Effective hydrogenation of carbonates to produce methanol over a ternary Cu/Zn/Al catalyst

Low temperature methanol synthesis from CO hydrogenation over Cu-based catalyst

A b as well as methanol selectivity (~90%) were achieved with a mass space velocity of 2700 L/h.kg-cat. at 433 K and 5.0 MPa via ethyl formate in slurry phase. This study investigated the influences of co-precipitation PH value of copper magnesium catalyst, types of alkali compounds as carbonylation promoters and impregnation agents, alcohol solvent on the reaction performances. It was also fou...

CO2 Reforming of Coke Oven Gas Over a Ni/γAl2O3 Catalyst to Produce Syngas for Methanol Synthesis

The CO2 reforming of coke oven gases (COG) was carried out over a Ni/γAl2O3 catalyst in order to obtain a suitable syngas for methanol synthesis. The influence of different operating conditions, such as temperature and volumetric hourly space velocity (VHSV), was studied. It was found that the H2 present in the feed gas promotes the Reverse Water Gas Shift reaction (RWGS), which produces water....

Hydrogenation of carbon dioxide to methanol by using a homogeneous ruthenium-phosphine catalyst.

Conversion of Methanol to Hydrocarbons over Ni-zsm-5 Catalyst

As stock of crude oil is limited, new resources for fuel and petrochemicals are required to be developed. Natural gas or biogas can be easily converted into methanol which can be converted into gasoline and olefins. This study uses zeolite catalyst (ZSM-5) and its modification by Ni to convert methanol to hydrocarbons (MTH). Catalysts are studied at different temperatures and at different loadi...

A highly selective and stable ZnO-ZrO2 solid solution catalyst for CO2 hydrogenation to methanol

Although methanol synthesis via CO hydrogenation has been industrialized, CO2 hydrogenation to methanol still confronts great obstacles of low methanol selectivity and poor stability, particularly for supported metal catalysts under industrial conditions. We report a binary metal oxide, ZnO-ZrO2 solid solution catalyst, which can achieve methanol selectivity of up to 86 to 91% with CO2 single-p...
