Abstract

According to the present invention, organic material is converted to biogas through anaerobic digestion and the biogas is purified to yield a combustible fluid feedstock comprising methane. A fuel production facility utilizes or arranges to utilize combustible fluid feedstock to generate renewable hydrogen that is used to hydrogenate crude oil derived hydrocarbons in a process to make liquid transportation or heating fuel. The renewable hydrogen is added to a reactor operated so as to simultaneously desulfurize and hydrogenate crude oil derived hydrocarbons.

Abstract

According to the present invention, organic material is converted to biogas through anaerobic digestion and the biogas is purified to yield a combustible fluid feedstock comprising methane. A fuel production facility utilizes or arranges to utilize combustible fluid feedstock to generate renewable hydrogen that is used to hydrogenate crude oil derived hydrocarbons in a process to make transportation or heating fuel. The renewable hydrogen is combined with crude oil derived hydrocarbons that have been desulfurized under conditions to hydrogenate the liquid hydrocarbon with the renewable hydrogen or alternatively, the renewable hydrogen can be added to a reactor operated so as to simultaneously desulfurize and hydrogenate the hydrocarbons. The present invention enables a party to receive a renewable fuel credit for the transportation or heating fuel.

Abstract

The present invention relates to a modified Family 5 cellulase comprising a substitution of an amino acid at position 363 with a non-native alanine, serine or threonine, said position determined from alignment of the modified Family 5 cellulase with amino acids 71-397 of a Trichoderma reesei Cel5A amino acid sequence as set forth in SEQ ID NO:1 and enzyme mixtures comprising same. Additionally provided is a genetic construct comprising a nucleic acid sequence encoding the modified Family 5 cellulase and a genetically modified microbe comprising the genetic construct. The invention also provides a process for producing the modified Family 5 cellulase.
