Abstract
The reactor system of this invention comprises two or more vertically spaced or stacked reaction chambers each of which contains two or more vertically positioned annular-form catalyst-retaining sections existing side-by-side, each of said catalyst-retaining sections being defined by an inner tubular-form catalyst-retaining screen coaxially disposed within a vertically positioned outer tubular-form catalyst-retaining screen. Catalyst particles are movable through the resulting annular-form catalyst sections in a dense phase via gravity flow. A reactant stream is processed serially through said reaction chambers, and contacted with catalyst within said annular-form catalyst-retaining sections in a manner to promote uniform flow of reactants across said sections. The disclosed reactor system is of particular advantage with respect to a relatively low pressure hydrocarbon conversion process.
