A stabilizing additive is prepared from a heavy distillate byproduct obtained from one or more waste plastic pyrolysis processes. The heavy distillate byproduct may include polynuclear aromatic hydrocarbons that each include between 2 and 4 condensed rings, heavy polynuclear aromatic hydrocarbons having between 5 and 10 condensed aromatic rings, and combinations of polynuclear aromatic hydrocarbons and heavy polynuclear aromatic hydrocarbons.

本发明涉及煤焦油回收技术领域，尤其涉及一种煤焦油预处理装置，包括静置箱，所述静置箱底部开口，静置箱内部滑动连接有呈对称分布的两个侧板，侧板连接有驱动机构，驱动机构用于带动侧板水平运动，静置箱底部转动连接有呈对称分布的两个翻板，翻板顶部均固定有密封垫片，所述翻板连接有转动机构，本装置在煤焦油静置分层完成并抽除上层液体后，驱动机构带动静置箱内两个侧板相互远离，这一动作不仅使底部堆积的粘稠下层物料变得松散、更易流动，同时配合翻板向下翻转打开排料通道，有效促使下层物料在重力作用下顺利、完整地排出，避免了因物料粘附在侧板及静置箱内壁而造成的残留和堵塞问题，显著提升了排渣效率和清洁度。

A substantially solid brick of non-volatile bituminous material has a shape that is defined by an irregular outer surface to minimize surface contact with nearby bricks when shipped in bulk. The overall shape is preferably that of a modified tetrahedron having three non-planar face surfaces, a top surface, and a surface or point. Both the top and bottom surfaces are preferably modified domed shapes comprised of several sections. The face sections are preferably modified concave surfaces comprised of several triangular sections that can be planar, concave, or convex. Curved edges connect the face sections to each other and can include several planar edge sections. The bituminous material can include additives, and the brick can further include a skeleton distributed throughout. The skeleton can be a customizable matrix, framework of fiber groups, or other structure and can include customizable buoyant features such as air pockets or capsules.
