Abstract
Low-temperature lignite pitch was thermally cracked in a 4-inch id reactor at 1,200 deg to 1,450 deg f. and pitch feed rates of 5.5, 7.0, and 9.5 Pounds per hour to produce coke, oil, and gas. Temperature had a much greater influence on product yields than pitch feed rate. Highest coke yield (30 weight-percent), was obtained at minimum pitch feed rate and 1,450 deg f. Maximum oil yield (28 weight-percent) was obtained at the lowest feed rate and intermediate temperature (1,325 deg f.). Gas yield was highest (30 weight-percent) at the lowest feed rate and maximum temperature (1,450 deg f.).
