A method of removing contaminants from a contaminated organic-based feed stream, comprising the steps of:
- (a) providing a layer of reticulated ceramic material in a chemical reactor, the layer of reticulated ceramic material being in an amount sufficient to filter the contaminant from the organic-based feed stream and the reticulated ceramic material having a pore distribution range of about 10 to 800 pores per linear inch;
- and
- (b) passing the contaminated organic-based feed stream through the layer of reticulated ceramic material.
A method of removing contaminants from a contaminated organic-based feed stream in a chemical reactor, comprising the steps of:
- (a) providing a layer of a reticulated ceramic material, the reticulated ceramic material having a pore distribution range of about 10 to 800 pores per linear inch in the chemical reactor;
- and
- (b) contacting the contaminated organic-based feed stream with the reticulated ceramic material to remove the contaminants from the contaminated organic-based feed stream.
A method of fluid distribution in a chemical reactor comprising the steps of:
- (a) providing a layer of reticulated ceramic material in the chemical reactor, the reticulated ceramic material having a plurality of web members defining a plurality of flow passageways through the reticulated ceramic material;
- (b) contacting an organic-based feed stream with the layer of reticulated ceramic material;
- and
- (c) subdividing the organic-based feed stream into a plurality of smaller fluid streams by passing the organic-based feed stream through the plurality of flow passageways defined by the web members of the reticulated ceramic material.
A method of retaining catalyst material forming a fixed catalyst bed comprising the steps of:
- (a) providing a layer of reticulated ceramic material the reticulated ceramic material having a pore distribution range of about 10 to 800 pores per linear inch;
- (b) contacting an organic-based feed stream containing the catalyst material with the reticulated ceramic material;
- (c) removing the catalyst material from the organic-based feed stream;
- and
- (d) providing a relatively catalyst-free organic-based stream for further processing.
A method of filtering sediments formed in a fixed catalyst bed comprising the steps of:
- (a) providing a layer of reticulated ceramic material the reticulated ceramic material having a pore distribution range of about 10 to 800 pores per linear inch;
- (b) contacting an organic-based feed stream containing the sediments with the reticulated ceramic material;
- (c) removing the sediments from the organic-based feed stream;
- and
- (d) providing a relatively sediment-free organic-based stream for further processing.
A method of streamlining turbulent flow of a vapor to a chemical reactor having a vapor;
- comprising the steps of:
- (a) providing a layer of a reticulated ceramic material in a vapor inlet to the chemical reactor, the reticulated ceramic material having a plurality of web members defining a plurality of flow passageways through the reticulated ceramic material;
- (b) passing a vapor feed stream through the vapor inlet to the chemical reactor with the reticulated ceramic material;
- (c) subdividing the feed stream into a plurality of smaller fluid streams by passing the feed stream through the plurality of flow passageways defined by the web members of the reticulated ceramic material;
- and
- (d) discharging the streamlined vapor feed stream into the chemical reactor.
