A study has been made using laboratory-scale equipment, of the interaction of the ramjet fuel, tetrahydromethylcyclopentadiene dimer T-H Dimer, with submarine habitability equipment the COH2 catalytic burner and the activated carbon bed. It was found that ppm quantities of T-H Dimer in air were about 90 oxidized during one pass over hopcalite catalyst at 316C 600F. The T-H Dimer had a poisoning effect on the hopcalite, permanently reducing its activity. Activated carbon adsorbed an amount of T-H Dimer equal to 30 of its own weight. The autogenous ignition temperature of the carbon saturated with 30 wt of T-H Dimer is the same as that of the liquid T-H Dimer. It is in the 249C 480F to 254C 490F temperature range.
