    • A process for upgrading aliphatic feedstocks containing lower olefins employing new synthetic catalyst of ultra-large pore crystalline material. The new crystalline material exhibits unusually large sorption capacity demonstrated by its benzene adsorption capacity of greater than about 15 grams benzene/100 grams at 50 torr and 25.degree. C., a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 Angstrom Units and a hexagonal arrangement of uniformly sized pores with a maximum perpendicular cross section of at least about 13 Angstrom units. A new process is provied for catalytic oligomerization of lower olefin component in paraffin-containing mixed aliphatic feedstock which comprises contacting the feedstock under catalytic conversion conditions with acid metallosilicate solid catalyst having the structure of MCM-41 with hexagonal honeycomb lattice structure consisting essentially of uniform pores in the range of about 20 to 100 Angstroms. The oligomerization reaction is very selective, especially when conducted at temperature of about 40.degree. to 250.degree. C., yielding branched intermediate olefins. Low severity reaction permits execellent conversion of lower olefins at pressure of about 100-13,000 pKa range and moderate space velocity. Oligomers of propene produced over MCM-41, when reacted under cracking/disproportionation conditions yield a propylene-rich mixture which is separated as a C.sub.3 stream, and C.sub.6 + isoalkenes are recovered in good yield.
    • 一种使用新型超大孔结晶材料合成催化剂升级含有低级烯烃的脂肪原料的方法。 新的结晶材料表现出非常大的吸附能力,其吸附能力在50托和25℃时苯吸附能力大于约15克苯/ 100克,可以用大于约100的d100值进行指数的六方电子衍射图 18埃单位和具有至少约13埃单位的最大垂直截面的均匀尺寸孔的六边形排列。 提出了一种新的方法,用于在含链烷烃的混合脂族原料中的低级烯烃组分的催化低聚,其包括在催化转化条件下使原料与具有基本上由均匀孔组成的六方蜂窝晶格结构的具有MCM-41结构的酸性金属硅酸盐固体催化剂 在约20至100埃的范围内。 低聚反应非常有选择性,特别是当在约40℃至250℃的温度下进行时,产生支链中间体烯烃。 低强度反应允许在约100-13000pKa范围和适度的空间速度的压力下进行低级烯烃的非常好的转化。 在裂解/歧化条件下反应时,MCM-41产生的丙烯的低聚物产生作为C3流分离的富丙烯混合物,以良好的收率回收C6 +异烯烃。

    • Process and apparatus for upgrading paraffinic naphtha to high octane fuel by contacting a fresh virgin naphtha feedstock stream medium pore acid cracking catalyst comprising MCM-22 zeolite under low pressure selective cracking conditions effective to produce increased yield of total C4-C5 branched aliphatic hydrocarbhons. The preferred feedstock is straight run naptha containing C7+ alkanes, at least 15 wt % C7+ cycloaliphatic hydrocarbons and less than 20% aromatics, which can be converted with a fluidized bed catalyst in a vertical riser reactor during a short contact period.The isoalkene products of cracking are etherified to provide high octane fuel components.

    • High viscosity index, low pour point lubricants are produced by reacting an iso-paraffinic component, preferably with significant mono- and di-methyl chain branching, with an olefinic reactant in the presence of a free radical generator such as an organic peroxide, preferably ditertiary butyl peroxide. The isoparaffinic reactant is preferably obtained by the isomerization of a waxy feed such as slack wax over a zeolite beta isomerization catalyst, preferably Pt/zeolite beta. The olefinic reactant is preferably a distillate fraction produced by the oligomerization of low molecular weight olefins e.g., C.sub.3 to C.sub.5 olefins, produced by oligomerization over an intermediate pore size zeolite oligomerization catalyst such as ZSM-5.
