“…The maximum produced reaction heat is 8.5W and not very significant compared to the oven duty in this laboratory setup. In this small lab setup, the energy input per kg MeOH is too high under the current condition, because it is about three times the higher heating value of methanol (22.4MJ/kg [4]). However, this energy input includes heat loss to the environment and the loss of the cooling duty.…”

“…First, the exothermic character of the synthesis reaction implies a need for good temperature control [4], although the reaction of CO 2 with H 2 to methanol shown in equation (4) is less exothermic than the reaction starting from CO in equation (3). Secondly, and most important, thermodynamic equilibrium constraints induce a limited single pass conversion, especially when using CO 2 [5,6].…”

“…Heat is removed on both sides of the catalyst bed by the boiling water surrounding the tubes as well as by the feed gas introduced into the inner tube (Tijm et al 2001). A high conversion rate (about 14 % methanol in the reactor outlet) is cited for this reactor (Fiedler et al 2003).…”

“…In 1966, ICI introduced a new, more active Cu/ZnO/Al 2 O 3 catalyst that began a new generation of methanol production by using a low temperature (220-275°C), low pressure process (50-100 bar). The last high temperature methanol synthesis plant closed in the mid-1980s (Fiedler et al 2003) and, at present, low temperature low pressure processes based on Cu catalysts are used for all commercial production of methanol from syngas. The synthesis process has been optimized to point that modern methanol plants yield 1 kg of MeOH /liter of catalyst/hr with >99.5% selectivity for methanol.…”
