ubber is a vinyl polymer, <strong>and</strong> is very similar <strong>to</strong> polyethylene <strong>and</strong><br />
polypropylene in structure.<br />
Polybutylene (PB-1) is a high molecular weight, linear, isotactic, <strong>and</strong> semicrystalline<br />
polymer. PB-1 replaces materials like metal, rubber <strong>and</strong><br />
engineering polymers. Because of its specific properties it is mainly used in<br />
pressure piping, flexible packaging, water heaters, compounding <strong>and</strong> hot<br />
melt adhesives.<br />
Methyl-tert-butyl-ether (MTBE) is used in <strong>gas</strong>oline <strong>to</strong> boost the octane<br />
rating <strong>and</strong> <strong>to</strong> decrease <strong>to</strong>xic emissions in the exhaust. As an octane<br />
enhancer, MTBE delivers high octane numbers at relatively low cost. A direct<br />
effect of the use of MTBE is the reduction of both "regulated" emissions (CO,<br />
unburned hydrocarbons) <strong>and</strong> "unregulated" emissions.<br />
7.3 Synthesis <strong>gas</strong> (syn<strong>gas</strong>)<br />
Synthesis <strong>gas</strong> (syn<strong>gas</strong>) is a mixture of carbon monoxide <strong>and</strong> hydrogen. It<br />
can be created from coal or methane reacting with steam at high<br />
temperatures:<br />
From coal:<br />
C + H 2 O → H 2 + CO<br />
Or from methane: CH 4 + 1/2O 2 → CO + 2H 2 Lean combustion<br />
CH 4 + H 2 O → CO + 3H 2 Steam reforming<br />
