✦ Synopsis

03 Gaseous fuels (sources, properties, recovery, treatment) 370°C in both reactors, and at higher space velocity. The gaseous product consisted of CO and CO;?, which amounted to about 20 to 30 wt% of bio-oil. The catalysts were deactivated due to coking and were regenerated to achieve their original activity.

Vapor liquid equilibrium and gas holdup with Yilan coal liquefaction test Takeda, T. et al. Sekiran Kagaku Kaigi Happy0 Ronbunshu, 1998, 35th, 43 l-434. (In Japanese) Liquefaction test with Yilan coal was carried out by using I t/d process supporting unit (PSU) and high pressure vapour liquid equilibrium (VLE) at the hot separator and differential pressure in the first liquefaction reactor were measured. The experimental VLE data were compared to the results cahulated by Soave Redlich Kwong (SRK) equation of state, while gas holdup was predicted from the differential pressure in the reactor. As a result, the estimated K-value of each fraction had a good agreement with the experimental value. Furthermore gas holdup data was related to the gas superficial velocity based on the SRK equation of state. 02100270
