Process for the manufacture of at least one ethylene derivative compound from bioethanol

摘要

Process for the manufacture of at least one ethylene derivative compound starting from bioethanol comprising dehydration of bioethanol, separation and compression to form a stream A1, division of stream A1 into two slipstreams B1 and B2, wherein slipstream B 1 is fed to a first reactor to produce at least one ethylene derivative, and slipstream B2 is fed to a second reactor to produce at least one ethylene derivative after being subjected to an oxygenates removal step and a drying step. The process may optionally include a secondary compression of slipstream B2, desulfurization of stream A1, and/or separate desulfurization of slipstreams B 1 and/or B2. In preferred embodiments, the first and second reactors comprises oxychlorination and chlorination, respectively; and the ethylene derivative compound formed in both reactor is 1,2-dichloethane.
