Abstract: The invention pertains to improved lubricating oil dispersants wherein a fractionating polymer is prepared prior to functionalization (e.g., in the Koch reaction) for making dispersant additives. In one aspect, it was discovered that by fractionating a polymer to remove light hydrocarbon and unreacted monomer from the polymer before the carbonylation step of the Koch reaction, the amount of light ester impurities generated was minimized. Light ester is an undesirable byproduct that adversely affects the recycle of the catalyst from the functionalization step of the Koch reaction. The invention also pertains to improved lubricating oil nitrogen-containing dispersant additives derived from fractionated polymer.

Abstract: Multigrade lubricating oils for use in lubricating internal combustion engines, using basestocks with low levels (<75 mass %) of saturated hydrocarbons, comprise less than 3 mass % of ashless dispersant derived from a polymer of number average molecular weight (Mn) of not greater than 5000, and a viscosity modifier package to give the desired viscometrics comprising at least one multifunctional viscosity modifier. These oils meet stringent engine performance requirements and specifically give adequate varnish inhibition without very high treat levels of dispersants and/or use of specific detergent systems so avoiding problems of oxidation stability, compatibility and engine performance debits.

Abstract: The present invention is a high efficiency reformed methanol (syngas) gas turbine power plant. The invention utilizes a Back Pressure steam Turbine (BPT) to maximize the thermal efficiency and the power output of a reformed methanol gas turbine power generation system. Methanol feed is reformed to syngas (H.sub.2 and CO.sub.2) prior to combustion in the BPT turbine. The endothermic reforming reaction, and the generation of the significant amount of process steam essential for reforming, recovers most of the useful heat in the gas turbine exhaust gas. The process steam pressure is set by the gas turbine inlet requirements, and can be referred to as low pressure steam. Additional heat in the gas turbine exhaust gas is recovered by generating the system's process steam at an elevated pressure, rather than the required low pressure. This high pressure steam is used to drive a BPT, generating additional power and the discharged low pressure steam from the BPT is used as the process steam for the methanol reformer.

Abstract: A process for the modification of a small pore molecular sieve catalyst to increase its selectivity to ethylene in the production of light olefins from oxygenated compounds, particularly methanol. The catalyst is modified with phosphorus by incorporating a phosphonitrilic oligomer with the catalyst, and then calcining the catalyst at temperature sufficient to decompose the phosphonitrilic oligomer, and deposit from about 0.001 wt. % to about 50 wt. % phosphorus on the catalyst. This modification provides a novel composition in that it increases the ethylene selectivity of the catalyst in the production of light olefins from oxygenates as contrasted with a small pore molecular sieve catalyst otherwise similar except that it has not been so treated and modified with the phosphonitrilic oligomer.

Abstract: Processes for washing zeolites, preferably less than about 0.5 micron in size, with a microfiltration system employing a washing liquid, such as an aqueous solution or water (preferably deionized water), to produce zeolite crystals having a zeolite pH in the pH range of 9.4 to 10.0 are provided. The zeolite pH is determined by a special procedure.

A sample of the zeolite is dried and tested for its pH and if within the desired range, the batch of maximally concentrated slurry is dried.
