摘要： A method and apparatus for measuring particulates contained in the exhaust gases from internal combustion engines which dilutes the exhaust gases with prefiltered and precooled air to produce a constant volume mixture which may be sampled for exhaust gas emissions as well as for particulates. After mixing of the exhaust gases and the pretreated air, sampling of the mixture by isokinetic probes produces a uniform sample of particulate matter which is collected on temperature controlled filters for analysis.

摘要： A method for separating organometallic compounds from liquid hydrocarbons containing the same wherein the liquid hydrocarbon is contacted with a contact material comprising: an adsorbent selected from the group consisting of alumina, silica-alumina and silica gel; cupric chloride impregnated on the adsorbent; and water. The presence of water in the contact material is essential to good separation performance. The contact material may also comprise an amine which may be present either as a reaction product or a complex.
