As little as 10 mL of pure methanol when drunk is metabolized into formic acid, which can cause permanent blindness by destruction of the optic nerve. 15 mL is potentially fatal, [1] although the median lethal dose is typically 100 mL (3.4 fl oz) (i.e. 1–2 mL/kg body weight of pure methanol). [4]
The Poison Control Centre of Ain Shams University (PCC-ASU) was established in 1981. It is one of the earliest poisoning treatment facilities to be established in the Middle East. It has its own inpatient department, ICU and Analytical Toxicology unit. [21] It serves between 20 and 25 thousand cases a year.
Fomepizole is used to treat ethylene glycol and methanol poisoning. It acts to inhibit the breakdown of these toxins into their active toxic metabolites. Fomepizole is a competitive inhibitor of the enzyme alcohol dehydrogenase, [6] found in the liver. This enzyme plays a key role in the metabolism of ethylene glycol, and of methanol.
If as little as 10 ml of pure methanol is ingested, for example, it can break down into formic acid, which can cause permanent blindness by destruction of the optic nerve, and 30 ml is potentially fatal, [2] although the median lethal dose is typically 100 ml (3.4 fl oz) (i.e. 1–2 ml/kg body weight) of pure methanol.

The stored energy can be recovered by burning the methanol in a combustion engine, releasing carbon dioxide, water, and heat. Methane can be produced in a similar reaction. Special precautions against methane leaks are important since methane is nearly 100 times as potent as CO 2 , regarding the 20-year global warming potential .
It is not effective for a number of poisonings including: strong acids or bases, iron, lithium, arsenic, methanol, ethanol or ethylene glycol. [ 7 ] Although activated charcoal is the most commonly used agent for GI decontamination in poisoned patients, medical professionals use discretion when determining whether or not its use is indicated.

Methanation is the conversion of carbon monoxide and carbon dioxide (CO x) to methane (CH 4) through hydrogenation. The methanation reactions of CO x were first discovered by Sabatier and Senderens in 1902. [1] CO x methanation has many practical applications.
Gasoline synthesis: The Reactor 2 product gas is next fed to Reactor 3, the third reactor containing the catalyst for conversion of DME to hydrocarbons including paraffins , aromatics, naphthenes (cycloalkanes) and small amounts of olefins , typically with the carbon number ranging from 6 to 10. Gasoline Treatment: The fourth reactor provides ...
