Effect of hydrogen on materials

Metals that work successfully at low temperatures include aluminum and its alloys, copper and its alloys, nickel and some of its alloys, as well as austenitic stainless steels.

Effects of hydrogen pressure, materials yield strength, and temperature on the fracture toughness (fCIH) of three low-alloy vessel steels (a) pressure, (b) yield strength, and (c) temperature. 

Table IV shows the reactivities of raw materials and products on a nickel-activated carbon catalyst and the effect of hydrogen on the reactions. When carbon monoxide and hydrogen were introduced into the catalyst, no product was formed. Thus, the hydrogenation of CO does not proceed at all. When methyl iodide was added to the above-mentioned feed, 43% of the methyl iodide was converted to methane. In the presence of methyl iodide small amounts of methane, methanol, and acetic acid were formed from methyl acetate, while small amounts of methane and acetic acid were also formed from acetic anhydride. Hydrogen fed with methyl acetate accelerated the formation of methane and acetic acid remarkably.

The effects of hydrogen on the thermal cracking of bitumen are obvious in the results. Most dramatically, high carbon residue material is converted in virtually 100% yields to liquid and gaseous products. The effect is most pronounced for the... 

Hydropyrolysis processing is probably best suited for those feedstocks which can best utilize the inhibition effects of hydrogen on polymerization, condensation, and aromatization reactions. Such feedstocks are high molecular weight naphthenic materials which are susceptible to cracking but are easily converted to coke by liquid-phase bimolecular reactions.

The design and construction of small-scale pilot-plant units for processing under extreme conditions of pressure and temperature have been described. This description includes material on constructing barricades, thick-walled pressure vessels, and pumps as well as information on the selection of alloys and the effects of hydrogen on the properties of metals.
