摘要：This paper proposed an integrated mild-liquefaction and carbonization.technology for the efficient conversion of low rank coals. Simultaneously, preliminary investigations on the product distributions and characterizations of the proposed technology were made in simulated process conditions. In suitable mild-liquefaction conditions (390-450 degrees C, 8.4-11.6 MPa), the yields of liquid products and semi-cokes are up to 23.4-33.3% and 49.6-68.7%, respectively. The produced liquid products, which are predominantly abundant with paraffins (Le., alkanes and alkanes), alkyl benzenes (Le., benzene and its derivatives), and alkyl naphthalenes (i.e., naphthalene and its derivatives), are potentially utilized to produce liquid fuels by further refining. The produced semi-cokes are suitably utilized as high carbonaceous solid fuels. Also, some semi-cokes can be potentially utilized for the coking of blending coals. The adopted carbonization process in the proposed technology is convenient and efficient for the separation of liquid and solid mixtures from liquefaction. Summarily, the proposed technology is greatly potential for the conversion of low rank coals into liquid products and semi-cokes. (C) 2016 Elsevier B.V. All rights reserved.
