摘要:
A method of operating a multi-phase downflow reactor so as to induce a pulsing flow regime is disclosed. The pulse may be induced by increasing the gas rate while maintaining the liquid rate until a pressure drop sufficient to induce the pulse flow is achieved. The method is particularly useful in the sulfuric acid catalyzed alkylation of olefins in a reactor packed with a stainless steel/polypropylene mesh.
摘要:
Low value hydrocarbons can be upgraded by contact with the products formed during irradiation of a hydrogen donor using microwave energy in the presence of at least one plasma initiator.
摘要:
Arc heater apparatus and method for producing acetylene from heavy hydrocarbons characterized by arc heater means for producing arc heated plasma gas forming a downstream reaction zone, wall means forming a plenum chamber having a substantially vertical axis and surrounding the reaction zone, inlet means upstream of the arc heated plasma gas for introducing heavy hydrocarbons into the chamber, and the walls of the chamber flaring downwardly outwardly to minimize the deposit of solid reaction products on the walls.
