Assignee:

Skyline Solar, Inc. - Mountain View CA

International Classification:

F24J 2/24

US Classification:

126658

Abstract:

In one embodiment, a solar receiver has a base plate having a first surface and a second surface, a plurality of solar cells positioned over and supported by the first surface of the base plate, and a multiplicity of fins extending outwardly from the second surface of the base plate. Each of the multiplicity of fins has a fin height axis extending generally perpendicular relative to the base plate, a fin length axis extending generally in parallel with the base plate, and a bottom end attached to the second surface of the base plate, wherein each of the multiplicity of fins are formed from a single, continuous sheet of metal arranged in a serpentine configuration, and wherein each of the multiplicity of fins have a plurality of undulations along the length axis of the fin.

Abstract:

Provided herein is a unique process that prepares a saturated hydrocarbon mixture with well-controlled structural characteristics that address the performance requirements driven by the stricter environmental and fuel economy regulations for automotive engine oils. The process allows for the branching characteristics of the hydrocarbon molecules to be controlled so as to consistently provide a composition that has a surprising CCS viscosity at −35 C. (ASTM D5329) and Noack volatility (ASTM D5800) relationship. The process comprises providing a specific olefinic feedstock, oligomerizing in the presence of a BFcatalyst, and hydroisomerizing in the presence of a noble-metal impregnated, 10-member ring zeolite catalyst.

International Classification:

C10M 105/00
C09K 5/10

Abstract:

Provided herein are hydrocarbon mixtures with controlled structure characteristics that address the performance requirements for finished lubricants driven by the stricter environmental and fuel economy regulations. The branching characteristics of the hydrocarbon molecules are controlled to provide a composition that has a unique and superior viscosity-temperature relationship and Noack volatility. An important aspect of the present invention relates to a saturated hydrocarbon mixture with at least 80% of the molecules having an even carbon number, with the branching characteristic of BP/BI in the range ≥−0.6037 (Internal alkyl branching)+2.0, where on average at least 0.3 to 1.5 of the internal methyl branches are located more than 4 carbons away from the terminal carbon when analyzed by carbon NMR. The saturated hydrocarbon mixture with such unique branching structure consistently exhibits a stand out performance in the cold crank simulated viscosity (CCS) vs Noack volatility relationship, which allows for the formulation of lower viscosity engine oils with improved fuel economies.

International Classification:

C10M 107/10
C10M 177/00

Abstract:

A polyalphaolefin composition is provided comprising trimers of C12 alpha-olefins and dimers of C14 alpha-olefins, where the ratio by weight of C12 trimer to C14 dimer is within a range of 4:1 by weight to 1:4 by weight, where the C12 trimer enriched polyalphaolefin has an average branching ratio 0.20, and where the average branching ratio for all C12 trimers and C14 dimers is between 0.19 and 0.26. The composition has a boiling point distribution where less than 30% by weight of the composition has a boiling point between 420 C. and 455 C., and the resulting base oil has a kinematic viscosity of about 3.3 to 4.7 cSt at 100 C.
