摘要:
An apparatus and process for removing impurities from silicone based solvents is presented. The apparatus and process use an adsorbent for removing contaminants from the solvent, and when the adsorbent is sufficiently loaded with contaminants, the adsorbent is regenerated. The regeneration process entails a two stage heating process for recovery of solvent and removal of contaminants.

An adsorbent for removal of impurities from silicone based solvents is presented. The adsorbent is regenerable for repeated use in cleaning silicone based solvents.
摘要:
A process and adsorbent for removing contaminants from silicone based solvents is disclosed. The process provides for cleaning a solvent for reuse, and regeneration of the adsorbent. The adsorbents are for adsorbing organic and inorganic compounds that have accumulated in the silicone solvents.
摘要:
A process for the use in the oligomerization of olefins is presented. The process produces a gasoline boiling range product having a high research octane number and almost no aromatics content. The process utilizes a solid catalyst comprising a zeolite that is treated with a phosphorous containing reagent to generate a catalyst having phosphorous content between 0.5 and 15 wt %.
摘要:
A liquid or partially liquid phase process for isomerizing a non-equilibrium mixture of xylenes and ethylbenzene uses a zeolitic catalyst system preferably based on zeolite beta and on pentasil-type zeolite. The invention obtains an improved yield of para-xylene from the mixture relative to prior art processes in a more economical manner. A preferred beta zeolite is a surface-modified zeolite beta resulting from acid washing of a templated native zeolite at conditions insufficient to effect bulk dealumination. A preferred pentasil zeolite is a MTW-type with a silica-to-alumnina ratio between 20 and 45.
摘要:
Applicants have developed a process for the oxidation of ketones to esters. The process involves contacting the ketone with hydrogen peroxide and a catalyst at oxidation conditions. The catalyst is a molecular sieve represented by the empirical formula: (MwSnxTiySi1−x−y−zGez)O2 where M is a trivalent metal such as aluminum or boron. These molecular sieves have a microporous three dimensional framework structure of at least SiO2 and SnO2 tetrahedral units, a crystallographically regular pore system and the characteristic x-ray diffraction pattern of zeolite beta.
