MICROWAVE-ASSISTED CATALYTIC PYROLYSIS PROCESS AND REACTOR FOR SELECTIVELY CONVERTING ADDITIVE-CONTAINING PLASTIC ALKENES AND ALKANES

The present disclosure provides a pyrolysis process for converting an additive-containing plastic comprising a polyolefin polymer to an alkene, an alkane, or a mixture thereof. The process comprises contacting the plastic with a catalyst in a one-pot pyrolysis system at a temperature between about 350 C. and about 500 C.; wherein the catalyst comprises a solid acid selected from the group consisting of HY, HZSM-5, and Al-SBA-15. The present disclosure further provides a one-pot pyrolysis system and uses of a solid acid in the pyrolysis process for converting plastic comprising a polyolefin polymer to an alkene.

Diesel oxidation catalyst

An oxidation catalyst composite, methods, and systems for the treatment of exhaust gas emissions from a diesel engine are described. More particularly, described is an oxidation catalyst composite including a first oxidation component comprising a first refractory metal oxide support, palladium (Pd) and platinum (Pt); a NO.sub.x storage component comprising one or more of alumina, silica, titania, ceria, or manganese; and a second oxidation component comprising a second refractory metal oxide, a zeolite, and Pt. The oxidation catalyst composite is sulfur tolerant, adsorbs NO.sub.x and thermally releases the stored NO.sub.x at temperature less than 350 C.

20250270454 · 2025-08-28 ·

Catalysts and corresponding methods are provided for conversion of Fischer-Tropsch wax to distillate boiling range products. The catalysts can correspond to noble metal catalysts supported on a support that includes a 3-dimensional zeotype and a substantially non-acidic or low acidity oxide binder. It has been discovered that using a substantially non-acidic or low acidity binder allows for improved yield of distillate boiling range products when cracking Fischer-Tropsch wax. It has further been discovered that by using a support including a 3-dimensional zeotype, the temperature for achieving a target level of conversion during hydrocracking can be reduced or minimized
