(Specification)Standard Specification for Benzene for Use with Zeolite Based Catalysts
Standard Specification for Benzene for Use with Zeolite Based Catalysts
ABSTRACT
This specification covers benzene for use with zeolite based catalysts. Tests shall be performed to determine the property requirements of benzene in accordance to the following test methods: benzene weight percentage; sulfur mass; thiophene mass; toluene mass; nonaromatic hydrocarbons weight percentage; nitrogen mass; acid wash color; bromine index, water, and appearance.
SCOPE
p>1.1 This specification covers benzene for use with zeolite based catalysts.
1.2 The following applies to all specified limits in this specification: for purposes of determining conformance with this specification, an observed value or a calculated value shall be rounded off "to the nearest unit" in the last right-hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice E 29.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 Consult current OSHA regulations, supplier's Material Safety Data Sheets, and local regulations for all materials used in this specification.
