The selectivity, activity and stability of a zeolite hydrocracking catalyst for producing mid-distillates from feedstocks boiling above 700 DEG F (371 DEG C) are improved by using a LZ-10 whose surface area and crystallinity have been increased by selective extraction, particularly with an acid, suc ...
