Abstract: A method of producing olefins and/or aromatics is disclosed. The method includes catalyzing a hydrocarbon cracking reaction with a catalyst comprising a mixture of ZSM-5 zeolite and USY zeolite modified with lanthanum. The cracking process includes providing a diluent comprising primarily methane to the reactor, wherein steam is not provided to the reactor as a diluent.

Abstract: Systems and methods for producing aromatics are disclosed. A mixture of hydrocarbons having an initial boiling point of less than 250° C. with catalyst in a fluidized bed under reaction conditions effective to produce one or more aromatics. The reaction conditions include an average solids volume fraction of the fluidized bed in a range of 0.35 to 0.45.

Abstract: An electrical insulating property tester includes a guaranteed voltage applying unit for applying a guaranteed voltage to a running line provided with an electrical insulating layer around an electrical conducting wire, a grounding unit arranged downstream of the guaranteed voltage applying unit, for grounding the running line to thereby remove electric charge electrostatically induced on the running line, and a test voltage applying unit arranged downstream of the grounding unit, for applying a test voltage lower than the guaranteed voltage to the running line, to thereby detect a leakage current value.
