Methanol (EHC 196, 1997)

Compared with absorption via the respiratory tract, exposure of one hand to liquid methanol for only 2 min would result in a body burden of as much as 170 mg methanol, similar to that resulting from exposure to an approximate air concentration of 50 mg/m 3 (40 ppm) methanol for 8 h (Dutkiewicz et al., 1980). It was also reported that in the .

Bioethanol is a green fuel which is obtained when the starch and sugar of corn, crops, potatoes, cane, rice etc, is fermented by yeast cells into ethanol. By the application of power ultrasonics, the plant cells are disrupted and the intracellular material is extracted so that the feedstock is better available for the enzymatic digestion.

Production of Methanol - an overview | ScienceDirect Topics

A methanol plant of 400,000 t/y that uses a Lurgi reactor for the synthesis reaction, was simulated to obtain mass and energy balances. Although the total amount of required H 2 increases with the CO 2 content up to H 2 /CO 2 ≈ 2, it is considerably lower than the quantity required by direct CO 2 hydrogenation processes.

Ethanol is non-toxic and available as it can be produced renewably by fermentation of biomass [8]. Since the 1970s, Brazil has started developing ethanol as a major fuel source. More recently, the USA has become a major ethanol producer, with production doubling from 8 billion L.yr−1 in 2002 to 15 billion L.yr−1 in 2005 and increasing .
