–200 kPa (1–2 bar) (given: temperature: US 6,596,251 B2 (Degussa, 2003), detailed description: reaction temperature 950-1200 C, the background naming Pt with 10 % Rh gauzes at about 980-1050 C in air operation; pressure: near-atmospheric operation of the converter, ASSUMED (no open source read in this run gives a pressure))

  Poisons

  iron, sulfur compounds
