    摘要: A method for testing catalysts in a fluidized bed reactor comprises enclosing catalyst material in capsules having pores or holes smaller than the catalyst material, inserting the capsules filled with catalyst material to into a port of the fluidized bed reactor and recovering at least a portion of the catalyst capsules from the fluidized bed reactor after use through an additional port of the fluidized bed reactor, wherein the capsules move with a flow of uplifted fluid and gas in the fluidized bed reactor.

    摘要: A process for upgrading a naphtha feed includes separating the naphtha feed into at least a light naphtha fraction, contacting the light naphtha fraction with hydrogen in the presence of at least one cyclization catalyst, and contacting the cyclization effluent with at least one cracking catalyst. Contacting the light naphtha fraction with hydrogen in the presence of at least one cyclization catalyst may produce a cyclization effluent comprising a greater concentration of naphthenes compared to the light naphtha fraction. Contacting the cyclization effluent with at least one cracking catalyst under conditions sufficient to crack at least a portion of the cyclization effluent may produce a fluid catalytic cracking effluent comprising light olefins, gasoline blending components, or both. A system for upgrading a naphtha feed includes a naphtha separation unit, a cyclization unit disposed downstream of the naphtha separation unit, and a fluid catalytic cracking unit disposed downstream of the cyclization unit.

    摘要: Separation of asphaltenes from residual oil is carried out with naphtha as solvent. In particular, straight run naphtha obtained from the same crude oil source as the residual oil feed is used as the solvent. The mixture of deasphalted oil and solvent is passed to a hydroprocessing zone, without typical separation and recycle of the solvent back to the solvent deasphalting unit. Asphalt is separated from the residual oil (residue from atmospheric or vacuum distillation); the mixture of deasphalted oil and naphtha solvent is passed to the hydroprocessing unit.
