Steam pretreatment for coal liquefaction. [Monthly report], August 1, 1993--August 31, 1993
Rapid heating liquefaction of steam pretreated Illinois No.6 coal mixed with 13X zeolite was carried out this month. The pores of this zeolite retain pyridine during drying, but not enough to account for the low apparent yield of pyridine extract. Soxhlet extraction analysis of the product showed a significantly lower oil yield compared with 5A zeolite. This might be caused by retention of tetralin in 13x zeolite pores. Tetralin retention will be determined subsequently. A test of 4A zeolite is planned for next month. Aquathermolysis of model compound {beta}-benzylnaphthyl ether was carried out this month at high pressure (liquid water conditions). Analysis of the recovered products are now in progress.
