The conversion of carbon dioxide and hydrogen into methanol and higher alcohols

Alternative thermochemical routes for aviation biofuels via alcohols synthesis: Process modeling, techno-economic assessment and comparison

“…According to this, carbon dioxide from the CO 2 separation and recovery unit reacts with H 2 in the presence of catalyst at high pressures and is converted into CO, methanol and other higher alcohols. The key process assumptions for the CCU modeling are based on the experimental study of Nieskens et al [101] and are presented in Table 10.…”

Activated Carbon‐Supported Mo‐Co‐K Sulfide Catalysts for Synthesizing Higher Alcohols from CO2

“…In particular, the synthesis of alcohols by catalytic CO 2 hydrogenation has attracted great attention because alcohol products can be applied extensively in the downstream industry and an analogical technical process (syngas conversion) has been widely commercialized. However, most studies about CO 2 hydrogenation to alcohols have focused on the synthesis of methanol , while the synthesis of C 2+ alcohols with higher added values is more challenging .…”

“…Conventional catalyst systems for the synthesis of higher alcohols via CO 2 hydrogenation include noble metal catalysts (mainly Rh‐based catalysts) , , Fischer‐Tropsch (F‐T) catalysts coupled with reverse water‐gas shift (RWGS, mainly Cu‐based) catalysts , , and homogeneous catalysts , . However, Rh‐based catalysts are expensive, RWGS and FT‐type coupled catalysts lead to high hydrocarbon selectivity, and homogeneous catalysts are difficult to recover.…”

Bromide promoted hydrogenation of CO2 to higher alcohols using Ru–Co homogeneous catalyst

“…For example, a CoMoS based catalyst produced 35.6% of C 2+ OH in alcohol products at 340 °C. 4 An alkali-promoted Mo/SiO 2 catalyst could generate alcohols at 250 °C with a C 2+ OH selectivity of 75.6%. 5 A [Rh 10 Se]/TiO 2 catalyst could catalyze the reaction at 350 °C with ethanol selectivity of 83%.…”
