We have developed a highly efficient catalyst for isobutane alkylation with butane-butylene fraction, which catalyst exhibits high levels of selectivity, activity, stability and regenerability. Several thousand hours of pilot trials.
We have developed a continuous mode of zeolite-catalyzed alkylation which combines a consecutive alternation of standard and supercritical conditions with in-situ regeneration. This allowed us to significantly increase the zeolite catalyst cycle length and efficiency (know-how).
