Comparison of different catalysts for hydrogenation of coal coke oven tar in the liquid phase

This report was an abstract of results from an experiment carried out for one year (June 1943--June 1944) for comparison of I. G. catalyst 11002 (2% MoO/sub 3/ on carbonization coke) with the ''Ersatz'' catalyst 10927 (about 10% FeSO/sub 4/ on carbonization coke). Tests had formerly been made only in large-scale operations. Results were poorly comparable because of the difference in reaction conditions and in the injection feed. In the tests conducted for this report, these factors remained constant with: injection feed--70% coke oven tar and 30% fuel oil, catalysts--1% to 4% of injection, throughput of 1 kg/liter/hr, temperature of 24.0 mV, pressure about 700 atm, gas being made-up gas, and feed:gas ratio being 1:4500. Catalyst 11002 was found to be much superior to any other catalysts tested. Catalyst 10927 was next best with 3% of it being equivalent to 1% of 11002. Attempts to prepare still more active catalysts had no positive results. Activated Fullers earth or diatomaceous earth were used as the carriers and either very small amounts of Mo or Cr or high concentration of iron was deposited on them.
