Catalytic production of hydrogen by steam reforming of methanol is an attractive option for use in decentralised production of clean electrical energy from fuel cells. Methanol fuelled solid polymer fuel cell systems are promising candidates for stationary and mobile applications such as passenger cars. Present methanol reformers are usually of the packed bed type which suffer from problems suc...

Methanol has become a widely used and globally distributed product. Methanol is very important due to the current depletion of fossil fuels. Industrially, methanol was produced from the catalytic reaction of synthetic gas composed of hydrogen, carbon monoxide, and carbon dioxide. Methanol production has brought great attention due to the carbon dioxide as the main source of greenhouse gas emiss...

A solar based integrated system for hydrogen and methanol production is investigated. Energy and exergy analyses of a hydrogen production plant, thermodynamic assessment of a methanol synthesis plant, and exergy analysis of the integrated solar based system for hydrogen and methanol production, are performed. The analysis of hydrogen production is performed for the methanol synthesis procedure....

Highly siliceous ZSM-5 nanocatalysts can dehydrate methanol to a wide range of hydrocarbons. In this study, the development of hierarchical H-ZSM-5 nanocatalysts (Si/Al=200) were reported for the methanol-toolefins (MTO) reaction. The nanocatalysts were prepared through a hydrothermal technique and treated by NaOH desilication. The parent and desilicated nanocatalysts were characterized using F...

Molecular water promoted co-conversion of bicarbonate and methanol into formate over a Pd–Cu catalyst: H2-free approach for reduction.

UNLABELLED ΒACKGROUND: The methylotrophic yeast Pichia pastoris has become an important host organism for recombinant protein production and is able to use methanol as a sole carbon source. The methanol utilization pathway describes all the catalytic reactions, which happen during methanol metabolism. Despite the importance of certain key enzymes in this pathway, so far very little is known abo...

a micro-channel heat exchanger reactor with different micro-baffle shapes has been studied numerically. governing equations were solved base on the finite volume method with fluent software. in upper section, oxidation reaction of methanol was occurred and in lower section, steam reforming of methanol was done. two sections were separated with solid part which played as heat exchanger and trans...

the esterification of free fatty acids (ffa) with methanol is studied using sulfonated porous carbon (spc) as catalyst. in compare to the amorphous sugar catalyst and protonated nafion, the proposed catalyst shows stability and high efficient performance in biodiesel production. the highest initial rate of oleic acid conversion is obtained at catalyst loading of 1 mmol h+ and mole ratio of meoh...

Recent developments in separation enhanced reaction processes using membranes and adsorbents, highlighted here, have proven their potential for carbon dioxide conversion to methanol dimethyl ether.

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...
