Latest Patents

One of his latest patents is a method of making a shale oil modifier. This shale oil modifier is created from crude shale oil that has been dehydrogenated to achieve a viscosity between 1200-1800 poise at 60 degrees Celsius. The crude shale oil must contain sufficient basic nitrogen content, ideally around 2%-2.5% by weight, to ensure that the dehydrogenated product exhibits non-Newtonian properties when mixed with asphalt cements. The process involves a two-stage distillation followed by vacuum distillation to collect the residual fraction, which is then dehydrogenated with air to reach the desired viscosity.

Another significant patent is a method for recycling and rejuvenating asphalt pavement. This method includes milling and collecting a specific thickness of asphalt pavement from an existing roadbed. A shale oil modified asphalt is prepared, consisting of 5-25% shale oil modifier and 75-95% asphalt cement. The mixture also includes an aggregate made up of 60-70% virgin aggregate and 30-40% of the milled asphalt, which is then applied to the roadbed.
