REACTOR SYSTEM

摘要

"REACTION SYSTEM" The reactor system of this invention comprises one or more 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. In reactor systems calling for more than one reaction chamber, the chambers are vertically spaced or stacked and reactant stream is processed serially through said reaction chambers. A reactant stream is 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.
