摘要： The present invention relates to a process for co-gasification of two or more carbonaceous feedstock, said process comprising combusting a first carbonaceous feedstock having high calorific value with low ash and high hydrogen content, to produce a heated effluent; carrying the heated effluent to second reactor where the heated effluent reacts with a second carbonaceous feedstock, having low calorific value with high ash and low hydrogen content, to produce synthesis gas. The present invention also relates to an apparatus for co-gasification of two or more carbonaceous feedstock, comprising a first reactor (3), having a first feedstock inlet port (1), a oxygen or air inlet port (2), a steam inlet port (9), a ash removal port (7), and a solid recycle port (6); a first cyclone separator (5) connected to the first reactor (3) through a first cyclone separator inlet port (4); a second reactor (16), having a second feedstock inlet port (10), and a ash removal port (15), the second reactor is connected to the first cyclone separator (5) through a gaseous inlet port (8); and a second cyclone separator (12), having a fine particles removal port (13), and an effluent port (14), wherein the second cyclone separator is connected to the second reactor through a second cyclone separator inlet port (11).

摘要： Provided is a method for predicting kinematic viscosity of a fraction of a crude oil to optimize selection of crude oils. The method includes receiving parameters of the crude oil, such as Vacuum Residue yield and Conradson Carbon Residue (CCR), content as an input. The method also includes determining kinematic viscosity of the fraction of the crude oil at a first predetermined temperature based on a first correlation model between the physical parameters of the crude oil and the kinematic viscosity at the first predetermined temperature. The method further includes generating the kinematic viscosity of the fraction of the crude oil at the predetermined temperature based on the first correlation model corresponding to the input. Also provided is a system for predicting kinematic viscosity at a predetermined temperature to optimize crude oil selection. Further provided is a method for estimating an amount of cutter stock for crude oil processing.
