Tail-end Selective HT for Removal of Acetylene in C2 Fraction

BC-H-20A/B catalyst is a new generation tail-end selective hydrogenation catalyst developed by SINOPEC. It is a multi-metal composite catalyst with high selectivity and high ethylene yield under a wide range of operating conditions. There is no need for the process to introduce CO to adjust selectivity. Compared with the previously developed catalysts of the same kind, BC-H-20A/B catalyst reduces the amount of green oil byproduct and makes the oil lighter. Hence, the green oil is not likely to stick to the catalyst surface but form coke, resulting in longer catalyst regeneration cycle and longer catalyst service life.
