The present disclosure sets forth a proposed solution to decarbonize the acrylic chemicals industry with a lactic-to-acrylic technology producing bio-based acrylics that are sustainable and eco-friendly and are at cost parity with petrochemicals. In the present disclosure, catalysts comprising potassium and zeolites were relied on as the catalyst base. It has been found high yield lactic-to-acrylic technology of the present disclosure is industrially feasible at new or as an add-on to existing bio-refining facilities throughout the Midwest due to the high yields achieved.

A method of preparing an aromatization catalyst comprising contacting a zeolitic support with a metal-containing compound and a boron-containing compound to produce an impregnated support, and contacting the impregnated support with an activating composition to produce an aromatization catalyst, wherein the activating composition comprises a chlorine-containing compound and a fluorine-containing compound, and wherein the impregnated support is heated in the presence of the activating composition to a temperature in the range of from about 100 C. to about 500 C.

Small crystal LTL framework type zeolites, characterized as polycrystalline aggregates, each of the aggregates comprising a plurality of spherical or cube-like crystallites and wherein each crystallite has an average crystallite size of from 10 to 50 nm, are disclosed. Such zeolites can be prepared by hydrothermal conversion of FAU framework type zeolites at low H.sub.2O/SiO.sub.2 mole ratios.
