Progress on the use of hydrogen donors for upgrading of heavy oil
摘要
Abstract
Due to high viscosity and high density of heavy oil, the viscosity reduction had firstly to be done to ensure heavy oil extraction, gathering, and processing. The hydrogen donated visbreaking process, which the hydrogen donor was added into the conventional visbreaking process to solve the problem of low processing depth,coking,and poor stability,was an efficient thermal viscosity reduction technology. This review first introduced the basic types of heavy oil pipeline transportations. Then the hydrogen donating mechanism,the effect of hydrogen donor,the species of hydrogen donor, determination of donatable hydrogen concentration and application of hydrogen donor were summarized. The selection of hydrogen donors should be determined according to process conditions and the properties of hydrogen donor. The key issue of affecting the coking and inhibiting coking is whether the active hydrogen can be timely closed the asphaltic free radicals.关键词
