Tests were conducted to verify earlier yield results and at the same time to ascertain the paraffin quality to be attained. The yields expected were reached using filtering agent A (Paraflow) and increased with use of asphalt instead as filtering agent. Specific gravity of the product paraffins as corrected to a filtering-agent-free basis was about 0.782 for both filtering agents. Distillation of 80% to 82% of the paraffins lowered the specific gravity to about 0.777 or 0.778. Complete removal of oils from the product paraffins would give specific gravity of 0.777 before distillation and 0.775 after; even this process did not give a specific gravity of 0.774 for distillate paraffin as Oppau wanted. Comparison of the specific gravities 0.775 for oil-free product and 0.777 to 0.778 as actually achieved showed that the filtration process was satisfactory, since oil content of the distillate paraffin was not supposed to exceed 3% to 4%. Complete removal of oil from the paraffin could not be accomplished even by use of comparatively high pressure and temperature. Results indicated that, while Zeitz had sufficient filter surfaces to handle an increased volume, their mixing procedures were responsible for lower than necessary yields. The comparison of Zeitz material to earlier material from Leuna showed a notable increase in total yield, but a drop in paraffin distillate quality, which indicated that Leuna material had undergone better hydrogenation. 6 tables, 2 graphs.
