A method for producing at least one fluorinated alkane comprising: a. providing a starting material stream comprising at least one alkene according to Formula (CX n Y 3-n)(CR 1 a R 2 b) z CX=CH m X 2-m and at least one alkane according to Formula (CX n Y 3-n)(CR 1 a R 2 b) z CHXCH m+1 X 2-m where: each X is independently Cl, F, I or Br, provided that at least two Xs are F; each Y is independently H, Cl, F, I or Br; each R 1 is independently H, Cl, F, I, Br or unsubstituted or halogen substituted methyl or ethyl radical; each R 2 is independently H, Cl, F, I, Br or unsubstituted or halogen substituted methyl or ethyl radical; n is 1, 2 or 3; a and b are each 0, 1 or 2, provided that a+b = 2; mis 0, 1 or 2; and z is 0, 1, 2 or 3, b. hydrogenating the starting material stream to produce an intermediate material stream by contacting said starting material stream with a reducing agent such that at least a portion of the alkene of Formula I is converted to the alkane of Formula II; c. separating a portion of the intermediate product stream into at least a first intermediate product stream comprising the alkene of formula I and the alkane of formula II and a second intermediate product stream comprising the alkene of formula I and the alkane of formula II; d. recycling the first intermediate product stream to step b; and e. hydrogenating the second intermediate product stream to produce a final product stream a. providing a starting material stream comprising at least one alkene according to Formula (CX n Y 3-n)(CR 1 a R 2 b) z CX=CH m X 2-m and at least one alkane according to Formula (CX n Y 3-n)(CR 1 a R 2 b) z CHXCH m+1 X 2-m where: each X is independently Cl, F, I or Br, provided that at least two Xs are F; each Y is independently H, Cl, F, I or Br; each R 1 is independently H, Cl, F, I, Br or unsubstituted or halogen substituted methyl or ethyl radical; each R 2 is independently H, Cl, F, I, Br or unsubstituted or halogen substituted methyl or ethyl radical; n is 1, 2 or 3; a and b are each 0, 1 or 2, provided that a+b = 2; mis 0, 1 or 2; and z is 0, 1, 2 or 3, each X is independently Cl, F, I or Br, provided that at least two Xs are F; each Y is independently H, Cl, F, I or Br; each R 1 is independently H, Cl, F, I, Br or unsubstituted or halogen substituted methyl or ethyl radical; each R 2 is independently H, Cl, F, I, Br or unsubstituted or halogen substituted methyl or ethyl radical; n is 1, 2 or 3; a and b are each 0, 1 or 2, provided that a+b = 2; mis 0, 1 or 2; and z is 0, 1, 2 or 3, b. hydrogenating the starting material stream to produce an intermediate material stream by contacting said starting material stream with a reducing agent such that at least a portion of the alkene of Formula I is converted to the alkane of Formula II; c. separating a portion of the intermediate product stream into at least a first intermediate product stream comprising the alkene of formula I and the alkane of formula II and a second intermediate product stream comprising the alkene of formula I and the alkane of formula II; d. recycling the first intermediate product stream to step b; and e. hydrogenating the second intermediate product stream to produce a final product stream
