Abstract
Process for evaluating the coke and/or bitumen yield and quality of a plurality of refinery feedstocks, by (i) providing a plurality of refinery feedstocks, (ii) placing a sample of each of the plurality of refinery feedstocks on a heating device, (iii) heating each sample under vacuum to a temperature in the range 300° C. to 420° C. using the respective heating device while measuring the weight loss of the sample, and then (iv) (a) measuring the bitumen quality of the vacuum residues formed, and/or (b)(i) heating the vacuum residues to a temperature in the range 450° C. to 600° C. using the heating device, while measuring the weight loss of the sample, and then (ii) measuring the coke quality of the products formed.

A process for evaluating the coke and/or bitumen yield and quality of a plurality of refinery feedstocks, said process comprising:
- (i) providing a plurality of refinery feedstocks,
- (ii) placing a sample of each of said plurality of refinery feedstocks on a heating device,
- (iii) heating each sample under vacuum to a temperature in the range 300° C. to 420° C. using the respective heating device whilst measuring the weight loss of the sample, and then
- (iv)(a) measuring the bitumen quality of the vacuum residues formed, and/or
- (b)(i) heating the vacuum residues to a temperature in the range 450° C. to 600° C. using the heating device, whilst measuring the weight loss of the sample, and then
- (ii) measuring the coke quality of the products formed.
