Methanol can be converted to olefins using zeolite and SAPO-based heterogeneous catalysts. Depending on the catalyst pore size, this process can afford either C2 or C3 products, which are important monomers. [6] [7] Methanol to olefins technology is widely used in China in order to produce plastics from coal gasification.
A larger scale application is methanol to olefins, which produces ethylene and propylene. [2] In contrast to the situation for carbon monoxide and methanol, methane and carbon dioxide have limited uses as feedstocks to chemicals and fuels. This disparity contrasts with the relative abundance of methane and carbon dioxide.
The STG+ technology offers several differentiators that distinguish it from other methanol to gasoline processes. These differences include product flexibility, durene reduction, environmental footprint and capital cost. Traditional methanol to gasoline technologies produce diesel, gasoline or liquefied petroleum gas. [10]

In organic chemistry, olefin metathesis is an organic reaction that entails the redistribution of fragments of alkenes (olefins) by the scission and regeneration of carbon-carbon double bonds. [ 1 ] [ 2 ] Because of the relative simplicity of olefin metathesis, it often creates fewer undesired by-products and hazardous wastes than alternative ...
Carbon Recycling International (CRI) is an Icelandic limited liability company which has developed a technology designed to produce renewable methanol, also known as e-methanol, from carbon dioxide and hydrogen, using water electrolysis or, alternatively, hydrogen captured from industrial waste gases.
Methanol and its vapours are flammable. Moderately toxic for small animals – Highly toxic to large animals and humans (in high concentrations) – May be fatal/lethal or cause blindness and damage to the liver, kidneys, and heart if swallowed – Toxicity effects from repeated over exposure have an accumulative effect on the central nervous system, especially the optic nerve – Symptoms may ...
Formaldehyde is produced industrially by oxidative dehydrogenation of methanol. This reaction can also be viewed as a dehydrogenation using O 2 as the acceptor. The most common catalysts are silver metal, iron(III) oxide, [7] iron molybdenum oxides [e.g. iron(III) molybdate] with a molybdenum-enriched surface, [8] or vanadium oxides.
