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 reticulated ceramic material in a chemical reactor, the reticulated ceramic material having an average pore size of about 100 to about 150 microns, the layer of reticulated ceramic material being in an amount sufficient to filter the contaminant from the contaminated organic-based feed stream;
- 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 an average pore size of about 100 to about 150 microns;
- 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 an average pore size of about 100 to about 150 micons defined by a plurality of web members forming a plurality of flow passageways through the reticulated ceramic material;
- (b) contacting an organic-based feed stream with the layer of 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 formed by the web members of the reticulated ceramic material.
A method of removing organically bound iron contaminants from an organic-based feed stream comprising contacting the feed stream in the presence of hydrogen with a layer of reticulated ceramic material, the reticulate ceramic material having an average pore size of about 100 to about 150 microns, and organic-based feed stream being selected from the group consisting of organically bound iron contaminated petroleum crude oil, topped or reduced crude oil, solvent deasphalted oil, distillate, heavy cycle stocks, visbreaker liquid effluent, atmospheric and vacuum crude tower bottoms, shale oils, coal tars and tar sand oils.
