Even if all of the HTF have tested the thermal stability and thermal oxidation stability and are qualified HTF, after extensive testing by think in actual use will still coking, but much between different brands of different amounts of coke it deteriorated state is different. This shows how much these two methods of testing and coke is not very strong correlation or not, the amount of coke is known for. All HTF scrap and coke are a relationship, if conducting oil and coke, carbon residue would not be a substantial increase in the total synthesis of conducting oil, oil will not be scrapped. HTF is a base oil and additives thereof. One view is that choosing the appropriate base oil, plus specialty additives HTF, quality generally not be a problem, but the company's point of view, I really do not exactly, or even very different. On the same kind of base oil, since different additive combinations, have a totally different quality performance. We were used to Class II base oil hydrogenation and seven major domestic production HTF complex compound additive products, respectively 7 HTF hydrogenation products. Quality is the final decision HTF HTF temperature formulation technology, which is not to explain the base oil is not important, choose highly refined base oils with completely by the above test method formulation technology to produce world-class thermal oil products.
