CO+2H2CH3OHCO+3H2CH4+H2OH2=104.69kJ/molHHk=198.28kJ/mol Pure carbon monoxide is used as a feed stream, but the hydrogen stream contains 2% of methane. The reactions take place at temperature 340C. Allowable temperature range for these reactions are 300400C. Whether the reactor is operated adiabatically or isothermally? Justify your answer with calculations. Consider 100moles/h of methanol production and selectively as 0.8 . The specific heats in J/molK of CO=28.95,H2=28.84, CH3OH=52.29,CH4=34.31,H2O=33.46. Consider feed rate (per hour) to the reactor as 200 moles CO,600 moles H2,250 moles CH4.1Btu=1055J and 1lb=453.3g
