Abstract

The results of the hydrogenation of coal from the Zashulanskoe deposit in the Chita oblast under conditions of a short reaction time (no longer than 10 min) are given. It was found that, to reach a 78–80% degree of coal conversion under the conditions of high-speed heating (∼200 K/min), the reaction time can be no longer than 10 min (the coal: paste-forming agent ratio = 50: 50), which corresponds to a feed space velocity of 2.5–3.0 kg l−1·h−1. This value, which determines the process productivity of coal hydrogenation, is higher by a factor of 3–3.5 than that under analogous conditions used in second generation processes, which were developed in the 1990s.
