## Abstract

A process is provided for the catalytic cracking of a glyceride oil feedstock with a catalyst composition containing a phosphorus-containing ZSM-5 light olefins additive.

## Claims

### Claim 1

A process for catalytic cracking of a feedstock consisting of glyceride oils, the process comprising:
(a) catalytically cracking the feedstock consisting of glyceride oils in the presence of a single catalyst at catalytic cracking conditions to obtain a product stream comprising hydrocarbons; and
(b) separating one hydrocarbon fraction from the product stream: wherein the single catalyst consists of:
(i) 25 to 50 wt. % of ZSM-5;
(ii) 3 to 15 wt. % of phosphorus, measured as P2O5;
(iii) 5 to 45 wt. % of a clay;
(iv) 5 to 20 wt. % of a binder; and
wherein the process is a fluid catalytic cracking process.

### Claim 2 (depends on 1)

The process of claim 1, wherein at least 80 wt. % of glyceride oils are triglycerides.

### Claim 3 (depends on 1)

The process of claim 1, wherein the glyceride oil is selected from rapeseed oil, colza oil canola oil, tall oil, sunflower oil, soybean oil, hempseed oil, cottonseed oil, corn oil, olive oil, linseed oil, mustard oil, palm oil, peanut oil, castor oil, coconut oil, camellia oil, jatropha oil, a microbial oil, animal fats, fish oil, lard, tallow, train oil, recycled fats from the food industry, and any combination thereof.

### Claim 4 (depends on 1)

The process of claim 1, wherein the catalytic cracking conditions include a temperature of from 450° C. to 650° C.; a pressure of from 100 kPa to 1100 kPa; and a catalyst-to-oil mass ratio of from 3 to 12.

### Claim 5 (depends on 1)

The process of claim 1, further comprising fractionating the product stream into one or more hydrocarbon fractions.

### Claim 6 (depends on 5)

The process of claim 5, the one or more hydrocarbon fractions is selected from light olefins and gasoline.
