Work continued in the effort to develop catalysts and a process for the production of hydrogen from heavier fuels. Progress was made in developing the calculations required to compare the experimental results from the autothermal reforming of No. 2 oil with those predicted by thermodynamic equilibrium. A computer program called ATR-6 facilitates these calculations. A prescreening test is being developed to study steam reforming catalysts under controlled conditions with mixtures of pure compounds. A gas chromatograph was installed and some preliminary runs with ethane were made. A screening test was developed to evaluate steam reforming catalysts under autothermal reforming conditions. During this development work, it was demonstrated that a monolithic CPO catalyst could be started under rich conditions. The catalytic partial oxidation of No. 2 oil produced considerable quantities of olefins (including butadiene) and unreacted oil was also observed. In preliminary runs it was shown that this small test unit was not adiabatic. These early tests also demonstrated that a rhodium containing catalyst is better for steam reforming olefins than a nickel containing catalyst. By adding heat to the reformer section in the amount to compensate for heat losses from this small unit, catalysts could be tested under conditions to be expected from an adiabatic rig. By operating at higher space velocities (about 21,000 V/Hr/Vc) it is possible to distinguish among catalysts during a test lasting 5 to 10 hours.
