Petrochemical catalysts

Polyphosphoric acid supported on diatomaceous earth (p. 342) is a petrochemicals catalyst for the polymerization, alkylation, dehydrogenation, and low-temperature isomerization of hydrocarbons. Phosphoric acid is also used in the production of activated carbon (p. 274). In addition to its massive use in the fertilizer industry (p. 524) free phosphoric acid can be used as a stabilizer for clay soils small additions of H3PO4 under moist conditions gradually leach out A1 and Fe from the clay and these form polymeric phosphates which bind the clay particles together. An allied though more refined use is in the setting of dental cements. [Pg.520]

Catalysis is widely used in the chemical industry, particularly in the making of gasoline and other petrochemicals. Catalysts save enormous amounts of energy. As you probably know, carbon monoxide is a poisonous gas that is found in automobile exhaust. The following oxidation reaction could remove the health hazard, but this reaction is very slow. [Pg.611]

During the same period Universal Oil Products developed olefin polymerization and hydrogenation processes and the Shell Chemical Company became interested in olefin chemistry and petrochemicals. Shell opened its Emeryville, California, research center in 1928 and developed methods for the production of alcohols, ketones, and esters from propylene and butylenes, as well as synthetic chlorohydrins, glycols, and glycerol. Many of these petroleum chemicals were produced in Martinez, California, from 1933 and the use of petrochemical catalysts became established. [Pg.262]
