Answer 1

2CH4---(1500градусов)---> C2H2+ 3H2 3C2H2---(650 градусов+ акт. уголь)--> C6H6 C6H6+ 3H2--температура+ кат. Ni--> C6H12

Answer 2

Equations for the given transformations:

1. Conversion of methane (CH4) to ethyne (C2H2): - Equation: 2 CH4 → C2H2 + 3 H2 - Conditions: High temperature (around 900-1000°C) and the presence of a catalyst such as platinum or palladium [[1]].

2. Conversion of methane (CH4) to benzene (C6H6): - Equation: 6 CH4 → C6H6 + 9 H2 - Conditions: High temperature (around 500-700°C) and the presence of a catalyst such as zeolite or alumina [[2]].

3. Conversion of benzene (C6H6) to cyclohexane (C6H12): - Equation: C6H6 + 3 H2 → C6H12 - Conditions: High temperature (around 200-250°C) and the presence of a catalyst such as platinum or palladium [[3]].

Please note that these reactions are simplified representations and may involve more complex reaction mechanisms in practice.
