Abstract
A crystalline low-aluminum boron beta zeolite is used for dewaxing hydrocarbonaceous feeds.
Claims4
A method for dewaxing hydrocarbonaceous feeds by contacting the feed under dewaxing conditions with a catalyst comprising a zeolite having a mole ratio of an oxide, selected from silicon oxide, germanium oxide and mixtures thereof to an oxide selected from boron oxide, or mixtures of boron oxide with aluminum oxide, gallium oxide or iron oxide, greater than 10:1 and wherein the amount of aluminum is less than 0.10% by weight and having the x-ray diffraction lines of Table 1(b).
