摘要： A process for isoparaffin-olefin alkylation is provided that permits the use of solid acid catalysts which require frequent regeneration and high isoparaffin/olefin ratios. The process comprises circulating in a reactor a slurry comprising solid acid zeolite catalyst particles (20-2000 microns) and feed of liquid reactants comprising isoparaffins and olefins in an isoparaffin to olefin molar ratio of less than 100, recycling a first portion of said slurry to provide an isoparaffin to olefin molar ratio in the reactor of at least 500, passing a second portion of the slurry to a separating means to separate alkylate product from said solid catalyst particles, and regenerating the catalyst particles.

摘要： In the conversion of coal to gaseous and liquid products, the heat value of the coal is more completely retained by the products through the selective high efficiency conversion of coal to a low ratio syngas utilizing a portion of the Fischer-Tropsch generated heat recovered as steam, conversion of the low ratio syngas with a water gas shift F-T catalyst to a product comprising C.sub.1 to C.sub.50 hydrocarbons and oxygenates, converting the F-T product to premium gas and increased liquid fuels comprising gasoline and distillate with a special zeolite catalyst and recovering the SNG and LPG products of the selective steps to provide an improved product slate. A portion of the produced fuel gas is used in lieu of coal to provide some of the heat energy requirements of the combination process.

摘要： A process for producing lubricant oils of low pour point and high viscosity index by first carrying out a partial dewaxing of a lubricant base stock in an initial catalytic dewaxing operation, followed by a selective dewaxing step. The initial catalytic dewaxing step is carried out using a large pore, high silica zeolite dewaxing catalyst such as high silica Y or zeolite beta which dewaxes by isomerizing the waxy components of the base stock to less waxy brance chain isoparaffins but the severity of the operation is controlled so as to effect only a partial removal of the waxy components. Further removal of the waxy components is effected during the subsequent dewaxing step which is selective for the removal of the more waxy n-paraffin components, leaving the branched chain isoparaffins which contribute to a high VI in the product. The selective dewaxing step may be either a solvent, e.g. MEK dewaxing operation or a catalytic dewaxing using a highly shape selective zeolite such as ZSM-22 or ZSM-23. The severity of the initial catalytic dewaxing operation may be controlled so as to effect a net increase in the content of isoparaffins and because of the selective nature of the solvent dewaxing step, this increased isoparaffins concentration may be retained, producing a product of high VI. The pour point of the feedstock is preferably reduced during the initial catalytic dewaxing step to a value which is no lower than 10.degree. F. and preferably no lower than 20.degree. F., above the target pour point for the products. Generally, this will entail a reduction of at least 10.degree. F. and preferably at least 20.degree. F. in the pour point of the feed.

摘要翻译： 首先在初始催化脱蜡操作中进行润滑剂原料的部分脱蜡，然后进行选择性脱蜡步骤，生产低倾点和高粘度指数的润滑油的方法。 初始催化脱蜡步骤使用大孔，高二氧化硅沸石脱蜡催化剂如高二氧化硅Y或沸石β进行，该脱蜡通过使基础油料的蜡质组分异构化成较少的蜡状分支链异链烷烃，但操作的严重性是 被控制以仅影响蜡组分的部分去除。 在随后的脱蜡步骤中进一步除去蜡状组分，该脱蜡步骤选择性地除去更多的蜡状正链烷烃组分，留下有助于产物中高VI的支链异链烷烃。 选择性脱蜡步骤可以是溶剂，例如 MEK脱蜡操作或使用ZSM-22或ZSM-23等高选择性沸石的催化脱蜡。 可以控制初始催化脱蜡操作的严重性，以便实现异链烷烃含量的净增加，并且由于溶剂脱蜡步骤的选择性，可以保留这种增加的异链烷烃浓度，从而产生高VI的产物。 原料的倾点优选在初始催化脱蜡步骤期间降低至不低于产物的目标倾点的10°F，优选不低于20°F的值。 通常，这将导致在进料的倾点下降至少10°F，优选至少降低20°F。
