Abstract

Methods and systems for producing sulfuric acid and/or sulfur trioxide, which may include contacting a first stream that includes oxygen and a second stream that includes sulfur to produce a third stream that includes sulfur dioxide, and subjecting the third stream to an oxidation reaction to produce a fourth stream that includes sulfur trioxide. The contacting of the first and second streams may include contacting a molar amount of oxygen that exceeds a molar amount of sulfur.

Abstract

Methods of catalytic hydrogenation, including methods that may be used to hydrogenate an unsaturated reactant to produce an at least partially saturated product that may be a solid at 20° C. Systems for catalytic hydrogenation that may include a reactor bed containing one or more activated carbon monolith catalysts. At least 97% of unsaturated bonds may be saturated by the methods and systems.

Abstract

A carbon black monolith comprising a matrix comprising ceramic material and carbon black dispersed throughout the matrix and a method for making a carbon black monolith comprising extruding an extrudable mixture including a carbon black, a ceramic forming material, water, an extrusion aid, and a flux material. A carbon black monolith catalyst comprising a finished self-supporting carbon black monolith having at least one passage therethrough, and comprising a supporting matrix and carbon black dispersed throughout the supporting matrix and at least one catalyst precursor on the finished self-supporting carbon black monolith. A method for making and a method for use of such a carbon black monolith catalyst in catalytic chemical reactions are also disclosed.
